⏱️ 5-minute start

The shortest path to a memory your AI reads cheaply (memglow 0.6.3).

1. Install and run the memory server (Node 18+, no build, zero dependencies) on your notes folder:

   npx memglow memory-server --root ~/knowledge --listen 127.0.0.1:8000 --read-write --levers

   (--root is your Markdown folder; drop --read-write to try it read-only first. --levers is the all-in-one mode that applies the token levers below — see All-in-one. A Docker image of the viewer is described under Docker.)

2. Connect Claude Code, with the headersHelper so every call of a conversation shares one session (the per-session savings need it, see Session identity with Claude Code):

   {
     "mcpServers": {
       "memglow": {
         "type": "http",
         "url": "http://127.0.0.1:8000/mcp",
         "headersHelper": "node /path/to/memglow/hooks/memglow-headers.js"
       }
     }
   }

3. Open the viewer (npx memglow, then http://127.0.0.1:4747) to watch the memory light up.

Recommended profile — it is already the default, there is nothing to configure:

| Setting | Default since 0.6.0 | Why | |---|---|---| | tools.profile | minimal | 11 tools listed instead of 23: the compat tools (schema_*, view_note, read_content, list_workspaces, list_memory_projects, create_memory_project, delete_project, basic_memory_diagnostics, ChatGPT's search/fetch) are not listed (≈ -2,500 tokens at every session start) but stay callable by name. MEMGLOW_TOOLS_PROFILE=full lists everything. | | stateView | on | A journal-style note (appended dated sections) is read as its current state plus the 2 latest entries; the older ones are named, one call away. The only token lever with a measured gain in production. MEMGLOW_PROXY_STATE_VIEW=0 turns it off. | | multiQuery, aliases, sizeWarning | on | Fewer search round trips, learned synonyms, one-line "this note is large" hint. | | Everything else | off | Opt-in, see Advanced. |

These defaults apply wherever the levers run (the all-in-one server with --levers, or the MCP proxy). The memory server also tells you what it costs: the memory_core accounting line ends with "Session start ≈ N tokens" (average memory_core + tools/list answer served), and so does the control panel.

Removed in 0.6.0

Dead weight, measured and removed: deltaRead (13), alreadyLoaded (8, with its exempt-clients and require-activity rules), indexHint (12), searchDetails (2), suggestions (3) and sessionBudget (18). Their environment variables and proxy keys are still accepted and ignored — one start-up log line each (memglow: ignored: lever X removed in 0.6.0) — so an existing deployment keeps starting. The AI duplicates worker is gone too: possible duplicates are listed by the structure audit as rule D1 (report-only, no AI, no merge). See the CHANGELOG.

✨ Features

| Feature | What it does | |---|---| | 🧠 Live 3D brain | Every note is a glowing neuron, every [[wikilink]] a connection. Recent notes shine brighter. | | ⚡ Assistant activity, live | Hooks for Claude Code, Codex, Gemini CLI, Cursor, Windsurf, Copilot and Cline — or an MCP proxy for any other client — report each read, search and write. The note flashes — 🔵 cyan for a read, 🔴 red-orange for a write, 🟣 violet for a search — and comets run along its links. | | 🎥 Camera that follows | Glides to what the assistant touches, frames a search's results, drifts back to the overview after a few calm seconds. | | 🪙 Memory cost | See roughly how many tokens your assistant spends reading its memory (≈ bytes ÷ 4): tokens read today and over 7 days, the notes that cost the most, notes too large to read comfortably, notes never read in 30 days. For each large note, a split along its ## sections and a Copy prompt for your AI button. More | | 🗂️ Themes & sub-themes | Notes cluster by theme with relay bubbles for sub-themes — from frontmatter or folder names. Organisation spots notes about one subject scattered across sub-themes; Always loaded shows what the index and your CLAUDE.md / AGENTS.md cost at every session. | | 🧩 Memory rules (built in) | memglow ships with memory-hygiene rules calibrated on real use, delivered automatically to your assistant through the MCP proxy — on by default, no setup needed. More | | 🛡️ Protected groups | At first run, pick the big groups no assistant may ever move notes across (rename how they are shown if you like). More | | 🗄️ Archive tier | Sections unused for months (≈ 3.5 by default) move, word for word, to an archive note of the same theme, with a one-line summary each; the live memory stays small, nothing is lost. More | | 🎛️ Tune it live | Background, glow, bubble size, size by links or token cost, names and name distance, spread, gravity, spacing, signal speed, links at rest, auto-rotate, find-a-note. Saved in your browser. Settings | | 🎚️ Control panel | Settings → Control: every MCP proxy lever in one place — current value, where it comes from (env / page / file / default), locked by an environment variable or not — switch the day-one ones from the page itself. More | | 🌐 8 languages | English, French, German, Spanish, Brazilian Portuguese, Japanese, Korean, Simplified Chinese — picks your browser's language, switch it any time. Languages | | 🔒 Private by design | Localhost by default, read-only access to your notes (the optional assistant writes only what you approve), secret-looking lines masked. Hooks send note names only, never content. No CDN, no analytics. | | 📦 Zero dependencies | One command, Node 18+. No build step, no database. Or one Docker container. |

🪙 Memory cost

Below the graph, the Memory cost panel shows where your assistant's reading goes — on your own memory, from the activity your hooks report:

