Muse

Meta's personal AI agent that takes action across your apps rather than answering questions, rolling out in the US on iOS, Android, web, and WhatsApp.

Details

Takes action instead of answering: Meta's own examples are online shopping, buying movie tickets, booking appointments, filling out a school permission slip, sending email, booking travel, and scheduling
Runs on Muse Secure VM, a dedicated virtual machine holding both the agent and the user's data with its own browser, so it works across apps from inside a sandbox rather than through app-by-app integrations
Keeps working after the app is closed and returns for approval before sensitive actions
Makes unprompted suggestions drawn from saved content and things the user mentioned earlier, rather than waiting to be asked
Users name the agent, give it an avatar, and tune how it communicates
Powered by Muse Spark 1.3, which Meta released six days earlier on September 2, 2026
United States only, 18 and over, on iOS, Android, web at muse.ai, and WhatsApp, with AI glasses named as coming soon
Free for most usage with paid plans reported at $20 and $100 per month; Meta's own announcement states only that it is free for most of what people need, and does not name tiers or prices
