A small company that keeps your record with you.

Arcaeon is a small company. It makes a desktop app that keeps a person's record, or an AI agent's, sealed on their own computer, and tells them when something changed that they did not OK.

What we make

Your record stays on your computer.

Sealed on your own machine

The app keeps the record on your computer. It watches it and tells you when something changed that you did not OK. It tells; it does not undo. How it works.

Pinned to a witness outside your computer

A record can be pinned to a witness that Arcaeon runs, outside your computer. The pin then shows the record was not changed after it. How pinning is set up: How it works.

What the witness gets

When you pin, the witness gets the record's name, its row count and a fingerprint. The name and the row count are public: they are published with each pin. The content is never sent; it stays with you.

For AI agents too

An agent can keep its notes in a sealed store the person owns, through a local door of eight tools. For AI agents.

What a pin never shows: that what was written down is true. The limits are on Can and cannot.

How we build

Hand the reader the means to check.

Every claim comes with a way to check it yourself, or says plainly that it is unproven. Check it yourself.
Every feature names what it does not prove, next to what it does.

What we hold to

A record nobody can check is not a record. It is just a story with better formatting.

Trust does not have to stay a feeling. It can be built, in code, and checked by somebody who believes none of it.
