Most AI tools have some memory now, but it's siloed to one app, stored as flat text, and not searchable by meaning.
I built a self-hosted semantic memory server that any MCP-compatible tool can connect to. Store a thought, search by meaning later — not keywords. Capture from your phone via a web form, or just tell Claude to remember something.
The whole thing is two Docker containers behind a reverse proxy. No Supabase, no managed anything. Your memories on your hardware.
Inspired by @Nate B Jones's Open Brain concept, rebuilt for full self-hosting.