• Tokens read today and over 7 days, tokens written over 7 days, the size of the whole memory and of the index note.
• "N notes = X % of tokens read" — reading is often concentrated on a few notes.
• Most expensive to read (7 days): the top 10 by tokens read (reads × size). Click a note to open it in the graph.
• Too large: notes above 5,000 tokens (largeNoteTokens), with their ## sections and a deterministic split suggestion (consecutive sections grouped into parts of about 2,000 tokens, splitChunkTokens).
• Never read in 30 days — once 30 days of counts exist (before that: "Data since …").
• Copy prompt for your AI on each large or costly note: a ready-to-paste prompt with the note, its size, its reads, the threshold and the suggested parts, plus rules that keep the memory consistent (same group and folder, top-level groups unchanged, theme/subtheme frontmatter kept, [[links]] kept valid, hub and spoke — the original becomes a short summary that lists the new notes, each new note links back to it only, and the new notes stay out of the index — only the agent's memory tool is used, and the plan is shown before anything is written).
• Structure — how far the memory is from hub and spoke: sub-notes listed in the index, "Siblings:" lines, missing links back to a summary. Tidy fixes the mechanical ones itself (no AI, no tokens); with the assistant, ambiguous cross-links in running text go to your AI, which may only keep or remove each one.
• Organisation — notes about one subject scattered across several sub-themes of the same group: "5 notes about “docker” are spread across 4 sub-themes of Knowledge — group them under “ops”?", with the notes, the reasons, Copy prompt for your AI and (with the assistant) Do it with …. Read-only detection, never across big groups; the rules are below.
• Always loaded · every session — what your assistant receives before doing anything: the index note plus the instruction files you list in alwaysLoaded (~/.claude/CLAUDE.md, ./CLAUDE.md, AGENTS.md…). memglow only reads their size, never their content; the page shows the path you wrote and ≈ tokens. ≈ X tokens per session × N sessions per day ≈ Y tokens per day — sessions per day are estimated from the reads of the index note over the last 7 days (an assistant reads it once per session), otherwise sessionsPerDay (default 5). Above indexWarningTokens (default 2,000) you get a tip: trim the index / CLAUDE.md. When an index line's hook is longer than indexTrimMaxChars (default 90 characters), a Trim the index (N lines, ≈X tokens/session) button appears (with the assistant): fully deterministic, no AI — each hook is cut at its last clause or word boundary, and nothing is ever lost: the dropped words must already be in the linked note's description or body, or the plan also writes them there as a new description: line; a line whose note is missing or whose existing description does not cover it is left exactly as it is. The index text plus the rendered memory-hygiene rules form a cache-stable prefix: identical bytes every session unless one of them actually changes, which is what lets an LLM provider's prompt cache hit. When it changes often (3+ times in a week) you get a tip that batching index edits keeps that cache warm (cached input tokens cost ≈0.1× — the figures are also in the memory_health MCP tool).
• Maintenance (N) — the same three deterministic tiers above (archive, split, index trim), run on a schedule (once at start, then every maintenanceEveryHours, default 24 — see Configuration) and ranked by estimated token gain, so you do not have to open three different blocks to find out there is something to do. Each item has a Do it button that starts the matching proposal through the normal pipeline above (nothing is ever applied from this list itself) and a Dismiss button; a dismissed item stays dismissed. Also exposed read-only as the maintenance_proposals MCP tool.
• Time to find a note · 7 days — from the activity memglow already receives: for each search, the first read by the same assistant (same source, machine and channel) within 2 minutes. Median time to the note, median steps (each extra search before the read is one more step), the share of searches with no read after, and the 5 slowest or missed searches — note titles only. A search answered from its results alone also counts as "no read after": memglow cannot tell it from a search that gave up. Searches that found nothing are counted only through the MCP proxy (a hook reports nothing then).
• Memory engine speed · 7 days — how long the memory server takes to answer, per tool type (search / read / write): calls, median (p50) and 95th percentile (p95). Measured by the MCP proxy for every tool call (request forwarded → response back) and sent with the activity as durationMs (memglow keeps it only if it is a number between 0 and 600,000 ms). Hooks have no timing, so without the proxy this block stays empty. Slow-search alert: shown when, with at least 10 searches in each window, the median of the last 24 hours is at least 2× the median of the 6 days before and at least 250 ms slower (the floor keeps a 20 → 45 ms wobble on a fast local server from alerting).

How Organisation decides (deterministic, explainable, capped at 5 suggestions of 12 notes): keywords of a note = words of 4+ letters of its title, id and description (minus common words and id prefixes such as reference-). Two notes of the same group are strongly tied when they score 3 or more: +2 for a [[link]] between them, +1 per shared keyword (at most +3). (1) Scattered: notes joined by strong ties that span 2+ sub-themes and number 3+ → regroup them under the sub-theme that already holds most of them; the topic is the keyword they share most; the score is the sum of their ties. (2) Alone: the only note of a sub-theme, strongly tied (total ≥ 3) to one other sub-theme of its group → move it there. Note bodies are never read for this.

Numbers are estimates (≈ bytes ÷ 4, not a tokenizer), meant to compare notes with each other — memglow promises no saving. Memory cost never touches your notes: the counts (note ids, days and numbers only; per-day counts kept 90 days, plus the last day each note was read, found or written; for Time to find a note and Memory engine speed, 8 days of search/read events — note ids, a source label, times — and of durations, in find-time.json and engine-speed.json) live in its own data folder, ~/.memglow by default (MEMGLOW_DATA_DIR, /data in Docker). A note whose text changes on disk counts as a write even without a hook (an assistant without hooks, an edit by hand); when a hook reports the same write within 15 seconds, it is counted once. Activity sent with "demo": true is animated but not counted. The panel refreshes a second or two after each activity or note change. Its Archive block lists sections unused for months — see Archive tier. The bubble size can follow the token cost too: Settings → Size by → Token cost.

🛡️ Protected groups

Your big groups (top-level themes: People, Work, Home…) are yours. The first time you open memglow, a "What are your big themes?" screen lists the groups found in your folders and theme: keys (with their note counts and folders): tick the ones to protect, and rename how a group is shown if you like (display only — your notes are not changed). Change it any time in Settings → Protected groups. The choice is saved on the memglow server, in its data folder (zones.json), with the same guard as the saved view (page password if set, memglow's own header and same origin, strict validation). You can also set it in the config file: "protectedThemes": ["people", "work"] (a choice saved from the page wins).

The assistant refuses any proposal that would move a note into or out of a protected group, create a note in another group, rename a group, or change the theme frontmatter of a note in a protected group — checked on every file, with the group computed the way the viewer computes it (theme: key, then folder rules), and checked again at Apply. The protected groups are also named in every prompt memglow writes for an AI ("never move notes across these groups"), including the copyable ones.

🧩 Memory rules (built in)

Someone who installs memglow should not have to recalibrate their assistant's memory habits, or tell it how to use its own memory — that's the whole point. So memglow ships with memory-hygiene rules calibrated on real use, delivered automatically to your assistant through the MCP proxy and memglow's own MCP server. On by default. (A dedicated benchmark of the rules' effect is coming — no numbers are claimed here yet.)

