Muse by Meta

Muse is Meta's personal AI agent, launched on September 8, 2026. It doesn't just answer questions: it does the work. Give it a goal and it plans, opens its own browser, fills out forms, sends emails, books travel, shops and checks out on your behalf.

Muse runs on Muse Secure VM, a dedicated cloud computer for each user, and is powered by Meta's Muse Spark model. A separate system called Sentinel controls what it can access and asks for your approval before sensitive actions like sending email or completing a purchase. Tasks keep running in the background after you close the app.

Available to adults in the US and Canada on iOS, Android, the web at muse.ai and inside WhatsApp. Free tier with weekly usage limits (a payment card is required at signup); Power plan $20/month and Maximum plan $100/month.
