synphant

Synthetic memory for AI. Synphant gives Claude (and other LLMs) long-term memory that persists across conversations.

Install

npm install -g synphant

Setup

# Authenticate
synphant login

# Configure Claude Code hooks and MCP server
synphant setup

# Verify everything is working
synphant setup --check

Restart Claude Code after setup.

What Gets Configured

synphant setup adds three things to your Claude Code settings:

1. Ingest hook — automatically archives every conversation turn
2. Recall hook — retrieves relevant memories before each prompt
3. MCP server — gives Claude explicit memory tools (remember, recall, trace, etc.)
