How to get AI to sell my stuff

What you’ll be able to do

Right, so the loft situation. You know the one, boxes you haven’t opened since the last house move, a wardrobe with clothes that don’t fit anyone in your family anymore, maybe a games console nobody’s touched since 2019. This guide gets you from a pile of photos to an actual listing, on eBay, Vinted or Facebook Marketplace, with a title people actually search for, a description that won’t get you a complaint, and a price based on what things really sold for, not what you wish they’d sell for. Plus the scam stuff, because there’s always someone trying it on, and the tax bit, because HMRC now knows more than they used to.

None of this needs you to know anything about AI beforehand. Just a phone, some daylight, and the thing you’re trying to get rid of.

Before you start

Before any of this works, you need three things in your actual hands, not just in your head. The item itself, obviously. A label or serial number if there is one, because the AI is guessing from a picture and can get the model, size or year wrong. And a bit of patience for the first go, because the first draft is never quite right, it’s a starting point.

Photos matter more than which AI tool you pick. I mean, genuinely, more. A blurry photo taken at 11pm under a yellow bulb can sink a good description. Daylight, no flash, no filter, show the thing from a few angles including any damage. That’s it. That’s the whole photography lesson.

Then there’s the platform question, and this is worth thinking about before you start typing anything. eBay is free for UK-based private sellers, no final value fee when something sells, except for vehicles. You’d only pay for optional listing upgrades, a very large number of listings in a month, or posting overseas (eBay’s fees page has the detail). Vinted has no selling fees either, but the buyer pays a Buyer Protection fee on top of your price at checkout, so what they see is a bit more than what you asked (check vinted.co.uk/how_it_works for how it’s worked out). Facebook Marketplace is where people look locally, and it’s handy for anything too big to post. As a rough rule: Vinted is built around posting things with a prepaid label, eBay takes pretty much anything, Marketplace suits collection. You don’t have to pick one forever, just pick one for this item.

And the tax bit, so it doesn’t catch you off guard. Since January 2024, platforms report sellers to HMRC once you reach 30 or more sales, or receive about £1,700 (€2,000), in a calendar year, and they send you a copy of what they reported. It’s not a new tax, just visibility that wasn’t there before. Selling your own unwanted stuff is unlikely to be taxable at all, however many items you sell. A single item that sells for more than £6,000 might mean Capital Gains Tax, so check gov.uk if that’s you. But if you’re buying or making things specifically to sell at a profit, that’s trading, and over the £1,000 trading allowance in a tax year you need to tell HMRC. There’s a checker on gov.uk for working out which side of that line you’re on.

Get set up

You don’t need to download anything new for most of this. ChatGPT, Claude or Gemini, whichever you’ve already got or find easiest, all work fine for reading a photo and telling you what it might be, then helping write a title and description. Google Lens does a similar identifying job if you’d rather just point your phone camera at something.

eBay’s own app actually has some of this built in now: an AI option that writes a suggested description you can use as-is or edit, and a free AI background tool that removes or swaps the backdrop behind your item. Worth trying that first if you’re already on eBay, since it’s sitting right there in the listing flow. eBay says the app’s listing flow for private sellers in the UK starts with photos and a title, then AI suggests the details and category, and you review them before publishing. If you’re doing loads of items at once, Seller Hub on desktop has “Multiple listings from photos” which drafts several at a time. eBay is quite clear that you should check every autofilled detail before it goes live, and I’d agree, because autofill gets confident about things it doesn’t actually know.

Vinted’s own upload help doesn’t mention a built-in AI writer. So the way round that is: draft the description somewhere else, an AI chat, then paste it in. Same result, extra step.

Meta announced back in March 2026 that Meta AI on Facebook Marketplace can turn your photos into a draft listing with a price suggested from similar items listed nearby, and can auto-reply to “is this available?” messages. The announcement doesn’t say which countries get it. If you add photos to a Marketplace listing and don’t see it, it just hasn’t reached you yet, nothing wrong with your account. Meta’s separate Seller app is US-only for now, so don’t go hunting for it in the UK.

Try it yourself

Photograph the thing. A few angles, good light, any flaws clearly shown. Then open an AI chat and paste the photos in with this:

Here are photos of something I want to sell second-hand in the UK. Tell me what you think it is (brand, model, size, year if you can see it) and how sure you are. List what I should check on the item itself (a label, a serial number, a missing part) before I trust your guess.

It’ll come back with a guess and a confidence level, and usually a list of things to check. Go check them. Actually look at the label, the serial plate, whatever it points you toward, because the AI is pattern-matching on what your photo looks like, not reading minds.

Once you’ve confirmed what it actually is, give it the real facts and ask for the listing itself:

Write an eBay listing for this item. Facts: [brand, model, size, colour, what is included, every flaw]. Give me a short title that leads with brand, model and size, using the words a buyer would search. Then a short honest description: what it is, condition in plain words, every flaw, what is included. Do not add anything I have not told you.

Fill in the brackets properly. Don’t leave anything out, especially flaws, because that bit matters more than it sounds like it should.

Then price it. Go find sold listings, not active ones (more on that in a second), copy a handful of prices with condition notes, and ask:

Here are recent sold prices for items like mine, with condition: [paste]. Ignore outliers, give me a realistic Buy it now price and the lowest offer I should accept, and say in one line why.

Take that draft, whichever platform you’ve picked, and post it. Edit as you go, obviously, it’s a draft, not gospel.

