Kith - Your AI's memory, identical on every machine you own

by•
Kith gives you and your AI one shared memory. Your notes, saved tabs, and files live in a private, end-to-end-encrypted store that's identical on every device you own. Run kith serve and Claude Desktop or Cursor read and write the exact same local data over MCP. No account, no cloud, no server that can read it — pair a device with a short code.

I kept hitting the same wall: I'd build up context with Claude Code on my desktop, switch to my laptop, and the AI had no idea what we'd just done. My notes and files were scattered too. So I built Kith — one private memory that you and your AI both write to, identical on every machine you own. The part I'm most excited about: it's not a chatbot bolted onto storage. You run kith serve, and Claude Desktop or Cursor read and write the same local memory, tabs, and files you see in the app. Co-equal. No account, no cloud — devices pair with a short code and sync directly, end-to-end encrypted. Honest caveats: this is alpha. Builds are unsigned, and the crypto hasn't had an independent audit yet, so please don't trust it with anything sensitive. It's free and open source (MIT/Apache). I'd genuinely love feedback — especially from anyone running AI tools across two or three machines. What breaks for you?