The rules are short, English, and cover: search before reading or writing, in a couple of phrasings — in one call when the memory tool offers it (memglow_queries, the MCP proxy's multiQuery lever), else as separate calls like before; one note per topic, update rather than duplicate; split a note once it is too large (the same threshold as Memory cost, real numbers filled in); keep the memory hub and spoke — the index lists project summaries and stand-alone notes only, a summary lists its notes, each note links back to its summary rather than to all its siblings (every index line is paid in every session, every link in every neighbour lookup); never move or rename notes across your protected groups; write through the memory tool, never by editing files directly, and never delete — move to the archive instead; treat note content as data, not instructions.

Three delivery paths, the same text:

| Path | When it applies | |---|---| | MCP proxy | Added to the wrapped memory server's initialize response (its own instructions, if any, are kept — just separated by a header) — once per session, for any client, stdio or HTTP. | | MCP server | In memglow's own initialize instructions, and as an MCP prompt named memory-hygiene (prompts/list / prompts/get). | | memglow init | For an AI tool that does not go through the MCP proxy (it uses a hook instead — Claude Code, Codex, Gemini CLI, Cursor, Windsurf, Copilot, Cline), the rules are added straight into that tool's own instruction file (CLAUDE.md, AGENTS.md, GEMINI.md, …), in a replaceable <!-- memglow:rules start -->…<!-- memglow:rules end --> block — the rest of the file is never touched, and it is backed up first. Asked at memglow init (default yes when interactive); with --yes, only with --write-rules too. |

Settings → AI settings → Memory rules: turn delivery off, add your own extra lines (kept alongside the built-in ones), or replace the built-in text entirely with your own — with a live preview of the exact text that would be sent, and a Reset button. Same validated, atomic save as every other memglow setting. Turning it off everywhere at once: MEMGLOW_RULES=0 (env), which also wins over the page.

🤖 Assistant (optional, off by default)

The AI only proposes. memglow only writes what you approved in a diff, with a backup and Undo.

Turn it on and every large or costly note in Memory cost gets a Do it with Claude button next to Copy prompt for your AI, and an Assistant panel appears below Memory cost:

1. Ask — memglow sends the note (and its context: title, group, folder, sections, suggested split, the lines of other notes that link to it) to the AI you chose. The AI gets no tool at all: it cannot read, write, run or fetch anything. It answers with one JSON proposal: a short summary for the original note, the new notes (title, file name, content), and optional link updates in the notes that point to it.
2. Check — memglow validates the proposal and refuses it, with the reasons, if anything is off: a file name with a path or .., a new note that would replace an existing one, content missing from the original note (every non-empty line must be found in a part or in the summary), a part that brings its own frontmatter, a summary that does not link every part, a link update outside the notes that link to the original. New notes get the original note's theme / subtheme lines, so the group never changes; the original note keeps its frontmatter byte for byte. Nothing is ever deleted, moved or renamed.
3. Review — the panel shows the exact changes, file by file (added lines in green, removed in red), the AI's short note, and the gain: tokens to read the note today vs the new summary.
4. Apply — the Apply this plan button asks the server for a one-time confirmation token (random, 2 minutes, single use, bound to this proposal; typing "yes" anywhere does nothing). memglow then checks that no file changed since the proposal, backs up the notes it will modify — a snapshot commit if your notes are a git repository (only those files, author memglow, your hooks not run), otherwise a copy in <dataDir>/backups/<time>-<job>/ — and if the backup fails, nothing is written. Files are written atomically; a new note never overwrites a file.
5. Undo — restores the backup and removes the new notes, except files you changed since (those are listed and left alone). The last 5 applied changes keep their Undo button; every backup folder also has a job.json for a manual restore.

Lines that look like secrets (API keys, tokens, password: …) never leave your machine: memglow replaces them with placeholders before sending the note, checks they all come back once, and puts the real lines back when writing. Everything else in the note is sent to the AI you chose.

Turn it on — in memglow.config.json:

{ "assistant": { "enabled": true, "provider": "claude-code" } }

or MEMGLOW_ASSISTANT=1. It needs MEMGLOW_SHOW_BODIES on (you must see what will be written) and a data folder outside your notes (for backups). Off, its routes answer 404 like any unknown route, and no button or panel is shown.

Providers (assistant.provider sets the default; every ready provider can be picked in the panel when you ask):

| Provider | Runs | Where your note goes | Status | |---|---|---|---| | claude-code (default) | your own Claude Code CLI (claude), your subscription or key | wherever your CLI sends it (Anthropic by default) | ✅ supported | | anthropic | Anthropic Messages API, your API key | api.anthropic.com | ✅ supported | | openai-compatible + preset: "openai" | OpenAI Chat Completions, your key | api.openai.com | ✅ supported | | openai-compatible + preset: "mistral" | Mistral, your key | api.mistral.ai | ✅ supported | | openai-compatible + preset: "openrouter" | OpenRouter, your key | openrouter.ai (then the model's vendor) | ✅ supported | | openai-compatible + preset: "ollama" | Ollama on this machine, http://127.0.0.1:11434/v1, no key | nowhere: it stays on your machine | ✅ supported | | openai-compatible + preset: "lmstudio" | LM Studio on this machine, http://127.0.0.1:1234/v1, no key | nowhere: it stays on your machine | ✅ supported | | codex, gemini, cursor | their CLIs | — | not yet: memglow has not verified a way to run them with no tool at all |

Any other OpenAI-compatible server works with baseUrl instead of preset (memglow calls <baseUrl>/chat/completions).

claude-code is run as claude -p --tools "" --strict-mcp-config --restricted --permission-mode dontAsk with a deny-all permission rule, no session saved, the prompt on stdin (never on the command line, never through a shell), in an empty folder of memglow's data folder. Options: command (path to claude), model, maxBudgetUsd, timeoutMinutes (default 10). Claude Code must be installed and signed in (run claude once in a terminal), and recent enough to have --restricted: memglow checks claude --help and refuses an older one ("This Claude Code is too old… Update it with claude update."). The panel lists the providers it detects and says clearly when one is missing.

