How to Use Muse to Plan a Trip

Muse, Meta's personal AI agent, was demonstrated at launch doing exactly this: opening a browser, researching, filling out forms, and booking travel once you approve. It runs on a secure cloud VM with its own browser, so it can work through airline and hotel sites the way you would, and it keeps working after you close the app — coming back when it finds an option or needs your sign-off. Meta says Muse checks with the person before sensitive actions like making a purchase, so the final 'book it' stays with you. The product began rolling out in the US on September 8, 2026, which makes early results promising but genuinely unproven.

• Reuters reported that in Meta's own internal tests some agent tasks failed — a flight-monitoring test stopped refreshing — and Meta's Vishal Shah acknowledged Muse will sometimes 'fail to finish things.'
• Heavy booking flows on airline sites may not complete on the first try while the product is days old.
• Availability outside the US has not been announced.

1. 1

   Open Muse where you prefer

   Use the Muse app on iOS or Android, muse.ai in a browser, or WhatsApp. Complex bookings work best in the app, where you can connect the services it needs.

2. 2

   Give it the trip skeleton

   Destination, rough dates, who is going, and a budget. One clear paragraph beats a long chain of follow-up questions.

3. 3

   Connect what it needs

   Meta says you choose which apps Muse connects to and how much access it gets — opt in one service at a time, such as email or payments, before asking it to book.

4. 4

   Let it draft before it books

   Ask for a full plan with prices first. Review the draft, cut what you don't like, and only then let it move to reservations.

5. 5

   Approve the purchases

   Muse is designed to check with you before buying. Review each booking in the audit trail and confirm before any card is charged.

A couple in Denver planning a 7-day anniversary trip to Portugal in May, with a $4,500 all-in budget and a preference for small coastal towns over cities.

Plan a 7-day trip to Portugal in mid-May for two adults, flying from Denver. It's our 10th anniversary, so lean romantic and slow-paced: coastal towns, wine country, one or two great restaurants a day — not a packed city itinerary. Total budget is $4,500 including flights. Find round-trip economy flights with no red-eyes, and suggest two base towns to split the week between, with highly rated places to stay under $180 a night. Build a light day-by-day outline and flag anything that needs reserving ahead. Do not purchase or book anything until I approve — show me the options with total prices first, then wait for my go-ahead.

• Dates and flexibility

  Shifting by a day or two often changes fares and room rates; telling Muse how flexible you are widens the search.

• Origin airport

  Nearby alternates can be much cheaper — give Muse your home airport plus any others you'd consider.

• Budget range

  A firm ceiling keeps Muse from anchoring on options you'd never pick.

• Traveler details

  Names as they appear on ID, ages, and any seating or accessibility needs matter the moment bookings start.

• Non-negotiables

  Nonstop flights only, a specific hotel brand, a must-see event — hard constraints upfront save a round of wasted options.

For this task, it is smart to make Muse check with you before it takes certain actions. Decide your rules up front and include them in the prompt.

• Purchasing flights or hotel rooms — Meta says Muse checks with you before purchases; keep it that way so every dollar spent is one you signed off on.

• Entering passport or ID numbers — Some international bookings ask for document details. Share them only when you've verified the booking is real and correct.

• Saving payment credentials — Muse can pay through Link by Stripe, which generates a one-time-use card so your real card details stay hidden. Prefer that over storing raw card numbers.

• Subscribing you to travel alerts or emails — Ask Muse to collect deals for you, not to hand your address to every fare-watching service it passes.

• ✓Give Muse one big brief instead of drip-feeding details — it works asynchronously, so a complete instruction lets it run while you do something else.
• ✓Ask for the audit trail: Meta says Muse shows everything it has done and plans to do, which is the fastest way to spot a wrong assumption.
• ✓Use the memory: tell Muse dietary restrictions or aisle-seat preferences once, and it should carry them into later plans.
• ✓If a booking stalls, don't retry blindly — ask Muse which step failed. Launch-week reporting showed some tasks simply stop, and a narrower re-run often gets further.
• ✓Keep an exported copy of the final itinerary outside Muse too; it protects you if a reservation doesn't complete.
