Meta’s Muse hits Mac, letting the AI take actions on your computer

Meta’s new AI assistant app, Muse, is now available on Mac.

On the Mac, Muse can interact with your files, messages, calendar, notes, and mail, all within their native applications.

The new app follows the launch of Muse on mobile and the web earlier this month, when it quickly rose to the top of the U.S. App Store charts.

Just like on other platforms, you can control what Muse has access to on your Mac on an opt-in basis. In addition, the app will always ask for your approval before it performs sensitive actions, Meta says.

The desktop app comes at a time of intensifying competition between consumer-facing AI agents, which many in the industry believe will be the future of computing. The movement is disrupting the app industry , software-as-a-service businesses , and perhaps, eventually, even hardware, like the iPhone .

In addition to Muse, all the major players offer consumer-facing agentic AI. And other AI agents have found traction by letting people use AI agents via text messages. One of the first breakout hits in this space, Poke, exited to Cognition in July. Meanwhile, the newest AI assistant frequently brought up in tech circles these days, Instinct, is said to be raising more funds at a $10 billion valuation .

For now, the question is who can capture the most consumer market share in this space, and quickly. That’s led Muse and Instinct to rush to launch new features at a rapid pace — both rolled out voice calling this week, for instance.

As Mark Zuckerberg noted on X when announcing the Mac app, “The team is shipping fast.”
