AI Context Sync: Prompt Manager & Snippets

AI Context Sync stores reusable text snippets in your browser and inserts a selected snippet into the chat input of ChatGPT, Claude, Gemini, Perplexity, or Copilot when you press a keyboard shortcut.

If you run more than one AI model a day and keep a scratch document of prompts you copy and paste from, this replaces that document. Press Ctrl+Shift+K (Cmd+Shift+K on Mac), search your snippets, and the text lands in whichever chat you're in, filled in with your project's variables if the snippet uses them.

Why this exists

Most prompt managers ask for a signup before your first insertion, or bind to one AI provider. This one doesn't. There's no account, no server, and no upload: your prompts are stored in Firefox's own extension storage and sync through Firefox Sync exactly like your bookmarks do, if you have Sync turned on. If you don't, everything still works, entirely locally.

Features

• One keyboard shortcut opens a searchable picker over any supported chat input
• Variables like {{name}} or {{project}} fill in automatically per project profile
• Cross-device sync through Firefox Sync, with automatic local fallback if you ever hit the sync quota; nothing is ever dropped or truncated
• Import and export your whole library as a single JSON file
• A local diagnostics log you can copy into a bug report, no analytics, ever
• Zero outbound network requests, enforced automatically on every release and checked again before every submission, not just claimed in this description
