What changed
Meta launched Muse on September 8, 2026. It books flights, sends emails, manages calendars, and shops online. The agent runs on its own secure computer in Meta's cloud. It has three tiers: free with 100 million tokens weekly, Power at $20 monthly with 500 million tokens, and Maximum at $100 monthly with 3 billion tokens. It reached 3.4 million downloads in three weeks and hit number one on both the App Store and Google Play Store. US-only, age 18 and up.
What you can do with it
Pick one Friday task you repeat every week. The follow-up email to three clients. The restaurant booking for next week. The packing list for the trip. Give Muse access to one account — email or calendar, not both yet — and hand it that task. Watch how it does it. The agent shows you the browser as it works, so you see every click. If it books the wrong date or misses a detail, you know before it sends. The free tier gives most small teams enough tokens for ten to twenty tasks weekly.
What to keep in your own hands
Don't connect your bank or payment accounts until you've run ten tasks and watched how it handles mistakes. Don't hand it your customer list or client emails yet. Give it one email account, not your main one. Check what it can access in settings every Monday. Meta says it doesn't share your Muse data with its ad system, but you can revoke access to any app in one click. If the agent books the wrong flight, you pay. If it sends the wrong email, your client sees it. Keep the final click yours for another month.
