Sync, mirror, and export conversations between ChatGPT, Claude, and Gemini in real-time. Universal AI Sync lets you instantly move any conversation from one AI to another — no copy-pasting, no starting over.
How it works Open your AI tabs (ChatGPT, Claude, Gemini, or Microsoft Copilot), click the extension, pick a source and a destination, and hit Sync. The extension reads your full conversation history, cleans it up, and injects it into the destination AI so it understands the full context — as if it had been there from the beginning.
Two sync methods
Supported platforms ✓ ChatGPT (chat.openai.com / chatgpt.com) ✓ Claude (claude.ai) ✓ Google Gemini (gemini.google.com) ✓ Microsoft Copilot (copilot.microsoft.com)
Free vs Pro The free plan includes unlimited text-based sync and one file sync every 5 hours. Upgrading to Pro removes the cooldown for unlimited file syncing.
Privacy All conversation processing happens locally in your browser. Your messages are never sent to any third-party server — only the license validation and payment flow communicate with our backend.
