Intelligence that runs on your hardware, and answers to no one else.
Anthrena builds offline-first AI and analytics — nano language models, a Rust compute engine, and decision intelligence platforms that work inside your browser, on your desktop, behind your air gap. Your data never leaves. Your answers never wait.
Every important decision now happens in an arena crowded with AI — but almost all of it lives in someone else's cloud, speaks someone else's language first, and treats your data as its raw material.
We think the arena belongs to the human standing in it. So we build the entire stack — models, compute, platforms — to run where you are: a 19 MB model inside a desktop app, a dataframe engine compiled to your browser, an analytics platform that opens on a laptop with no internet at all.
AI that answers to you.
Sovereignty is a feature
For a power utility, a public-sector bank, or a hospital, "send your data to our API" is not a product — it's a dealbreaker. We design for the air gap first, and everything else inherits that discipline.
Small models, sharp jobs
A 50M-parameter model that knows your schema beats a trillion-parameter model guessing at it. We train nano language models from scratch — our own architecture, our own tokenizer, our own infrastructure.
Compute you can audit
Answers should come from deterministic computation, narrated by language — never the reverse. Rust and WebAssembly give us math that is fast, verifiable, and runs anywhere a browser does.
One vertically integrated stack, from silicon-adjacent to boardroom.
Two products, one philosophy: intelligence that lives where your data lives.
