Muse is Meta’s personal AI agent, launched in September 2026 and powered by the Muse Spark model. It is not a chatbot that answers one prompt at a time: Muse is an always-on personal agent with its own name and personality that chats with you, remembers what matters, connects to the apps and accounts you approve, and keeps working on your goals in the background between conversations. It reached the top of the free app store charts when it launched in the US as a free-first consumer app.
Every Muse user shares a dedicated computer in the cloud with their agent. The Muse Secure VM is a persistent, isolated Linux machine with a full browser, storage and compute, which Muse uses to do real work: researching, shopping, managing projects and following through on multi-step tasks. You reach Muse the way you already message people, in the Muse app on mobile or Mac, on the web at muse.ai, or through WhatsApp, and it turns long-term goals into plans, scheduled tasks and finished work.
Muse is a free-first app: it launched free in the US, and the listing is Freemium, so you can start with your own agent at no cost and step up to paid capacity for heavier background work.
Muse is for busy people who want a proactive personal agent rather than another chat window: someone to hold goals over weeks, run errands across their apps, and check back only when a decision is needed.
