In brief

Meta's AI assistant can now control files, messages, and calendar on your computer, joining a race to dominate consumer AI agents. AI agents that can take actions on your computer are becoming the next battleground for tech companies competing to replace traditional apps. Originally reported by TechCrunch.

Meta's Muse comes to Mac

Meta's AI assistant Muse is now available on Mac, letting it interact with your files, messages, calendar, notes, and mail directly in their native apps.

“your agent can now get stuff done right on your computer, files, messages, calendar, notes, all of it.”

You control what it can access

Muse operates on an opt-in basis, and always asks for approval before performing sensitive actions on your Mac.

“you're in control of what it can access, and it always asks before doing anything sensitive.”

The desktop launch comes as major tech companies race to dominate consumer-facing AI agents, which many believe will reshape computing, apps, and software-as-a-service businesses.

Competition is heating up fast

Muse competes with Instinct, which is raising funds at a ten billion dollar valuation, and other AI agents like Poke that exited to Cognition in July.

Speed is the competitive advantage

Both Muse and Instinct are shipping features rapidly. This week alone, both rolled out voice calling to stay ahead in the race for consumer adoption.
