The product exists and the announcement is real. Meta's own newsroom post states that Muse is a secure, private personal AI agent that proactively helps with people's goals and suggests ideas, running on Muse Secure VM, a dedicated virtual machine that houses both the agent and a person's data, and that talking to it works just like messaging another person, in the Muse app or directly in WhatsApp . On availability, the same post states that Muse is rolling out in the US on iOS, Android, and muse.ai, and coming soon to AI glasses, free for most of what people need, with subscription plans for people who want to do more .

On connected services, TechCrunch reports that the agent works by connecting to the user's apps and services like email, calendars, payments, and other things the individual may regularly use, such as apps for health and fitness, the smart home, dining, shopping, music and events, and that the company says the agent can do things like sending emails, booking travel, lowering bills, filling out forms, creating plans, turning recipe reels into grocery lists, sending party invitations, and making purchases, leveraging Link by Stripe for checkout .

Reuters reports that Meta rolled out on Tuesday an AI assistant that can autonomously send emails, sell a car and book travel on a person's behalf, despite internal concerns that the technology mismanages its access to sensitive personal data; the Muse agent, known internally as Hatch, will be available only in the U.S. initially, via a dedicated Muse app or Meta's WhatsApp messaging service, and is designed to access a person's apps across categories like email, calendar, payments, health, shopping and the smart home . Axios adds that initially Muse is available in the U.S. and works on iOS, Android and the web, with support coming soon for Meta's AI glasses .

On the post's privacy assertions, CNBC reports that Wang said the app runs within "its own isolated environment" inside the company's computing infrastructure, and "never sees your actual passwords or payment details" . On advertising, reporting adds a qualifier the post omits: Meta said it will not share details from Muse conversations with its advertising systems, though shopping-related interactions could indirectly affect the ads users see , and users can opt out of having Muse interactions used for AI training .

On pricing, CNBC reports that Meta unveiled its Muse personal agent app that comes in a free tier or a monthly subscription costing $20 or $100 depending on usage .
