Your context.Never lost.
Tensai syncs your conversation between Claude and ChatGPT in real time. Switch tabs mid-session or hit a context limit - the other AI picks up exactly where you left off.
Pair your tabs
Open Claude and ChatGPT side by side. Click pair in the Tensai popup - done. No accounts, no setup.
Tensai watches
Every completed turn is captured and compressed locally in the background. You keep chatting - Tensai keeps track silently.
Seamless handoff
When Claude hits its context limit, Tensai pre-fills ChatGPT's draft box with your compressed session - ready to send the moment you switch tabs.
Bidirectional context sync
Every turn captured on Claude flows to ChatGPT and vice versa. Switch platforms mid-conversation without losing a single thought.
Smart conversation compression
Local algorithmic compression distills your conversation to its essence - goals, decisions, open questions, code - entirely inside your browser. No API calls, no cloud.
Automatic context handoff
Switch tabs and Tensai pre-fills the other AI's draft box with a structured briefing. When Claude hits its limit, the handoff fires automatically - you never lose your thread.

Everything you need to know before installing. Nothing more.
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.
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.
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.
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.
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.
Never. Tensai only fills the draft box. It does not touch the Send button under any condition.
A local algorithm built into the extension extracts your objective, decisions, open questions, and code, then trims the result to a 2,500-token handoff - entirely inside your browser, no internet needed.
