File-first knowledge base for humans and AI agents — self-hosted Markdown notes with a web editor and a built-in MCP server.
One knowledge base, so your AI starts with context. Your agents, Markdown, and editor — in one container.

Notarium is a self-hosted knowledge base built on plain Markdown. A person works in the web editor; an AI agent works through a built-in MCP endpoint — the same notes, the same permissions, the same version history. It runs on your own server as a single container: no external database, no queue, no separate search service.
The .md files are the source of truth. The search index, the link graph and the rest of the derived data are rebuilt from them — take the folder and walk away, and you still have your notes.
That structure is also what makes it worth pointing an agent at. A folder of Markdown gives an agent text; a knowledge base gives it links, a graph and search, so it retrieves the context for the task instead of dumping everything into its window.

The same knowledge base in every shot: a self-hosted developer's notes about the machine and the services they run. Every picture here is generated from it by make footage, never cropped by hand.
The editor. The note above, as the .md file it actually is — CodeMirror over your own Markdown, with the rendered result a keystroke away.
One history for you and your agent. v3 — your agent sits in the same revision chain as v2 — you: same write path, same permissions, same word-level diff, same rollback. This is the claim the whole project rests on, so it
