AgentOS lives on your Mac and does the work there. You talk to it from your phone or your earbuds, the way you would talk to a person, and it checks with you before the risky steps.
An early version, for the Mac. Free and open source. No AgentOS account: Nova thinks with a Claude key you add once.
The March bill, €84.20, is attached.

AgentOS gives an AI agent the whole computer: it sees the screen, clicks, types and works on your files. You ask from your phone, the way you would ask a person. Nova does the work, tells you how it went, and stops to ask before the risky steps.

Good morning, Alex.
Talk to Nova…
Nova is asking
Everything looks good. Can I deploy to production?

Alex is out for a run. Nova is at home, on the Mac.

Your screen goes dark and calm. Only Nova is left, with one line about what it is doing. Move the pointer and you can take back control at any moment.
Rather keep working? The side panel keeps Nova at the edge of your screen instead.
With earbuds in, Nova asks out loud and you simply answer, phone in your pocket. An Apple Watch companion is being built, for the same question on your wrist.
Speech runs on your phone by default, with no key.
Before a step it knows is risky, such as paying, deleting files or publishing, Nova stops and asks, with a picture of what it sees. Stopping is always one tap or one word.

Try it: the buttons work.
An agent that can use your whole computer can be misled by what it reads. A web page, an email or a file can try to steer it. Asking first reduces that risk; it does not remove it. Start with “Ask before every change”, and loosen it once you trust it.
AgentOS has no account and no server of its own. Your devices talk to your computer, and your computer talks only to the services you chose: the model that thinks, and a voice if you add one.
A device gets in only with the one-time code shown on your computer. At home, the connection is encrypted with your computer’s own certificate, checked every time.
API keys are kept in one file only you can read, and never handed out, not even to your phone.
Every line is on GitHub. Read it, change it, run it yourself.
AgentOS is at version 0.1. The whole loop works — you ask, it works, it asks back, you answer — and some edges are still rough.
AgentOS is an early version, for the Mac. Download the app, open it, and answer a few questions. It is free and open source.
Nova thinks with Claude, so you will need a Claude key, added once. You get it from Anthropic, who bill what Nova uses. AgentOS itself is free.
