Matrix LLM · iPhone, iPad and Mac

Ask your documents. On your Mac or iPhone, offline.

Every answer comes with the exact passage it is based on. And Matrix maps who relates to what into a knowledge graph, with a quote behind every link. The models can run entirely on your device: compact ones on the iPhone, large ones on the Mac.

Matrix knowledge graph extracted from a public annual report: hundreds of entities linked by typed relations.
Matrix on an iPhone: a question about a sample contract, answered by Apple's on-device model, with the cited passage underneath.
Behind: a knowledge graph from one public annual report. In front: Apple's model answers on the iPhone, with the passage it used.

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
Inside the loop
