Meta gave Muse a browser, a way to pay and a place inside WhatsApp
Meta launched Muse in the United States for adults on September 8. People can use a separate app, a website or WhatsApp to give it work. Meta says Muse can browse, fill forms, send email, book travel, negotiate and keep working after the app closes. It can also make purchases through Stripe's Link system, which creates a one-time card number. Meta says the agent stops for approval before it sends an email or makes a purchase. The agent and user data live inside a dedicated cloud computer that Meta calls Muse Secure VM.

Meta's safety case comes from the company, not an independent security review. Meta says a separate system called Sentinel controls every outside connection, and the main agent cannot override it. Meta has not published a full outside audit or a rate for successful bypasses. The company has also not shown how Muse handles conflicting instructions from websites and connected apps. Muse becomes more useful as people give it more private data. A security failure would then expose more of that data.
Independent testers need to measure whether websites can trick Muse into exposing data, sending messages or changing a purchase. Muse's action log should show what it did and why. Approval rejection rates and Meta's security incident reports would show how the controls work in practice. Adoption inside WhatsApp will show whether ordinary users embrace a general agent or it remains mostly a tool for early adopters.
