De-Weaponize

A Firefox WebExtension that rewrites harsh or aggressive text on web pages into a tone of your choosing. Uses Relational Frame Theory as its analytical lens — instead of swapping vocabulary, it detects and reshapes the underlying frames (opposition, hierarchy, comparison, causation, perspective) to match a target tone.

Works with multiple LLM providers: Claude, Codex, Gemini CLIs, Ollama, OpenAI API, and Anthropic API.

Features

• Auto mode — toggle ON in the sidebar to automatically detect and rewrite aggressive passages as you browse
• Manual mode — select any text, right-click, and choose De-Weaponize — Rewrite selection
• 11 tone presets — de-weaponize, neutral, casual, formal, warm, ELI5, humorous, academic, concise, poetic, and more
• 3 sensitivity levels — low, moderate, high
• Click to toggle — click any rewritten passage to switch between the original and adjusted text
• Multilingual — preserves the language of the original text
• Multiple providers — local proxy (Claude, Codex, Gemini CLIs, Ollama, OpenAI, Anthropic APIs) or direct API calls from the browser
• Sidebar UI — persistent sidebar panel with health indicator, onboarding wizard, and auto-save
• Options page — full-tab settings for provider, API key, model, proxy URL, token management, and debug log
• Token auth — shared secret between extension and proxy for security
• Smart error handling — contextual error messages with retry buttons

Quick Install

1. Install the proxy

npm install -g deweaponize

Or run without installing:

npx deweaponize

Requirements: Node.js 18+ and at least one LLM backend (see below).

2. Load the extension in Firefox

Clone the repo and load it as a temporary add-on:

git clone https://github.com/nicopi/deweaponize.git

1. Open about:debugging#/runtime/this-firefox
2. Click Load Temporary Add-on
3. Select manifest.json from the cloned directory

Usage

Quick start

1. Install the extension (see above)
2. Click the De-Weaponize icon in the toolbar or press Ctrl+Shift+U to open the sidebar
3. If using the local proxy, follow the setup instructions shown in the sidebar
4. Toggle ON and browse normally — text is blurred until processed

Local proxy (default)

The proxy supports multiple backends. Use --list-backends to see all options.

# CLI backends (use your existing subscription/installation)
deweaponize                                            # Claude CLI (default)
deweaponize --backend codex                            # OpenAI Codex CLI
deweaponize --backend gemini --model gemini-2.5-pro    # Google Gemini CLI

# API backends (require API keys via environment variables)
deweaponize --backend ollama --model qwen2.5:7b        # Ollama (no key needed)
deweaponize --backend openai --model gpt-4o-mini       # OpenAI API
deweaponize --backend anthropic                        # Anthropic API

# Options
deweaponize --port 7880                                # Custom port
deweaponize --token <TOKEN>                            # Token auth (get from Settings)
deweaponize --list-backends                            # Show all backends

Custom binary paths and API base URLs via environment variables:

CLAUDE_PATH=/usr/local/bin/claude deweaponize
CODEX_PATH=~/.local/bin/codex deweaponize --backend codex
OPENAI_BASE_URL=https://openrouter.ai/api/v1 deweaponize --backend openai

The sidebar shows a green dot when the proxy is connected and auto-detects when it comes online.

Direct API (no proxy)

Open the Settings page (link in sidebar footer), set Provider to Anthropic API or OpenAI API, and enter your API key. The OpenAI provider also supports a custom base URL for OpenRouter, Azure, and other compatible APIs.
