It's a Chrome extension that captures conversations and transfers them between platforms with one click. Everything stays in IndexedDB, no external servers.

Chrome Web Store if you want to try it: https://chromewebstore.google.com/detail/relai/inkojohbljaag...

Known limitations: long conversations can lose formatting, and platform DOM changes will break extractors until I patch them. Built with vanilla JS, no frameworks, no build step.

Happy to answer questions about the implementation.
