About muse ai
Muse is Meta's personal AI agent, introduced on September 8 2026 in a post on about.fb.com titled "Introducing Muse: The World's First Personal AI Agent Built for Everyone."
Meta describes Muse as an agent that takes tasks, not only answers questions. It runs on Muse Spark inside Muse Secure VM, a dedicated virtual machine with its own browser. A separate Sentinel process has to approve outbound internet actions. Meta said Muse can send email, fill forms, book travel, and keep working after the app is closed, and that it asks before a purchase. Checkout can use Link built by Stripe. The company said Muse is rolling out in the United States on iOS, Android, and muse.ai, and inside WhatsApp, with a free tier and paid plans for heavier use. People search muse ai to find that app, to compare it with ChatGPT, and to read the privacy claims around a Meta agent that can touch mail and payments.