Then postage, which is less of a faff than it used to be. On eBay, if you list with Simple Delivery, eBay picks the delivery service and recommends the parcel size and weight for you. On Vinted, you print the prepaid label once it sells and post it within 5 working days, using the shipping option the buyer chose. Weigh and measure the thing before you list it, not after, and bulky stuff you’d rather not box up is exactly what local collection on Marketplace is for.

Check the result

So before you hit publish, run through this properly.

Does the title carry the specifics, brand, model, size? Not “very nice dress”, but “New pink Zara mini evening dress”, that kind of thing, full of the words someone would actually type into a search bar. That example is Vinted’s own: brand, colour, type, unique features, and skip words like “nice” that don’t say how your item is different. Good advice wherever you’re selling.

Are every one of the flaws written down and also visible in a photo? Missing button, small stain, scratch on the case, whatever it is. If it’s not obvious, take a close-up. This is the single biggest thing that stops a “not as described” complaint later.

Is your price actually inside the range of what sold, not what’s currently listed? Big difference. An asking price is only what someone hopes to get, so if you price against active listings you can end up too high and wonder why nothing’s happening. On eBay, use Advanced search with your keywords and tick Completed listings, or use Product Research under the Research tab in Seller Hub, that one’s free. It’ll show you what actually changed hands.

Does your first photo show the whole item, in focus, nothing else in shot? Vinted’s rules are specific here: first photo whole item, no collages, no stock photos, no watermarks, daylight, no flash, every flaw shown somewhere in the set. Good rule for any platform really.

And, last check, is there anything in the background you don’t want strangers seeing? House number, post with your address on it, a family photo on the wall behind, your face in a mirror. Crop it or retake it.

If it doesn’t work

No views at all after a day or two: reword the title using words a buyer would search, not words you’d use to describe it to a friend. Recheck you’re in the right category. Try a better first photo. Small changes, but they matter.

Views but no offers: your price is probably wrong. Go back and check against sold prices again, not active ones, I know I’ve said this twice now but it’s the easy one to get wrong.

AI named the wrong model or size: happens, it’s guessing from a photo. Go photograph the label or serial plate directly and ask again with that in front of it. Usually far more reliable than a general product shot.

Someone claims “not as described” after a sale: reread your own listing first. If you genuinely missed something, the fair thing is to sort it, refund or partial refund, whatever’s reasonable. Under UK law, when you sell as a private individual your goods need to be “as described”. They don’t have to meet the “satisfactory quality” bar a business seller would, and used things get judged as used, but you still can’t misdescribe them. Vinted buyers can also claim if an item turns up “significantly not as described”.

On privacy: crop out anything personal before a photo goes anywhere, the AI chat included, and never paste a receipt, an address or card details into the chat just to help it identify something. On messages: never hand over bank details, your email, or a verification code to a buyer, whatever excuse they give. Keep everything on the platform, in the app’s own chat, not text or WhatsApp. If someone’s pushing hard to move the conversation off-platform, that’s the scam pattern right there, and you can check it directly:

A buyer sent me this: [paste]. Is this one of the usual marketplace scams (payment screenshots, overpayment, moving off the app, verification codes)? Tell me what to reply, staying on the platform.

Facebook itself lists these as the common patterns: moving to WhatsApp or text, payment screenshots you’re meant to just trust, “I overpaid, refund the difference”, fake emails that look like they’re from a payment app telling you to upgrade your account or pay a fee before you can accept the money, requests for verification codes. Check your own account for the money landing, not a screenshot someone’s sent you.

eBay’s real messages appear in Messages in My eBay, so anything claiming to be eBay that arrives by email with a link, forward it to spoof@ebay.co.uk and don’t click anything. Offering to finish a sale outside eBay is against its rules and loses you eBay’s protection. Vinted’s genuine emails come from an address ending @vinted.co.uk; a fake email asking you to open a link to confirm a sale is phishing, so forward it to phishing@vinted.com. And on Vinted, stick to the Buy now button, because a payment outside Vinted isn’t covered.

Questions people ask

Which AI should I use to write a second-hand listing?

ChatGPT, Claude or Gemini all work fine for reading a photo and helping write a title and description, so use whichever you already have. Google Lens does a similar identifying job if you'd rather point your phone camera at something.

Does eBay have its own AI for writing listings?

Yes. eBay's app has an AI option that writes a suggested description you can use as-is or edit, plus a free AI background tool. For lots of items, Seller Hub on desktop has "Multiple listings from photos". Check every autofilled detail before it goes live.

Does it cost anything to sell on eBay or Vinted in the UK?

eBay is free for UK-based private sellers with no final value fee when something sells, except for vehicles; you'd only pay for optional upgrades, very high listing volumes or overseas posting. Vinted has no selling fees, but the buyer pays a Buyer Protection fee on top of your price.

How do I price my item so it actually sells?

Price against sold listings, not active ones, because an asking price is only what someone hopes to get. On eBay use Advanced search with Completed listings ticked, or the free Product Research under the Research tab in Seller Hub.

What should I never send a buyer or paste into an AI chat?

Never hand over bank details, your email or a verification code to a buyer, whatever the excuse, and keep everything in the platform's own chat. Never paste a receipt, an address or card details into an AI chat, and crop anything personal out of photos first.

Keep exploring

If you liked this, there’s more in the same vein: “How to get AI to tell me what is in a photo” goes deeper on the identifying side. “How to get AI to compare products before I buy” is useful if you’re the one buying, not selling, for once. And “How to get AI to edit a photo” covers tidying up a photo, backgrounds and all. Tidy the background by all means, but never edit the item itself: a scratch you’ve painted out is a “not as described” claim waiting to happen.
