Meta Launches Muse for Mac: A Personal AI Agent That Works Across Your Files, Mail, Messages, Calendar and Notes
Meta released Muse for Mac, a free consumer AI agent that acts across local files, mail, messages, calendar and notes, currently US-only.
Meta launched Muse for Mac on September 17, 2026, announced by Mark Zuckerberg and Chief AI Officer Alexandr Wang, following Muse's September 8 debut on iOS, Android, web and WhatsApp. The free macOS app is a hosted consumer agent (US only) powered by Meta's Muse Spark model, with cloud execution on Muse Secure VM where a separate Sentinel agent gates all outbound internet access. Permissions are opt-in, Full Disk Access is optional, and destructive actions like deleting files or sending messages require user approval; usage is free up to 100M tokens per week. Meta plans a user-key-encrypted Muse Confidential VM later in 2026 and runs a public bug bounty for Muse.
- First Muse version that directly acts on the user's computer across native apps
- Powered by Muse Spark; cloud side runs in Muse Secure VM with Sentinel gating
- Sensitive actions (deletes, sends) require explicit user approval
- Free up to 100M tokens weekly; US-only, no self-hosted model
- Meta can access user data to operate the service today
