Nabsun: open-source AI browser that works in your real tabs
Chromium/Electron browser with a built-in AI assistant that reads your open pages, compares across tabs, and acts inside your existing signed-in session.
Why it matters
MIT-licensed developer preview; runs a bundled local model, any cloud provider, or brings Codex/Claude Code into the browser - no copying context into a separate chat or replicating session state.
What you could build with it
Use it as the research front-end for radar runs: assistant reads docs/repos across tabs while you stay signed in.
