About MetaBrain

metaBrain is open-source local document memory for AI tools, coding agents, and humans, with searchable notes, metadata, tags, links, version history, and an optional local daemon. Give every agent one durable, searchable place for notes, source snippets, task context, metadata, tags, links, and version history. The quickest path is the `mb` CLI: initialize a local store, write a note, search it, and keep moving. The optional server is there later when several tools need concurrent access.

By the end of the day we had dashboards our whole team actually uses. You can redact PII at the SDK level before anything leaves your servers. Overage is billed at $1 per 10k events, and you can set a hard cap if you prefer strict budgets.
