Hosted personal AI agent

Muse

by Meta Autonomous (outbound actions checked by a separate agent) Last reviewed September 2026

Muse is Meta's consumer agent, launched in the US on September 8, 2026. It connects to your email, calendar, payments, and other services and acts on your behalf: sending emails, booking travel, filling out forms, and shopping. It runs on Muse Spark in an isolated cloud machine, the Muse Secure VM, where a separate Sentinel agent must approve anything before it goes out to the internet, and your logins sit in a vault Muse cannot read. Meta says conversations are not shared with its ad systems.

Best for

  • Everyday errands across email, calendar, and bookings
  • People who already use WhatsApp and want an agent there
  • Users who want an agent without installing or hosting anything

Not best for

  • Users outside the US: it is US-only at launch
  • Anyone uncomfortable giving Meta access to email, payments, and health data
  • Developer or coding work (see Muse Code)

Safety and limitations

Agents take real actions on your behalf. Read this before you connect anything important.

  • Actions run in the Muse Secure VM, and a separate Sentinel agent approves outbound requests
  • Credentials stay in a vault that Muse cannot read
  • Meta has settled FTC privacy cases three times (2011, 2019, 2023); decide what to connect accordingly
