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

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

   Copy prompt

   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

   Copy prompt

   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

   Copy prompt

   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

   Copy prompt

   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.
