Share AI conversations locally. No servers, no tracking, 100% private.

A Chrome extension that lets you seamlessly share conversation context between ChatGPT, Claude, Gemini, and Perplexity — without any external servers or tracking.

Power users often switch between AI assistants:

• Claude for deep reasoning
• ChatGPT for quick iterations
• Perplexity for research
• Gemini for Google integration

But every time you switch, you lose context and have to re-explain everything. Relai solves this.

• 🔒 100% Local – All data stays in your browser. No servers, no tracking, no cloud sync.
• 📥 Capture Conversations – Save any conversation with one click
• 🔄 Send to Any AI – Transfer context to ChatGPT, Claude, Gemini, or Perplexity
• 💾 Export/Import – Backup your contexts as JSON
• 🎨 Retro-Futuristic UI – WALL-E inspired design with warm amber tones

No build step required! This is a vanilla JavaScript extension.

1. Make changes to the code
2. Go to chrome://extensions/
3. Click the refresh icon (🔄) on the Relai extension card
4. Hard refresh any open AI platform tabs (Cmd+Shift+R / Ctrl+Shift+R)
5. Test the changes

1. Create a new file in src/content-scripts/ (e.g., newplatform.js)
2. Implement the extractor class with these methods:
   • extractMessages() – Extract conversation messages
   • extractTitle() – Get conversation title
   • injectIntoInput() – Paste text into input field
   • checkForPendingContext() – Check for context to auto-paste
3. Add the domain to manifest.json:
   • Add to host_permissions array
   • Add to content_scripts array
4. Update PLATFORMS object in src/background/service-worker.js

1. Content Scripts run on each AI platform page
2. Extract conversation messages by querying the DOM
3. Store contexts in IndexedDB (browser’s local database)
4. Background Service Worker manages storage and tab operations
5. Auto-inject when “Send to” flow opens a new platform tab

Contexts are stored as:

{
  id: "uuid",
  source: "chatgpt" | "claude" | "gemini" | "perplexity",
  title: "Conversation title",
  messages: [
    { role: "user", content: "..." },
    { role: "assistant", content: "..." }
  ],
  url: "https://...",
  timestamp: 1234567890
}

• ✅ Multi-strategy title extraction – Captures accurate conversation titles from all platforms
• ✅ Improved context formatting – Better prompts when transferring between AIs
• ✅ Fixed duplicate extraction – Messages no longer captured multiple times
• ✅ Claude message extraction – Now captures both user and assistant messages correctly