HTTP providers (anthropic, openai-compatible) — examples:

{ "assistant": { "enabled": true, "provider": "anthropic", "model": "claude-sonnet-5-5" } }

{ "assistant": { "enabled": true, "provider": "openai-compatible", "preset": "ollama", "model": "llama3.1" } }

The top-level model, baseUrl, preset, maxTokens, apiKeyEnv, apiKeyFile apply to the default provider. To have several ready at once, give the others their own section, e.g. "anthropic": { "model": "…" } or "openai-compatible": { "preset": "lmstudio", "model": "…" } inside assistant. anthropic defaults to claude-sonnet-5-5 and maxTokens 32000; openai-compatible needs a model (the name your server knows) and sends max_tokens only if you set maxTokens.

• The API key is never in memglow.config.json — memglow refuses to start the assistant if it finds apiKey (or key, token, secret…) there. Put it in the environment variable MEMGLOW_ASSISTANT_API_KEY (or the variable named by apiKeyEnv, e.g. "apiKeyEnv": "ANTHROPIC_API_KEY"), or alone in the file assistant-api-key of memglow's data folder (apiKeyFile to rename it) with mode 600 — a file other users can read is refused, with the chmod to run. The key is sent only to the provider's address (x-api-key for Anthropic, Authorization: Bearer otherwise), never to the browser (the panel only says key: set / not set), never logged, never in an error message. Ollama and LM Studio need no key.
• HTTPS is required for any address that is not this machine (127.0.0.1, ::1, localhost): http:// to anything else is refused, and so is a URL with a user name or password in it. Redirects are not followed. In Docker, a model on the host is not loopback from inside the container: run memglow with host networking, or put the model behind HTTPS.
• Before you click Propose, the panel says where the note goes: Local model — nothing leaves your machine, or Your note will be sent to api.example.com.
• What is sent is exactly the prompt built for every provider, nothing else from your memory: the note you picked (secret-looking lines replaced by placeholders), its title, group, size and sections, the lines of other notes that link to it, the names of your existing notes (so new files never reuse one), and your optional extra instructions. No tool is declared in the request (no tools / functions); an answer that tries to call one is rejected, as is an answer that is not valid JSON, cut off, or larger than 4 MB. Each request is time-limited (timeoutMinutes). HTTP errors are reported plainly (401 key refused, 429 rate limit with its delay, 5xx).

AI settings (Settings → AI settings) — the same choices as the first run, kept there for good: the default provider and the configured ones (add, remove, several at once), each with key: set / not set / not needed, Test connection, and its settings — model (known names offered, any valid name accepted), address or preset, max output tokens, temperature (only for providers and models that accept it), time limit, cost cap per request (--max-budget-usd for Claude Code; for the APIs, max output tokens × the price, shown as an estimate), and Always ask before sending a note to this provider (on by default for every provider that is not on this machine: a box to tick before Propose). Below: the assistant's own settings (a note is too large above, size of the parts, lines allowed to go missing — 0 by default, with a warning above —, backup auto / git / copy) and a usage box: requests per provider over 7 and 30 days, tokens (≈ characters ÷ 4) and an estimated cost from the price you set (list prices of Anthropic's models are pre-filled), from memglow's own counts (assistant-usage.json, numbers only) — no external call.

Order of priority: environment variable > the page > memglow.config.json. Every value is checked on the server against a closed list of fields with bounds; anything else is refused.

Claude Code subscription (no API key) — the claude-code provider uses your Claude Code sign-in. Model: an alias claude --model accepts (opus, sonnet, haiku, fable, best, default, sonnet[1m], opus[1m]) or a full id (claude-…); empty = your Claude Code default. Where claude is not signed in (Docker, a server), use a token from claude setup-token as CLAUDE_CODE_OAUTH_TOKEN (see Docker); typed in the page it is saved in claude-code-oauth-token (mode 600) and passed only in the environment of the claude process memglow starts (an ANTHROPIC_API_KEY there is then left out, as it would win over the subscription).

Keys typed in the page — saved by their own route (POST /api/setup/secret), one file per provider in the data folder (assistant-api-key-<provider>, mode 600, written atomically), never sent back (only set / not set and where it comes from), never logged, removable with Remove key. A key sent anywhere else (a settings body, a model field) is refused. Order: apiKeyEnv or MEMGLOW_ASSISTANT_API_KEY_<PROVIDER> > MEMGLOW_ASSISTANT_API_KEY > the page's file > assistant-api-key. Changing the address of a provider that has a key needs the same conditions as typing one (this computer, or password + HTTPS).

Regroup (Organisation suggestions). Do it with … on an Organisation suggestion asks the AI which notes of that suggestion should share one sub-theme. The AI receives only metadata — ids, titles, descriptions (secret-looking lines masked), current sub-themes and the folders of the group, never a note's text — and answers {"subtheme", "moves": [{"note", "folder"?}], "notes"}. memglow then changes only the subtheme line (or an existing sous_theme line; one is added if missing) of the notes moved, and moves a file only to a folder of the same group when the AI names one. Refused, with the reasons: a key that would change or rename a group (theme, group, rename…), a note memglow did not list, an unknown folder, a file that would replace another, a note that would leave its group (or a protected group), any change of a note's text or theme line. Links by name stay valid (names never change); links written as a path ([[folder/note]]) to a moved file are updated. Same diff, one-time token, backup and Undo as a split (Undo puts a moved note back in its old place).

Tidy (hub and spoke). Detection is pure and conservative: a note counts as part of a summary only when it says so (part_of: in its frontmatter — memglow's own splits write it — or a header line such as Split on … from [[summary]], Part of … [[summary]], Up: [[summary]]), or when the structure leaves no doubt (same folder, linked both ways, cited by nobody else). Notes that merely link to each other are never treated as parts. Index lines that point to a part, pure "Siblings:" lines and missing links back are fixed without the AI; only ambiguous links inside a sentence are sent to it, and it may only answer keep or remove for each — memglow then removes just that [[link]], nothing else. Never deletes a note. Same diff, backup and Undo as a split.

With basic-memory, memglow writes the Markdown files directly; basic-memory re-indexes changed files on its own (its sync watches the folder). New notes have no permalink until basic-memory adds one.

