Meta’s Muse AI Assistant Expands to Mac With File and App Access
Muse’s Mac app can access files, messages, calendar, notes, and mail, with opt-in permissions and approval required for sensitive actions. Launched September 17, 2026, it follows mobile and web releases earlier this month.
Meta’s AI assistant app, Muse, is now available on Mac, where it can interact with files, messages, calendar, notes, and mail within their native applications. The Mac version launched on September 17, 2026, following Muse’s debut on mobile and the web earlier that month, when it quickly rose to the top of the U.S. App Store charts.
Users retain control over what Muse can access on an opt-in basis, and the app will ask for approval before performing sensitive actions, according to Meta. Mark Zuckerberg announced the Mac app on X, noting that “the team is shipping fast.”
The Mac launch comes as competition among consumer-facing AI agents intensifies. The source notes that many in the industry believe AI agents represent the future of computing, with potential implications for the app industry, software-as-a-service businesses, and eventually hardware. All major players now offer consumer-facing agentic AI, and some have gained traction by making agents accessible via text message.
Among competitors, Poke — described as one of the first breakout hits in the AI agent space — was acquired by Cognition in July 2026. Another AI assistant, Instinct, is said to be raising funds at a $10 billion valuation and is frequently discussed in tech circles. Both Muse and Instinct rolled out voice calling features the same week as the Mac launch.
The rapid pace of releases reflects what the source describes as a race to capture consumer market share in the AI agent space, with Muse and its competitors pushing to launch new features quickly.
