7 Things to Do with Meta Muse

You already lose hours to Marketplace refreshes, unread Messenger threads, and birthday posts that show up a day late. Meta Muse is a personal AI agent I would put on those jobs. It lives inside Facebook, Instagram, WhatsApp, Messenger, and Marketplace, and it can keep working after you close the app.

It just launched. I have not been running this for months. These are the jobs I would actually give it.

What can you actually do with Meta Muse?

Give it work whose raw material already lives in Facebook or Instagram, and that has to keep happening while you are busy. Muse sits inside those apps, then runs on Muse Secure VM, a dedicated computer with its own browser. It does the work, and it checks with you before sending a message or making a purchase. Same split as chat-based vs agentic AI. Meta's own demo: it turns a saved Instagram recipe reel into a grocery list.

1. The Marketplace Deal Hound

Meta Muse can watch Facebook Marketplace and named Buy Nothing groups for one specific thing, like a mid-century walnut dresser under $200, inside a set radius. When a listing matches, it pings you with the link, the price, and how long it has been up.

Prompt to send Muse:

Watch Facebook Marketplace and local Buy Nothing groups around [Park Slope, 11215] for a [mid-century walnut dresser, under $200, no particle board].
Check throughout the day. When one matches, ping me with the link, price, neighborhood, and how long it has been listed.
Do not message the seller until I say yes.

2. The Birthday Concierge

Meta Muse can pull upcoming birthdays off Facebook, remind you a few days ahead, and draft a message in your usual voice. If you want a gift, it looks at what they have actually posted and comes back with two or three ideas tied to those posts.

Prompt to send Muse:

Look at my Facebook friends and list birthdays in the next 14 days.
Three days before each one, remind me and draft a short message in my usual voice.
If I reply "gift," suggest 3 ideas based on what they have posted or liked recently, with a one-line reason for each.
Do not send anything until I approve.

3. The Move Out Manager

Meta Muse can take photos of what you are selling, write Marketplace listings, and price each one against similar posts nearby. It posts after you approve, then keeps a running list of who asked about what.

Prompt to send Muse:

I am sending photos of things to sell. For each item, write a Facebook Marketplace listing and suggest a price based on similar local listings.
Post each listing after I approve the draft.
Keep a simple tracker: item, price, who messaged, last reply, pickup status.
Do not message buyers until I say yes.

4. The Messenger Triage

Meta Muse can send a morning digest of unread Messenger threads: who is waiting, what it is about, and a drafted reply for the easy ones. Same idea as a daily briefing, except the pile is Messenger.

Prompt to send Muse:

Every weekday at 8am, digest my unread Messenger threads.
For each: who, what they need, urgency, and a draft reply for the easy ones.
Do not send anything. Wait for my approval.
Flag anything waiting more than 24 hours.

Key insight: Give Muse the jobs whose raw material already lives in Facebook or Instagram, and that have to keep happening during the workday.

5. The Gift Detective

Meta Muse can scan someone's public likes and recent posts before you buy, then suggest gifts with a one-line reason tied to something they actually posted.

Prompt to send Muse:

I need a gift for [Name] for [housewarming], budget [$60].
Check their public Facebook and Instagram likes and recent posts for clues.
Suggest 5 gifts they would actually want, each with one sentence tied to something they posted.
Do not buy anything. I will pick.

6. The Rental Radar

Meta Muse can watch named Facebook housing groups for neighborhood, budget, and must-haves, then alert you when a post matches, ideally before it has 40 comments.

Prompt to send Muse:

Monitor these Facebook housing groups: [group names] for a [1-bed in Greenpoint or Williamsburg], max [$3,200], must have [laundry in building], no [broker fee].
Alert me as soon as a match posts, with the link, rent, and comment count.
Keep checking during the day so I see it before it hits 40 comments.
Do not message the poster until I approve.

7. The Group Chat Herder

Meta Muse can poll a Messenger group for dinner availability, pick a restaurant that fits what people have liked or mentioned, and hold a reservation. It asks before it books or pays.

Prompt to send Muse:

Poll this Messenger group [group name] for dinner on [Thursday 7:30pm].
Find a restaurant in [East Village] that fits what people in the chat have liked or mentioned, [$$], [outdoor seating if the weather is decent].
Hold a reservation for [6] and show me the plan before you book or pay.
Do not charge or send the booking until I say go.
