chatbridge

ChatBridge solves a specific annoyance: if you have a conversation with ChatGPT, Claude, or Gemini and want to continue it in a different AI tool, there is normally no way to carry that context over. ChatBridge takes a public share URL from one of those three conversation types and converts it into a clean, provider-neutral page that other AI tools can read, so you can paste the new link elsewhere and pick up where you left off.

The workflow is simple: paste a public ChatGPT, Claude, or Gemini conversation URL into ChatBridge, it reads the shared conversation and builds a portable page from it, and you copy that new URL wherever you want to continue the conversation. The tool also lets you export a conversation as Markdown, and the person who created a page can delete it later from the same browser they made it in.

On privacy, ChatBridge only processes a public conversation to build the requested page, and states it does not use the content for profiling, advertising, analytics, or model training. Generated pages are public to anyone who has the link, a deletion key lives only in the creator's browser, pages are excluded from search engine indexing, and conversations are automatically deleted after 30 days. Claude imports currently go through a service called Jina Reader as a transport step, and the README asks users not to submit secrets or conversations they are not allowed to share.

To run it locally you need Node.js 22 or newer, npm, and a PostgreSQL database; the app creates its own database table and expiry index automatically on first run. It is built with Next.js App Router, React, the Motion animation library, and Neon serverless Postgres, and it can be deployed to Vercel with one click, including a daily cron job that cleans up expired conversations. The project is released under the MIT license.