🗄️ Archive tier

Parts of notes nobody has used for months still cost tokens every time their note is read. The archive tier moves those sections (not only whole notes) out of the live memory, into an archive note of the same theme, and keeps a compact archive summary — one line per archived section. Retrieval order for the assistant: the live memory first; the archive summary only when nothing was found there; then the archived section itself. Nothing is ever lost: each section is moved word for word, and its note keeps a one-line link to it.

Which sections are "dormant" (Memory cost → Archive block, read only). A section S of note N is listed when all of this holds:

1. Enough history: activity counting started at least archiveAfterDays days ago (default 105, about 3.5 months). Before that, the block says Not enough data yet since and when it will start.
2. N was not read during those days, and did not appear in search results (activity counters, per note).
3. S was not edited during those days: checked per section once memglow's section log (section-ages.json in its data folder: a hash and a first-seen day per section, never text) covers the whole window; until then, per note (no write counted, and the note's body unchanged on disk since the cutoff).
4. S is a heading section (the note's top heading level, sub-sections included) of at least archive.minSectionTokens (100) tokens — never the text before the first heading, an index note, a note without a theme, or a note already in the archive folder. At most archive.maxSuggestions (20) are listed, biggest first.

Honest limits. The counters only see whole-note reads and searches: a hook or the MCP proxy reports "note X was read", never which part. So reads and searches are judged per note — a note read once in the window keeps all its sections live — and only edits can be judged per section. A read nobody reported (an assistant without hooks, you in an editor) is invisible to memglow. After an archive, the note counts as written, so with the per-note check its other sections wait another full window. The figures are estimates (≈ bytes ÷ 4).

The move — for each chosen section:

• the section goes, verbatim, to archive/<theme>-archive.md (created with theme: <theme>, subtheme: archive, memglow_archive: true), right after a marker line <!-- memglow:archived from="<note>" date="YYYY-MM-DD" -->; an existing archive note is only appended to;
• the original note keeps one line in its place, e.g. Archived: Old plan → [[projects-archive#Old plan]] (2026-10-01); nothing else in it changes, frontmatter included;
• archive/archive-summary.md (memglow_archive_summary: true) is rebuilt from every archive note, one line each, newest first: - 2026-10-01 · Old plan · from [[old-project]] → [[projects-archive#Old plan]] · ≈ 420 tokens. About 25-30 tokens per line: small by construction (the panel shows its size).

Three ways to do it, from the Archive block (tick the sections you want):

• Copy prompt for your AI — always there: a ready-to-paste prompt asking your assistant to do the move with its own memory tool, in exactly this format, showing you the plan first.
• Prepare without AI (assistant on) — memglow builds the move itself. A verbatim move needs no judgement, so this is the safest path.
• Do it with (assistant on) — the AI only reviews the list (titles, sizes, last read day, a few lines of each section, secret-looking lines masked) and answers which sections to archive and which to keep live, with a reason. memglow then builds the move itself: the AI never writes any file content.

Either way it goes through the assistant's safeguards: memglow checks the plan — nothing lost (each original note rebuilds exactly from the note and its archived sections; each section is in its archive note once, word for word), same theme (every archive note has the theme of the notes it receives; no theme/subtheme of an existing note changes), no overwrite (a file memglow did not make is never touched; a new file never replaces one), valid links (every [[…#…]] names an existing note and heading) — shows the exact diff, and writes only after Apply this plan (one-time server token), after a backup, with Undo. The check runs again right before writing.

For the assistant: memglow-mcp has a read-only archive_lookup tool, and the MCP proxy an optional archive hint (lever 6, off by default). Search engines that index your notes folder (basic-memory…) still index the archive notes: archived text stays findable, it just stops costing tokens when its original note is read.

🎛️ Settings

The Settings panel on the graph. Your view — these settings, the layout of the bubbles (where they are, which ones you pinned by dragging) and the camera — is saved on the memglow instance, in its data folder (view.json in ~/.memglow, MEMGLOW_DATA_DIR, or the /data volume in Docker). memglow has one user per instance, so every browser and device that opens it gets the same view: set it up on your laptop, open it on your phone, same picture. The page also keeps a copy in the browser (localStorage, keys memglow.*) and uses it if the server does not answer within a few seconds.

| Section | Setting | What it does | |---|---|---| | Display | Glow | strength of the glow | | | Names | none, active notes only, or all | | | Name distance | names fade out beyond this distance (20 = always shown) | | | Background | Deep (gradient and faint stars, default), Plain, Night blue, Light | | | Bubble size | 0.5× to 3× | | | Size by | number of links, or token cost | | | Group by theme / Sub-themes | clusters and sub-theme bubbles | | | Language | interface language — see Languages below | | Motion | Spread, Gravity | size of the graph, pull towards each theme | | | Minimum spacing | gap kept between bubbles; wins over gravity | | | Signal speed | how fast comets run along the links (default 1.8 s per link) | | | Auto-rotate, Follow activity, Dragged bubbles stay put | camera and dragging | | Forces | Repulsion | 0.3× to 3×; multiplies how strongly every bubble pushes every other one away | | | Link force | 0.2× to 3×; multiplies the tension of every link, on top of Gravity (which only tunes the sub-theme threads) | | | Link distance | 0.3× to 3×; multiplies the resting length of links alone, independently of Spread (which changes repulsion and distance together) | | | Reset forces | puts Repulsion, Link force and Link distance back to 1× (today's look); Spread/Gravity/Minimum spacing and the current layout are untouched | | Links | Links at rest | hidden, subtle or visible; comets light the way anyway | | | Link opacity | 0× to 3×; intensifies whichever "Links at rest" level is chosen, it is not a fourth level | | | Ambient flow | slow comets at rest |

Drag a bubble to move it, double-click it to release it; double-click the background to go back to the overview. Rearrange starts again from a fresh layout (your settings stay). A note added later appears next to its sub-theme bubble, without shaking the saved layout. With reduced motion on, a saved layout is restored without animation.

On a phone (under 640 px wide, or a phone held sideways), the controls stop covering the graph: the legend folds behind a Themes chip (folded the first time; your choice is then remembered in this browser), Find a note behind a magnifier, and Settings behind a gear that opens a bottom sheet — close it with Close settings, a tap on the dimmed background, a swipe down on its handle, or Escape; the focus goes back to the gear. The activity journal shows each entry on two lines (action · group, then note · source), Memory cost names wrap instead of being cut, and the Assistant, Protected groups and Archive blocks get full-width rows and larger buttons. Nothing changes on a larger screen.

