Computer use
An AI assistant that uses your computer.
Stella is a personal AI assistant that can use your computer for you. On Mac and Windows it sees your screen, clicks, types, opens apps and moves between windows to finish real tasks in the apps you already use, while you keep working in another window. Free.
Works in your real apps
No integrations to set up. If you can do it with a mouse and keyboard, you can ask Stella to do it.
Keeps you in the loop
Stella acts when you ask, shows what it is doing, and reports back in the same chat when it is done.
Browser, files and terminal too
It can also browse and fill in forms, organise files and run commands, picking whichever is fastest.
Questions.
Is there an AI that can use my computer for me?
Yes. On Mac and Windows, Stella can see your screen, click, type, open apps and move between windows to finish a task in the apps you already use, like booking a flight and putting it in your calendar. It acts when you ask it to, and on a Mac you grant the usual screen and accessibility permissions first.
Can Stella browse the web and fill in forms?
Yes. Stella can search, read pages, click through sites and fill in forms in a browser, then bring the result back to your chat.
Is Stella free?
Yes. The Free plan is $0, with no credit card and no trial. Go is $5 a month for 10× more usage. Pro is $15 a month for the highest limits, image, video, 3D and voice generation, and multiple agents working at once.
Does Stella work on Linux, Arch or Omarchy?
Yes. Stella has a Linux desktop app with a one-line installer, packaged for Arch and Omarchy as well. On Linux it works with your files, terminal, browser and chat. Clicking and typing inside other desktop apps is on Mac and Windows today.
