Meta launches Muse, its personal AI agent, free to $100 a month by usage

Meta released Muse, a personal AI agent, to US users on September 8, 2026. It runs on Meta's Muse Spark family of models and was built internally under the code name Hatch, per CNBC and Meta's own announcement.

Muse is an agent, not a chatbot. Meta says it can book appointments, fill out electronic forms, and monitor home security camera feeds, carrying out the task rather than telling you how to do it.

The tiers are a usage meter, not a feature ladder

Here is the part the launch coverage mostly buried. Muse is free for most everyday use, then $20 a month or $100 a month. What separates the tiers is usage, not a locked-away feature set. An agent that opens a browser, works through a form and completes a checkout does more work than a single question, so the people who lean on it hardest are the ones Meta is pricing at the top. Read the plan as a meter on how much you hand off, not a menu of what Muse is allowed to do.

The safety pitch is one isolated environment

Meta's case for letting an agent touch your accounts rests on isolation. Meta says Muse runs in an isolated, secure environment, has no visibility into your passwords or payment methods, and checks with you before sensitive actions such as sending an email or making a purchase. That last gate is the one that matters in daily use: an agent that can finish a checkout is only as safe as the prompt that stops it before the charge.

Who can use it, and what it is not

At launch Muse is limited to US consumers aged 18 and over, on iOS, Android and a standalone site, with more countries promised over time. Keep one product separate from this one: Muse Code is Meta's developer command-line tool, aimed at engineers, not the consumer agent covered here.

If you are in the US, Muse is free to try before it costs anything. The two things to watch before you give it a card are whether the by-usage meter stays cheap once you push real workloads through it, and whether the confirmation prompt fires on every purchase, not just the first.
