What changed
Meta released Muse on September 8, an AI agent that runs tasks for you instead of just answering questions. It launched first in the US with over 3 million downloads in three weeks. The agent connects to your email, calendar, payments, and other accounts, then handles multi-step jobs like booking restaurant reservations, scheduling appointments, or ordering supplies.
Meta offers a free tier plus two paid plans: $20 per month and $100 per month. The agent runs on its own virtual computer in Meta's cloud and keeps working after you close the app.
What you can do with it now
Give Muse a repeating task your team does every week: "Find and book meeting rooms for Monday planning sessions" or "Check these five suppliers for the best price on printing paper." The free tier handles basic scheduling and research. The $20 plan adds more automations.
One tester had it make a packing list, email a friend about trip plans, and compile restaurant recommendations into a Google Doc. Small teams are using it for invoice reminders, appointment confirmations, and supply reordering.
What to keep in your own hands
Don't connect accounts that hold customer data, payment details, or confidential files until you test it on low-stakes tasks first. Turn on activity logs if Meta offers them. Set a calendar reminder to review what Muse actually did every Friday for the first month. If you pay for the service, know how to export your data and cancel before you give it access to anything you can't afford to lose. The agent keeps learning from your conversations, so decide now which topics stay out of the chat.
Meta's business model is selling ads based on what it knows about you. That creates a choice: either this agent becomes very useful because it knows a lot about you, or you limit what you tell it and it stays less useful. That's not a warning, it's just the deal. Pick your side of that line before Monday.