🌐 Languages

The interface ships in English (reference), French, German, Spanish, Brazilian Portuguese, Japanese, Korean and Simplified Chinese. It picks your browser's language on first visit (navigator.languages, falling back to English for anything else), and you can override it any time with Settings → Language — the choice is saved with the rest of your view, like every other setting, so it follows you to any browser or device that opens the same memglow instance. Product names (Claude Code, Codex, Cursor, Ollama…) and the word "token" are never translated, by design. Prompts memglow builds for your AI (the Copy prompt for your AI text, and what the optional assistant sends) always stay in English, whatever the interface language — the AI reads them, not you.

Numbers and dates follow the interface language too (Intl, with the language you chose, not the browser's locale): "≈ 1 234 tokens" and "30 sept." in French, "1.234" and "30. Sept." in German, "9月30日" in Japanese. The two exceptions keep fixed English formats on purpose: the prompts for your AI, and the lines memglow writes into the archive summary (an ISO day and "≈ 1,234 tokens", read back by memglow itself).

Zero runtime dependency, no build step: each language is one JSON file in public/i18n/, loaded by the small public/i18n.js on demand. To add a language:

1. Copy public/i18n/en.json to public/i18n/<code>.json (a code like it, or pt-PT) and translate every value — technical, sober tone; keep every {placeholder} exactly as in the English file; a key that needs a plural keeps the { "one": "…", "other": "…" } shape (a language without grammatical plural, like Japanese here, may give one plain string instead). Set _meta.name (English name) and _meta.autonym (the language's own name for itself, shown in the language picker).
2. Add the code to SUPPORTED_LANGS in public/i18n.js, to SETTINGS.language.values in lib/view.js, to I18N_LANGS in server.js, and as an <option> in the Language <select> of public/index.html.
3. Add the same code to LANGS at the top of test/i18n.test.js, then npm test — it checks that the new file has exactly the same keys as en.json (none missing, none extra) and the same {placeholders}, and that the server actually serves it.

🧭 How it works

memglow does two things: it polls a folder of Markdown notes (read-only) and it listens for activity — from a hook in your AI tool, from the MCP proxy, or from any script through the activity API. Both reach the browser over a server-sent events stream. That's it.

🚀 Quick start

One command sets everything up — notes folder, token, and the hooks of the AI tools it finds:

npx memglow init   # interactive; add --yes to accept everything
npx memglow        # start the viewer, then open http://127.0.0.1:4747

Just want to look at the demo?

git clone https://github.com/R0zumnik/memglow && cd memglow
MEMORY_DIR=./demo/memory node server.js     # the fictional demo memory
open http://127.0.0.1:4747                  # or just open it in your browser

Want to see it move without an assistant? Start the server with a token, then run the simulator:

export MEMGLOW_TOKEN=$(openssl rand -hex 32)
MEMORY_DIR=./demo/memory node server.js &
node demo/simulate.js 60             # add --counted to fill Memory cost as well

✅ MCP = seen when the tool goes through a memory MCP server (basic-memory, an Obsidian or filesystem server…). Plain file reads and edits of .md notes are seen directly where the tool's hooks expose them. Each hook mechanism was checked against the vendor's documentation; the link is in each adapter's README.

Writes from anything are already covered. memglow polls the notes folder: whenever a note's body changes on disk — whoever changed it — the note blooms, the camera goes to it and the journal says Note changed · Projects · Release notes · file (it also counts as a write in Memory cost). Hooks and the proxy add what the disk cannot tell: reads and searches, and which tool did it, from which machine, over which channel — e.g. Read · Projects · Release notes · laptop · hook · Claude Code.

🛠️ Install: memglow init

npx memglow init         # asks before each change
npx memglow init --yes   # non-interactive

It:

1. finds your notes — the default basic-memory project, ~/basic-memory, or your most recent Obsidian vault (--dir <folder> to choose);
2. writes ~/.memglow/memglow.config.json and a random token in ~/.memglow/token (mode 600);
3. detects your AI tools and proposes each hook (Claude Code, Codex, Gemini CLI, Cursor, Windsurf, Copilot CLI, Cline). Every file it changes is backed up first (<file>.memglow-backup), existing entries are kept, a file it cannot parse is left untouched;
4. proposes to put the MCP proxy in front of Claude Desktop's memory servers;
5. proposes to add memglow's built-in memory rules to the instruction file of each tool installed above that does not go through the MCP proxy (CLAUDE.md, AGENTS.md, GEMINI.md, …), in a replaceable block — default yes when interactive;
6. asks the same questions as the page's first run: which AI tools you use (several are fine; the detected ones are proposed), whether to turn the optional assistant on, and with which provider(s) and model. An API key can be typed there without echo (it goes to ~/.memglow/assistant-api-key-<provider>, mode 600) — or skipped, to set the variable or use the page later. --yes asks nothing and keeps the previous behaviour.

| Option | Meaning | |---|---| | --yes, -y | accept every proposal (non-interactive) | | --dir <folder> | notes folder | | --port <n> | viewer port (default 4747) | | --agents <list> | claude-code,codex,gemini,cursor,windsurf,copilot,cline, all (default: every detected tool) or none | | --wrap-mcp | with --yes: also wrap Claude Desktop's memory MCP servers | | --write-rules | with --yes: also add the built-in memory rules to CLAUDE.md/AGENTS.md/GEMINI.md/… (interactive: asked, default yes, regardless of this flag) | | --clients <list> | the AI tools you use (claude-code,codex,gemini,cursor,windsurf,copilot,cline,chatgpt,other-mcp or none), without asking | | --docker | also write ~/.memglow/docker-compose.yml and .env — with your first-run choices as variables, and the key lines commented out (no key is ever asked or written for Docker) |

Undo: memglow uninstall removes exactly what init added — hooks, the Cline script, MCP wrappings — and nothing else, even if you edited those files since. --restore-backups puts the original files back instead; --purge also deletes ~/.memglow.

Then start the viewer (npx memglow) and restart your AI tools.

