Meta's Muse AI assistant arrives on Mac with file and app control

Meta's AI assistant Muse is now available on Mac, allowing it to interact with files, messages, calendar, notes, and mail within native apps. Users control access on an opt-in basis, and the app asks for approval before sensitive actions. The launch intensifies competition among consumer AI agents, with Muse and rivals like Instinct rolling out features rapidly.
The Mac release follows Muse's mobile and web debut earlier in September, which quickly climbed to the top of the U.S. App Store charts. The desktop version integrates with native macOS applications, handling files, messages, calendar, notes, and mail. Users grant access selectively, and the app requests confirmation before executing sensitive operations.
This launch intensifies the race among consumer AI agents. Competitors include Instinct, reportedly seeking a $10 billion valuation, and Poke, which was acquired by Cognition in July. Both Muse and Instinct introduced voice calling this week, highlighting rapid feature development. Meta's CEO noted the team's fast shipping pace, while the broader industry sees these agents potentially disrupting app stores, SaaS, and even hardware.
The arrival of desktop AI agents like Muse could reshape everyday computing for consumers, who may delegate routine tasks like email sorting or calendar management to an assistant. This may also pressure app developers and SaaS providers, as users could rely on a single agent rather than individual apps. Privacy implications are significant, though opt-in controls and approval prompts may mitigate some risks. Ultimately, the competitive rush could accelerate adoption, but also raise questions about data security and user autonomy.
