Meta Launches Muse, a Personal AI Agent That Books, Buys and Negotiates for You

By NewSunSEO | September 16, 2026

Meta’s new personal AI agent, Muse, can read your email, book your travel, fill in forms, negotiate on your behalf, and complete purchases with your card, and it keeps each user’s data inside its own isolated virtual machine so agents cannot reach one another. Meta announced the product on Tuesday, with a rollout in the United States across iOS, Android and the web, and support for the company’s AI glasses to follow. Meta says there is no advertising inside the product and that conversations are kept away from its ad systems.

What can Muse actually do?

Meta frames Muse as the difference between a chatbot and something that acts. Muse keeps working after the app is closed, makes suggestions nobody asked for, remembers preferences across sessions, and turns a saved recipe reel into a shopping list. An agent that fills forms and completes purchases is one that can complete the wrong form or the wrong purchase at speed with a saved card, which is why the security design carries so much of the product.

The agent runs on a model Meta calls Muse Spark, described in the announcement as the company’s most capable model to date, built for real-world agentic work. Meta also expects wide reach for the format, predicting that billions of people will have a personal agent within five years. Muse is the first product built to make that claim testable.

How does Muse handle payments?

Purchases run through Stripe’s Link with purchase protections, and Meta has promised support for Shop Pay and 1Password. Meta says credentials are stored so that Muse cannot see passwords or card details, and every action the agent takes leaves an audit trail you can review.

What keeps your data separate and safe?

The security architecture is more detailed than a typical launch-day assurance. Each user gets an isolated virtual machine that holds both the agent and their data, so one person’s agent cannot reach another’s. A separate system called Sentinel sits between Muse and the internet. It distinguishes read access from write access using time-limited permissions, allows low-risk tasks to run, and stops to ask before anything consequential happens.

Later this year, Meta plans a confidential version in which the company itself cannot observe what happens inside the workspace. Until that ships, the advertising promise is a policy rather than a property of the system. Meta says users can opt out of having their interactions train its models, and can tell the agent to forget particular things. Those commitments are real, and they are also revocable, a distinction worth keeping in view given that Meta earns most of its revenue from knowing what people want.

Why does the safety scaffolding matter so much?

Consumer agents have had a difficult run in public. A Meta researcher’s own experiment with an agent ended with files deleted, and booking platforms including Resy have told customers not to point automated agents at them. Sentinel is the layer standing between a useful assistant and a very fast mistake, which is why Meta has built the permission checks and the audit trail directly into how the agent operates.

How much does Muse cost?

Muse offers a free tier plus subscriptions at $20 and $100 a month. Meta says most people should be able to do what they need within the free tier, which positions the $100 plan at a narrower group of heavier users. The value of each tier will depend on how reliably the agent performs the tasks people hand it.
