MetafeatureMuse for Mac
Meta's personal AI agent now runs as a Mac app that can act inside your native files, mail, messages, calendar, and notes.
Details
- Muse interacts with files, mail, messages, calendar, and notes inside their native macOS applications rather than through a separate chat surface
- Access to each app is opt-in, and Meta says the agent asks for approval before performing sensitive actions
- Follows the mobile and web launch of Muse earlier in September 2026, which reached the top of the U.S. App Store
- Downloadable at ai.meta.com/muse/download/
Best for
Handing off desktop work that spans apps, where the agent needs to open things rather than be shown them.
When to use it
The task lives in local Mac apps and copying it into a chat window would lose the context.
Who benefits
Mac users who already tried Muse on mobile or web and want it acting on their own machine.
