Copy a thread from ChatGPT, Claude, or Gemini and continue it in another provider — without retyping the chat. How it works ## Extract. Choose. Continue. - 01 ### Extract the current chat Open a conversation on ChatGPT, Claude, or Gemini. Click the ContextSwitch icon and extract the thread. - 02 ### Pick a destination Send the full conversation, the last 10 messages, or the last 20. You choose how much context travels. - 03 ### Keep talking ContextSwitch opens a new chat and pastes the thread into the composer. You send the message yourself. Providers ## Works with the chats you already use Portable files ## .chatbridge Export a conversation as a local JSON file. Import it later and continue in any supported provider. ChatBridge is an open format — the file stays on your machine. Privacy ## Nothing leaves your browser ContextSwitch does not send conversations to a ContextSwitch server. Transfer reads the current page and inserts text into the destination composer. The extension only requests access to ChatGPT, Claude, and Gemini. Install ## Get it for your browser Listings go live when the Chrome Web Store and Edge Add-ons reviews finish. This page will point at those URLs.
