How to use Muse on a Windows computer: use the web version, with no software to install. As of late October 2026, Muse has not released a native Windows app; Microsoft said at its October 7 event only that it is "coming soon," with no date given. Any website claiming to offer a Muse installer or a .exe download should not be touched — what you install may be fake software. The web version and the phone app use the same Meta account, and tasks and memory carry across, so switching devices does not mean starting over.
How to get in on each device, in one table
| Device | How to use it | What to watch for |
|---|---|---|
| Windows computer | Open muse.ai in a browser and sign in | No download needed; make sure it is the official domain |
| Mac | The native Mac app from the official download, launched September 18, 2026 | It can read and write files, mail, and calendar only with your permission |
| iPhone, iPad | Find "Muse from Meta" in the App Store | Requires iOS 18.0 or later |
| Android phone | Find "Muse from Meta" in Google Play | Go by the device requirements shown on the store page |
| After connecting it in Muse, message it like a contact | Good for short tasks; return to the app or web version for complex work |
Starting on Windows is simple: open your browser, go to muse.ai, and sign in with your Meta account. If the page says your region is not yet supported, that is an account-region limit — switching browsers or using a proxy will not get around it, so first confirm you are in a supported region. The difference between the Mac app and the web version is mainly whether it can touch things on your computer: with permission, the Mac app can work inside local files, mail, and calendar, while web tasks run on Muse's own cloud computer — and the task record is the same in both. People on a work computer that cannot install software, or who only use it occasionally, should treat the web version as the correct entry point and not go hunting for a third-party installer just to have an icon.
