The AI context bridge for Claude and ChatGPT.
Switch tabs. The other side already knows.
Open Claude or ChatGPT - whichever model fits the thought in front of you.
Tensai quietly keeps the useful pieces together while you move to the other side.
The new conversation opens with the context it needs - not an empty page.
Tensai was built to make the distance between Claude and ChatGPT feel smaller. Not with more software. With less forgetting.
Move between Claude and ChatGPT without re-explaining the work already done.
Long conversations become focused context: goals, decisions, open questions, and the code that still matters.
Switch tabs and find Claude or ChatGPT prepared to continue instead of staring at a blank prompt.
Tensai fills the draft. You review it. You decide when anything is actually sent.
A live sense of Claude's context window as it fills - and a warning at 60% and 85% before it closes.
The settings page holds every captured turn. Export the session as JSON or Markdown when you need it.
The extension is intentionally small. The experience it enables is not. These are the artifacts of a handoff: Claude paired with ChatGPT, a context block written into the next conversation, and the settings that hold the session.
Tensai captures your conversation on Claude or ChatGPT, compresses it locally, and fills the other AI's draft box with a structured briefing when you switch tabs. You review it and press Send - Tensai never submits anything on your behalf.
Most AI-heavy work doesn't stay in one model. Claude reasons better, ChatGPT iterates faster. You end up with both open, manually copying context between them. That loop is lossy. Tensai keeps that context moving automatically, structured and local, so the other AI picks up exactly where you left off.
Completely free, no account, no API key. You just need a logged-in Claude tab and a logged-in ChatGPT tab - compression runs locally inside the extension.
No. Everything stays in chrome.storage.session, inside your browser, and clears when Chrome closes. No servers, no analytics, no network requests with your data.
Never. Tensai only fills the draft box. It does not touch the Send button under any condition.
Yes, fully bidirectional. Tensai captures turns from whichever AI you're talking to and can inject context in either direction - Claude to ChatGPT, or ChatGPT to Claude.
Tensai detects the limit automatically and fires a one-time handoff into your paired ChatGPT tab - your objective, decisions, open questions, and code - before you even switch. A toast on Claude shows a Switch now action.
Tensai restores it when you return. The handoff comes back in the paired tab so you can review and send it yourself.
If Enhanced Protection is enabled, Chrome shows this notice for new extensions until store reputation builds. Tensai is 100% local and serverless - simply click 'Continue to install'.
