Show HN: Relai – Share context between AI assistants, 100% local
kpolevoy1 Thursday, February 05, 2026
Hey HN — I built this because I switch between Claude, ChatGPT, Gemini, and Perplexity constantly and got tired of re-explaining context every time.
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.
