Tensai

Tensai とは？

Switch from Claude to ChatGPT and your prompt box is already filled - the decisions, open questions, and code from your last exchange, compressed locally. No button, no popup, no icon to click. Every other context-bridge extension makes you trigger the handoff manually; Tensai starts the moment you switch tabs. It also notices when Claude is nearing its context limit and pre-fills the handoff before you lose the thread. No cloud, no API key, no telemetry.
