From the video

Facebook dropped Muse. Set it up, then test all three reasons yourself.

Muse is Meta's new personal AI agent, free to start in the US on iPhone, Android and muse.ai. This guide gets you signed in, then puts each reason from the reel to work: memory that learns who you are, shopping and booking with an approve step, and haggling on Facebook Marketplace. You type the messages and Muse does the legwork.

Eight pages: every message to paste into Muse, the exact menu paths, and fixes for when a step stalls.

The download is free. What we sell is at the bottom of the page, with prices.

What you will have when you finish

Muse on your phone or browser, and one real try at each reason from the reel.

  • Muse signed in with your Meta account, with Facebook and Instagram connected through Accounts Center, or kept apart if you prefer
  • A Memory file that already knows your name, your city and what you shop for, and that you can read and edit
  • Link by Stripe ready to pay, with a one-time card number for each purchase
  • A first trip planned and brought to the approval, where you pick Allow once, Allow for this task or Deny
  • A Marketplace haggle underway with your item, your ceiling and your opening offer

Six steps

Steps two through five have a message to paste into Muse, and every step says what only you can do. Talking to Muse works like messaging a person. Meta's own words: "there's no learning curve."

An iPhone, an Android phone, or a browser at muse.ai. Muse is for adults 18 and older and is rolling out in the US. With Facebook and Instagram in the same Accounts Center as your Meta account, Muse connects them automatically.

  1. 01

    Get Muse. On iPhone, download Muse from Meta from the App Store. On Android, search Google Play for Muse and pick the one from Meta. On a computer, go to muse.ai. Sign in with your Meta account. No Meta account yet? Make one from your Facebook or Instagram login, or with an email or phone number.

    App Store: Muse from Meta Web: muse.ai

    Your part: sign in. If your Facebook and Instagram sit in the same Accounts Center, Muse connects them automatically, and that is where reason one starts. Want them kept apart? Sign up with an email that is not linked to either.

  2. 02

    Tell it who you are. Muse opens on the Chat tab. Type a message the way you would text a friend, and send several in a row if you like. It does not need you to wait. Anything you mention once, it can remember and act on later, so give it a head start.

    Chat tab

    Paste into Muse, then fill in the brackets

    Hi Muse. Here is who I am, so you can remember it:
    - My name is [name] and I live in [city].
    - For work I [what you do].
    - I usually shop for [things you buy often].
    - I like trips to [places or kinds of trips], flying out of [home airport].
    - On Facebook Marketplace I am hunting for [items].
    Remember all of this. Then tell me in three lines what you know about me so far.

    Your part: fill in the brackets. The more specific you are, the better its suggestions get. For a fresh side chat later, tap the menu icon top left, then the pencil and note icon.

  3. 03

    Check what it remembered. This is reason one from the reel. Muse writes what it learns about you into a file called Memory.md, and you can open it, read it and change it. Then try one of Meta's own examples: turn a recipe reel you saved on Instagram into a grocery list.

    Assistant icon > Identity > Memory

    Paste into Muse

    Look at the recipe reels I saved on Instagram. Pick one I could make for dinner this week and turn it into a grocery list, grouped by section of the store.

    Your part: open Memory and fix anything it got wrong. To drop a whole topic, tell Muse to forget it. Coming from another assistant? Settings > Data Controls > Import memory brings your old memory over.

  4. 04

    Set up paying and book a trip. This is reason two. Meta recommends Link by Stripe, which issues a one-time card number for each purchase, so your real card number stays private. Or Muse can log into a store where your card is already saved. Meta says Muse has no visibility into your passwords or payment methods, and it asks for your approval before any purchase goes through. Shopping works the same way, from a phone case to a flight.

    Allow once / Allow for this task / Allow for this site / Always allow / Deny

    Paste into Muse, then fill in the brackets

    Plan a round trip from [home airport] to [city], leaving [date] and coming back [date], for [number] people. Keep it under $[budget] total. Give me three options with airline, times, stops and total price. When I pick one, set up Link by Stripe for payment if it is not set up yet, and bring me the approval before you book.

    Your part: pick the option you want, follow Muse's prompt to connect Link when it gets to checkout, and answer the approval. Allow once covers this booking. Deny stops it.

  5. 05

    Haggle on Facebook Marketplace. This is reason three. Tell Muse the item, the most you will pay and where to open, and it works the deal. Meta built Muse to negotiate for you. Its own examples are selling a car for more and lowering a bill.

    Paste into Muse, then fill in the brackets

    Find a [item] on Facebook Marketplace within [number] miles of [city]. The most I will pay is $[ceiling]. Pick the three listings that look like the fairest deal and open each one at $[opening offer]. Negotiate toward my number, keep it friendly, and check with me before you agree to a price or a pickup time.

    Your part: set the three numbers: the item, your ceiling and your opener. Then pick the deal Muse brings back and arrange the pickup.

  6. 06

    Optional: set your default approvals. Settings > Permissions holds them, so you decide how often Muse asks before it acts. The Activity log shows what Muse did for you, and Upcoming lists the tasks it has scheduled.

    Settings > Permissions Assistant icon > Activity log

    Your part: set the defaults you want there.

Menu paths and labels checked against Meta's Muse announcement and help pages on 22 September 2026. Muse is new and rolling out in stages, so a label may move.