🤖 Hooks by hand

Prefer to edit config files yourself? Each adapter has a README with the official mechanism, its source, and a ready-to-paste config snippet. For Claude Code, for example, add to ~/.claude/settings.json:

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "mcp__.*|Read|Write|Edit|MultiEdit",
        "hooks": [{ "type": "command", "command": "node /path/to/memglow/adapters/claude-code/hook.js", "timeout": 5 }]
      }
    ]
  }
}

and store the server's token: mkdir -p ~/.memglow && printf '%s' "$MEMGLOW_TOKEN" > ~/.memglow/token && chmod 600 ~/.memglow/token.

Adapter settings (environment of the AI tool, else ~/.memglow/memglow.config.json):

| Variable | Default | What it does | |---|---|---| | MEMGLOW_URL | http://127.0.0.1:4747 | where memglow runs | | MEMGLOW_TOKEN / MEMGLOW_TOKEN_FILE | ~/.memglow/token | the server's activity token | | MEMGLOW_MEMORY_DIR | from memglow init | plain file reads / edits count only for .md files in this folder | | MEMGLOW_MCP_SERVERS | basic-memory,memory,obsidian,notes,filesystem | MCP servers that count as "memory" | | MEMGLOW_MACHINE | short hostname | label for this machine in the journal (e.g. "laptop"); also settable as machine in ~/.memglow/memglow.config.json |

Every adapter answers its tool at once, sends the event from a detached process that gives up after 3 s, prints nothing else and exits 0: memglow being down never slows your assistant.

The v0.1 Claude Code hook, hooks/memglow-activity.js, keeps working unchanged (it also reads MEMGLOW_MACHINE, same default).

📡 Activity API

Any program can light notes up:

curl -H "Authorization: Bearer $(cat ~/.memglow/token)" -H 'Content-Type: application/json' \
  -d '{"type":"read","ids":["alice"],"source":"my-agent"}' http://127.0.0.1:4747/api/activity

type is read, search or write; ids are note names or paths (only existing notes are kept); source is the tool shown in the journal (each line reads action · group · note · machine · channel · tool, e.g. Write · Projects · Release notes · laptop · hook · my-agent — machine and channel are optional extras, v0.4: a short per-sender label and how the event got there — hook, mcp-proxy, file or api; an event without them shows exactly as before). durationMs (optional, v0.4, sent by the MCP proxy) is the memory server's response time for that call, used by Memory engine speed; a value that is not a number from 0 to 600,000 is ignored. Full reference with Python and Node examples: docs/api.md.

🔌 MCP proxy

For MCP clients without hooks (Claude Desktop, Continue, Roo Code…), put the proxy in front of the memory server. It reports note names only, and relays the server's answers — with, if you want, a few levers that make the assistant find faster and read less. It also delivers memglow's built-in memory rules to the wrapped server's initialize instructions, on by default, independently of every lever below.

"basic-memory": {
  "command": "node",
  "args": ["/path/to/memglow/mcp-proxy/memglow-mcp-proxy.js", "--name", "basic-memory", "--", "uvx", "basic-memory", "mcp"]
}

Streamable HTTP servers too: memglow-mcp-proxy --upstream http://127.0.0.1:8000/mcp --listen 127.0.0.1:8765. Tool-name mapping is configurable. Details: mcp-proxy/README.md.

Advanced: lever by lever

Most people never touch these — the 5-minute start profile is the default. Levers 2, 3, 8, 12, 13 and 18 (searchDetails, suggestions, alreadyLoaded, indexHint, deltaRead, sessionBudget) were removed in 0.6.0 and are not listed; tools.profile and stateView are described above.

Token-saving and speed levers (v0.4). The proxy annotates the memory server's answers — never your notes, which it only reads. Levers 1-3 only add a short block before or after the server's own content; 4, 5 and 8 may replace a read answer, so they are off by default; 9 (multiQuery) replaces a search call's one request/response pair with several upstream calls merged into one, so it is its own case (see below). searchDetails and suggestions (2 and 3) were on by default through 0.4.2.1b and are gone since 0.6.0; measured with the free replay harness (bench/README.md) and against a real 2-day usage log, they only added delivered tokens without a measurable upside, so stage 0.4.2.2 turned them off by default too (shortened either way, for whoever turns them back on). sizeWarning and multiQuery are the two levers on by default: the first is a single short line, once per large note per session, that plausibly prevents a wasted call; the second genuinely removes both calls and tokens on a real usage log (stage 0.4.2.2b — bench/README.md).

