Install

You run it. Here is the real cost.

Self-hosting is not a preference here, it is the architecture — it is why there is no second tenant to leak to and why your files never move. It is also genuine work, so it belongs on the page rather than in a welcome email.

What you need

A machine that stays on — a NAS, a home server, a spare Mac. Docker and a Postgres. A markdown corpus you already keep, ideally in git.

What you get

The server and its index, a macOS desktop build and an Android build, and an MCP endpoint your agents can point at.

What you own

Backups. The vault's markdown is git-mirrored, but annotations and review state live in Postgres — if you do not back that up, they are not backed up.

Roughly the shape of it

A compose file, a database, a token, and the indexer pointed at your vault. Then the client, told where the server is. If that sentence reads as a normal evening, you are the person this beta is for.

The honest version

Right now this is not a one-command install. It is the single highest-leverage thing to fix, and it is the thing most likely to decide whether the beta works at all — if nobody completes the install, the funnel is the product and the annotation model was never the question.

So the beta is small and hand-held on purpose. You will get the artifact, the compose file, and me on the other end of a message while you stand it up.

Before you ask

Three things that put people off, up front.

It is a closed-source binary. You will be running software you cannot read against your entire corpus. The files stay markdown on disk and git-mirrored so you can verify what it did — but if closed source is disqualifying, it is disqualifying.
Backups are yours. Document bodies survive in your git mirror. Annotations, review state, pins and share grants do not — they are in the database, and that is your responsibility.
It is shaped like one person's workflow. The daily note, the templates, the review boxes — the mechanism is general, the defaults are not. For a handful of invited people who can be told that, it is survivable. It is the thing that stops being survivable later.

Still in?

That is genuinely the right reaction to have after reading this page rather than before.
