Muse

Meta’s personal agent — one person, many apps, brand new.

Overall

The case

Muse launched in the United States on September 8, 2026. It is Meta’s personal agent, not the Meta AI chat bubble. You message it in WhatsApp or the Muse app; it runs on a dedicated Secure VM with its own browser; it can mail, book, shop (Link by Stripe), and keep working after you close the phone. That is a real execution surface. It is also a one-person agent: 18+, U.S.-only at launch, no household graph, and Reuters reported internal tests that stalled or over-shared. Presence in WhatsApp is not the same as a family concierge.

Best for
U.S. adults who want an agent in WhatsApp that can operate apps
Not for
Families who need shared memory, kid-safe permissions, or a vendor that is not Meta
Pricing
Free with a cap; Power $20/mo; Maximum $100/mo

Where it wins

  • Lives in WhatsApp on day one, plus iOS, Android, and muse.ai
  • Long-running agent on a Secure VM, not a one-shot chat
  • Connectors for mail, calendar, shopping, and more — with approval gates
  • Free tier Meta says covers most people; paid Power and Maximum for heavy use

Where it lags

  • U.S. adults only at launch; App Store lists 18+
  • Single-user agent, not a family graph
  • Meta data story: opt-out of training, encrypted VM promised later, Reuters flagged mishandled access in tests
  • Nine days old on this edition — reliability is a claim, not a year of household use

Why Muse is not #1

Onyt weights follow-through and household coordination. Zazu is built for that job. Keep a general model for thinking; use a concierge for the rest of the day.