| # | Lever (proxy key / variable) | Default | Effect | |---|---|---|---| | 1 | sizeWarning / MEMGLOW_PROXY_SIZE_WARNING | on | ⚠ memglow: this note is ≈N tokens (threshold T)… before a large note, or after a write that makes it large — suggests a split within the same theme. Once per note and session. | | 4 | dedupe / MEMGLOW_PROXY_DEDUPE | off | An unchanged note re-read in the same session → a short "unchanged, ≈N tokens saved" notice. | | 5 | toc / MEMGLOW_PROXY_TOC | off | A large note → its outline with ≈tokens per section first; then one section on demand. | | 6 | archiveHint / MEMGLOW_PROXY_ARCHIVE_HINT | off | A search that finds nothing in the live memory (no result, or only archive notes) → memglow: nothing found in the live memory — the archive summary lists: … with the titles of the archived sections that match the query (never their text). | | 7 | hideUnsupportedTools / MEMGLOW_PROXY_HIDE_UNSUPPORTED | off | Hides, from tools/list and per client session, the tools a config table marks unsupported for that client — default: basic-memory's search/fetch (its ChatGPT-only adapters) hidden from any client that is not OpenAI's MCP client. A client that calls a hidden tool anyway is relayed unchanged; one unrecognised client is never filtered. | | 9 | multiQuery / MEMGLOW_PROXY_MULTI_QUERY | on | A search call carrying memglow_queries (2-4 extra phrasings, advertised in tools/list) is sent upstream as ONE call per phrasing, sequentially, the original first — instead of a separate model turn per phrasing. Hits merged, deduped by note id (found by more phrasings ranks higher), capped to one call's usual result count, returned as ONE result (the server's own hit blocks when safe, else a compact listing); any later phrasing's failed call fails the whole thing open to the first phrasing's own result. | | 10 | aliases + learnAliases / MEMGLOW_PROXY_ALIASES + MEMGLOW_PROXY_LEARN_ALIASES | on (since 0.4.2.5) | learnAliases (recording): a search followed within 2 minutes by a single-note read of a note NOT in its results teaches that search's significant words as aliases of it, locally, nothing ever sent anywhere. aliases (using it): a LATER search sharing ≥ 2 learned aliases of a note (or 1 seen ≥ 2 times) gets that note added at the top, in the upstream's own row shape when safe. Independent switches. On by default since the harness learned to count a dropped retry call, not just raw tokens (0.4.2.5) — see that stage below. | | 11 | negativeCache / MEMGLOW_PROXY_NEGATIVE_CACHE | off | A search not followed by any read within 2 minutes in the same session (or superseded by another search/write first) is remembered, locally, as "futile" for the memory's current state. A LATER search with the same significant words, while nothing has changed since, gets one line prepended: memglow: this search found nothing you used last time (<date>); the memory has not changed since. The results themselves are always still relayed right after — never hidden. Off by default: a clear win on its own dedicated fixture (a dropped retry call), but a real, unmodelled cost on bench/replay-heavy.jsonl (a naturally recurring search gets the hint with no call saved there) — see 0.4.2.6 below. | | 14 | duplicateHint / MEMGLOW_PROXY_DUPLICATE_HINT | off | After a write_note (never edit_note/move_note) whose title already names an existing note: memglow: a note with this title already exists: [[<id>]] — this write_note may replace or duplicate it; prefer edit_note. A title close to (but not matching) an existing note's id/label/description gets up to 2 candidates instead, with the same "prefer edit_note" suggestion. Checked before the write reaches the server, so the note being created is never mistaken for its own duplicate; same note never hinted twice per session. Advisory only — never blocks the write, never changes its arguments. Off by default: a pure, unconditional add, same bucket as searchDetails/suggestions/archiveHint/indexHint — see 0.4.4.1 below. | | 15 | slugHint / MEMGLOW_PROXY_SLUG_HINT | off | After a successful write_note (never edit_note/move_note) whose title is not a kebab slug (lower-case ASCII words joined by -), or that lands directly in the notes root (directory empty, / or memory): memglow: title "Chantier eau cave Choisy – état au 2026-10-11 soir" is not a kebab slug — prefer "chantier-eau-cave-choisy-etat-au-2026-10-11-soir" in a memory/<folder>/ directory (title = kebab slug, file = slug.md). The suggested slug is the file name --kebab-filenames gives (accents transliterated). Advisory only — never blocks the write, never changes its arguments. Off by default: a house style (title = kebab slug, file = slug.md, inside memory/<folder>/), not a general rule. | | 16 | hubHint / MEMGLOW_PROXY_HUB_HINT | off | For a memory that uses hub-and-spoke notes (a hub lists its parts under a ## Parts heading, and/or a part declares itself with frontmatter part_of/parent): an edit_note append/prepend/insert-before/insert-after, or a write_note overwrite, that adds more than hubHintTokens (default 400) tokens of new content to a note that HAS parts gets one advisory line: memglow: "<hub>" is a hub — add detail to one of its parts instead: [[part-a]] (topic), [[part-b]] (topic)…, parts ranked by shared significant words with the added text, best match first. Same hub never hinted twice per session. Advisory only — never blocks the write. Off by default: useful only to a memory that actually follows this convention; see docs/hub-and-spoke.md. | | 18 | orphanHint / MEMGLOW_PROXY_ORPHAN_HINT | off | After a write_note that creates a BRAND NEW note (never an edit, never an overwrite of a note that already existed) whose id, once written, memglow's own graph finds no link to or from (either direction — a dangling [[future-note]] elsewhere in the memory counts once this write resolves it): memglow: note [[<id>]] links to nothing and nothing links to it — add an "Up: [[hub]]" line or list it in its hub/index, or it will float alone in the graph. The index note never qualifies. Same note never hinted twice per session. Advisory only — never blocks the write, never changes its arguments. Off by default: same bucket as duplicateHint/slugHint/hubHint — a pure, unconditional add on the one note it fires for. | | — | indexWarning / MEMGLOW_PROXY_INDEX_WARNING | off | The index note read while above indexWarningTokens (default 2,000): ⚠ memglow: the index note … is loaded at every session — suggests trimming it. Once per session. |

Levers 4, 5 and 17 (stateView) change what the assistant receives: measure answer quality before enabling 4 and 5. Adding "memglow_fresh": true always brings the full note back; repeating the same read works too. Configuration (memglow.config.json → "proxy": {…}), examples and the exact rules: mcp-proxy/README.md.

🧠 MCP server (read-only)

A second, separate MCP server — not the proxy above — that lets your assistant ask memglow questions about its own memory, instead of only being watched by it: which notes are too large, what to read first about a topic, what something costs to read. It starts entirely on its own (no viewer, no network, nothing else to run first) and never writes anything — not the notes, not even memglow's own counters. Like the proxy, it adds memglow's built-in memory rules to its own initialize instructions, and offers them again as an MCP prompt named memory-hygiene (prompts/list / prompts/get).

"memglow": {
  "command": "npx",
  "args": ["-y", "memglow-mcp"],
  "env": { "MEMORY_DIR": "/path/to/your/notes" }
}

Works the same way in Claude Code (claude mcp add memglow -- npx -y memglow-mcp), Cursor (.cursor/mcp.json, same command/args/env) or any MCP client that can run a stdio command. Locally, straight from the repo: node mcp-server/memglow-mcp.js. Configuration is the same as the viewer's (MEMORY_DIR, memglow.config.json, MEMGLOW_DATA_DIR, MEMGLOW_LARGE_NOTE_TOKENS, splitChunkTokens — see Configuration); if MEMGLOW_DATA_DIR holds the viewer's activity counters, the tools below use real 7-day read counts, otherwise they say so plainly instead of guessing. An empty or missing notes folder is not an error: the tools just answer "no notes found".

| Tool | Arguments | What it returns | |---|---|---| | memory_health | (none) | Notes over the large-note threshold, the costliest notes to read over 7 days and the notes never read in 30 days (both only once enough activity history exists), the size of the index note, and the always-loaded cost (index + alwaysLoaded files, × sessions per day). | | split_plan | note | A deterministic split of one note along its ## sections (same rule as the Memo
