On Marketplace, it does some of the work. It writes listings from your photos and drafts replies to buyers. Keep it on Allow once and never give it your home address. Etsy and eBay are harder: Muse has no connector for either.
Our take: Muse helps with the slow parts of selling: listings from photos, and replies to the questions buyers ask over and over. We would not let it send replies on its own yet. One seller tapped Allow Always, and Muse sent his pickup address to a buyer. Keep Muse on Allow once and read each reply before it goes.
| Where you sell | What Muse does |
|---|---|
| Facebook Marketplace | Writes listings from photos. Some sellers say it posts them and replies to buyers. |
| Etsy | No Muse connector. Etsy's rules ban unapproved automated tools. |
| eBay | No Muse connector. eBay's rules ban bots and AI agents without its OK. |
| Shopify | A connector for your orders, stock and sales numbers. |
| Facebook Page, Instagram, Meta ads | Connects in a few clicks. Drafts posts and ads for your review. |
| Getting paid | Shop Pay and PayPal in Muse are for buying, not for getting paid. |
Checked against Meta's Muse and Marketplace help pages, muse.ai/business and the Etsy and eBay terms.
What does Muse do on Marketplace?
Send Muse a photo and it writes the listing. One seller says the listing went live a minute later. Another uses it to write ads and handle messages with buyers. Meta's AI chief says Muse's Facebook connector includes Marketplace, but Meta has no help page on selling with it.
Replies are hit or miss. Since late September, users say Muse asks before every message, and one says Marketplace sends fail with an error. Meta has not announced a change. Plan to approve each reply. One seller says Meta locked their account while Muse posted their listings. Meta has not said why.
Is this Meta AI's listing tool?
No. Facebook has its own seller tools that are not Muse. Meta AI in Marketplace drafts a listing from photos and can answer “Is this available?” for you. The separate Seller app does bulk listings. Muse is Meta's agent app. New to it? Read what Meta Muse is.
Buying, not selling? One reviewer had Muse find couches on Marketplace, though another tester found its Marketplace watch did not work. Try the Marketplace deal hunt job.
What went wrong for one seller?
Matt Robb, a YouTuber, asked Muse to handle his Marketplace replies. Muse offered two buttons, Allow One Time or Allow Always, and he tapped Always. Muse then sent the buyer his pickup address and told the buyer Robb was home when he wasn't. An offer also showed as accepted. Meta says that part was a display error it has fixed.
Meta reviewed it and said its privacy controls held. It promised a clearer permission prompt. Its help page still says Always allow lets Muse take that kind of action again without asking.
How do I stay safe?
- Tap Allow once (it may say Allow One Time), never Always allow, when Muse asks to send a message.
- Never give Muse your home address for buyers. Meta's own Marketplace advice says to keep it private.
- Meet in a public, well-lit place, or ship the item.
- Tell Muse to ignore payment screenshots and overpayment stories. Meta says never trust a screenshot of a payment.
- Have Muse say an AI wrote the message. The Muse terms bar hiding it where the law asks you to say so.
- Read every reply before it goes. The Muse terms make you responsible for every message and deal.
- If you only want drafts, don't turn on automatic sending.

Is there Muse for business?
Yes. Muse for Small Business adds skills and connectors to the same plans: free, Power at $20 a month and Maximum at $100. It works in the US and Canada, for people 18 and up. Shopify lets Muse read your orders, stock and sales. Your Facebook Page, Instagram stats and Meta ads connect in a few clicks. Meta also names QuickBooks, Stripe, Klaviyo, Canva, Slack and Notion.
Meta says nothing posts, sends or spends without your OK. Its own example: “Analyze my best-performing posts and ads. Then draft a week's worth of posts and plan an ad campaign using my existing content and industry trends for my review.”
Can Muse sell on Etsy?
Not through a connector. Muse has none for Etsy. Etsy's terms ban crawling and scraping, and its API rules ban unapproved automated tools. Etsy also says you are responsible for all activity on your account.
Muse can still help off the site. Ask it to rewrite your titles, tags and descriptions, then paste them in yourself. Some vendors advertise custom Etsy connectors for Muse. Meta doesn't review those, so grant access with care.
What about eBay and other sites?
One user says Muse listed books on eBay from photos. Another says it lowers eBay prices based on views. eBay's user agreement bans bots and AI agents unless eBay says yes first. It also bans sharing your login. If you try it, you risk your eBay account.
We found no Muse stories for Poshmark, Depop or Mercari.
