Sentient Os

Sentient OS is an open-source personal AI for your Mac. It understands the context of your life and work overnight, so you can hand off a task, draft the right reply in two taps, or wake up to useful work already prepared for your approval. Your own apps. Your logged-in browser. The stuff you were about to do yourself.

On-device understanding. Your choice of AI. Knowledge you own. We do the high-volume understanding on your Mac, keep your knowledge in ordinary Markdown files, and let you choose the model that puts it to work. A compatible local model can handle the rest of the inference too :)

the task is small. the briefing isn't.

Computer-use agents can already take on ambitious jobs. But look at the little chores scattered through your day: a half-filled application, a customer waiting for an update, receipts stranded across your inbox, another form asking for the same things about you.

First, explain what you're looking at. Who this person is. What you agreed last week. Which project the question is about. Where the relevant file lives.

At some point, doing it yourself feels quicker. So you do. Again.

Sentient does the catching up before you ask. Overnight, it builds a connected understanding of the sources you choose. By day, that knowledge and your screen give a short request somewhere to start. Click the notch: “finish this for me.” Sidekick picks up the task in your own apps, with its own cursor, while you carry on.

Think of a butler who already knows what's going on, and happens to live in your Mac's notch. A rather useful place to keep one :v

a little handoff. a lot off your plate.

sidekick · when you ask

Click the notch, tap your right Command key to type, or hold it to speak. Sidekick has its own mouse cursor, so it can use your apps while you keep using your computer. It brings your screen and knowledge into the task, clicking, typing, attaching files and moving between windows on your behalf.

For your life:
