Matrix

Ask a thousand pages a question. On a phone, offline.

Matrix reads whole document collections, answers with the exact sentence that proves it, and draws who-relates-to-what as a graph where every link carries its quote. It runs on a Mac or an iPhone — the documents never leave the device.

See how it works
Matrix knowledge graph: thousands of entities and relations extracted from a company's annual report, each link labelled with its relation type.
A real run: one public annual report became 4,385 entities and 1,919 relations — every link backed by a quote from the text.

For people building with AI agents

An AI that maintains my software — and has to ask first.

It reads support forums, writes the fix and passes checks no model can talk its way through. Every release, merge or forum reply then waits for one word from my phone.

How the maintainer loop worksA scout reads forums and reviews, a worker writes a fix on its own branch, deterministic checks verify it, and nothing is released, merged or posted until the owner approves that single action from his phone.Scoutreads the forumsWorkerwrites the fixChecksno model involvedGate„ja“one word per action,from my phonethe model only ever proposes —it never ships anything itself
