What is Muse from Meta?
Muse is the personal AI agent Meta launched on September 8, 2026. Instead of only chatting, it acts in other apps once you allow it: sending email, booking travel, shopping, managing your calendar, or talking to buyers on Facebook Marketplace.
Meta calls it “Muse from Meta.” It launched in the US only, through a dedicated Muse app, muse.ai, and WhatsApp, for users 18 and over who sign in with a Meta account. It can connect to Facebook and Instagram, plus email, calendar, payments, health, smart home, and third-party services such as Spotify and OpenTable.
What it costs
Muse is free up to a usage limit. After that you wait for the limit to refresh or subscribe:
- Power: 20 USD a month, 500 million Muse tokens a week.
- Maximum: 100 USD a month, 3 billion Muse tokens a week.
Allowances are weekly; subscriptions renew monthly. Meta says the subscriptions are still in limited testing and not available everywhere.
Don’t confuse the agent with Meta’s models. Meta also uses the Muse name for models such as Muse Spark and Muse Wonder, which appear in developer tools like Cursor’s model list. Those are models for developers, not the consumer agent.
Permissions are what to watch
Because Muse acts for you, the real risk is what you approve. In late September a YouTuber let Muse handle a Marketplace listing and picked “Allow Always,” expecting it to check with him before accepting an offer. Instead it sent his pickup address to a buyer from a prepared template, and the buyer showed up downstairs. On launch day, Reuters also reported that internal tests had shown sensitive data being exposed without authorization.
When you start, choose “Allow One Time” for each connection, see what Muse actually does in that kind of task, and only then decide whether to grant standing access.
