The Problem

Every AI switch costs you minutes.
Multiply that by your whole day.

You use multiple AIs because each one is better at different things. But every time you switch, you start from scratch. You waste minutes re-explaining your project, your stack, your decisions. The AI doesn't know you. Again.

That friction kills momentum. And copy-pasting walls of text between chat windows is not a solution.

Simple by design

Sync in 3 clicks

1

Open

Click the Universal AI Sync extension icon in your Chrome toolbar while on your AI conversation page.

2

Select

Pick your source AI (where the conversation lives) and the destination AI (where you want to continue).

3

Sync

Sync your full conversation — including code blocks and key context — transfers automatically.

Built for power users

Everything your workflow needs

Never re-explain yourself

Full conversation history transfers including AI responses and code blocks. The destination AI picks up mid-thought.

Syncs in seconds

Smart chunking handles conversations. Long threads sync automatically in rapid sequential parts. Premium Sync File bypasses text limits for massive threads 10x faster.

100% private

Everything runs locally in your browser. No servers, no accounts, no conversation data ever leaves your machine.

Works with all major AIs

ChatGPT, Claude, Gemini, and Copilot. Switch between any combination in any direction.

Clean context, not noise

Built-in AI filler stripping removes “Great question!” fluff before transfer. Only the meaningful content moves.
