Meta Muse went live on Tuesday as a personal agent that sends emails, books travel and completes a purchase on your behalf. It starts free with usage caps, then runs at 20 or 100 dollars a month. Meta says the agent lives on a dedicated, isolated machine, a claim landing less than two weeks after an 18 billion dollar settlement over harms to minors.
Key Takeaways
- Meta Muse plugs into email, calendars, payments, health apps, smart home and booking services
- Three tiers: free with caps, Power at 20 dollars a month, Maximum at 100 dollars a month
- US only at launch, on the web, iOS, Android and WhatsApp

ChatGPTAn agent wired into email, payments and health data
Meta shipped on Tuesday an assistant that no longer answers, it acts. Sending mail, booking a trip, filling forms, lowering a bill, turning a recipe into a grocery list, issuing invitations, completing a purchase through Stripe’s Link. The product ran under the internal name Hatch and now ships as Meta Muse.
Pricing is the first signal worth reading. A free tier with caps, a Power tier at 20 dollars a month, a Maximum tier at 100. That undercuts the 200 dollar monthly tier Meta was lining up for this same agent over the summer by a wide margin, before the product even reached users.
The connector list says more than the product page. Mail, calendars, payment methods, health and fitness apps, smart home, dining, shopping, music and ticketing. Each connection is switched on separately by the user and can be revoked at any point.
Meta documented the model layer behind the agent in the Muse Spark 1.3 write-up published on its research blog, which places the launch squarely in the model family the company has pushed since summer.
That lineage explains the economics. Meta had already priced Muse Spark 1.1 below rival models, and that cost base is what makes a free tier viable on an agent that burns tokens across every chained task.
Muse ships on the web, on iOS, on Android and inside WhatsApp, with the company’s smart glasses named as the next surface. The rollout stays inside the United States, and nothing has been said about a European timeline, where data protection rules bite hardest on exactly this kind of personal data access.
An isolated machine carrying the security claim
Meta moved first on the obvious objection. The agent runs on what the company calls a dedicated, secure computer with its own browser, and a separate component named Sentinel holds permission authority over every connector action and every network egress.
The engineering detail goes further than the marketing line. The model never handles real authentication keys, which are swapped for surrogate tokens. It never reads the raw page code of the sites it browses, only a simplified representation. Site passwords sit in separate storage and get injected at form-fill time, out of the model’s view. Meta laid this out in its engineering note on agent security, which also describes prompt injection detection by separate models and mandatory human approval on sensitive actions.
The architecture echoes the path Meta took on open models when it shipped Muse Glimmer as an agent sized for a single graphics card. Isolation was already the core argument there, at the scale of a local machine rather than a data center.
The record behind the promise is the harder part. The launch lands less than two weeks after an 18 billion dollar settlement covering harms caused to minors by the company’s social platforms. Before that came a 2011 privacy consent decree with the US trade regulator, a 5 billion dollar penalty in 2019, plaintext password exposure the same year and Cambridge Analytica.

The pressure Meta Muse puts on rival assistants
Distribution is where this actually shifts. WhatsApp sits among the most installed apps on the planet, and Muse arrives inside it on day one. No competitor holds a channel of that size to drop an agent straight into a conversation people already use daily.
The free tier applies the second squeeze. Rival agents currently sit behind paid subscriptions running from 20 to 200 dollars a month depending on the vendor. A free agent, even a capped one, resets the reference price across the consumer market.
Meta still arrives late here, and its own chief executive said so. Zuckerberg had conceded that agents were progressing more slowly than planned inside the company, which makes the Meta Muse timeline worth watching over the coming weeks.
For connected service providers, restaurants, ticketing platforms, booking sites, the shift is sharper still. If the agent becomes the entry point for booking and buying, each service loses its own interface as a storefront. The metric to watch is not Meta Muse user counts, it is how many partners agree to open their connectors.
