The same photo elsewhere
Drop the photo into Google Images or Bing. If it appears under another seller or a web shop, the photo does not belong to this listing anyway.

What the score can tell you.
The detector looks for patterns that are common in AI-generated or heavily edited images. It does not prove a seller did anything wrong — when in doubt, ask for extra photos or videos.
- High score = elevated risk of AI-synthetic content
- Low score = no strong AI signals (still no guarantee it is "real")
- Use the score to ask further questions, not as a final verdict
Why AI photos on 2dehands are a problem
What goes wrong, and why the eye misses it.
The same listings with the same AI images appear on 2dehands and Marktplaats at once, often with a different phone number and a slightly different price.
A generative model has no model of the world: it predicts what a photo of this kind of thing usually looks like. That makes AI images convincing at a distance and inconsistent in the detail — the opposite of a real photo, which is messy at a distance and holds up close. Anyone scrolling a list quickly sees the convincing version.
The checker inverts that order. Every one of the listing photos is scored separately for patterns associated with synthetic generation, so you know which photo is worth zooming into before you message a seller or place a bid.
Spotting it yourself: four things to check
Zoom all the way in and work through these four. Together they cost half a minute.
Text in the image
Packaging, manuals and warning stickers get letters in AI images that look like language but form no words.
Light and shadow
Two objects in one photo with shadows falling in opposite directions, or a shadow without an object.
Hands and proportions
If someone appears in the photo: count the fingers and check whether the item's size matches the hand holding it.
How to use the 2dehands AI Checker
- Paste the link or upload the photos. The page fetches the listing photos; uploading works too when the link is restricted.
- Read the score per photo. The average across a listing is not what matters; the photo that stands out is.
- Zoom into what the score points at. Seams, letters, reflections, edges.
- Ask one verification question. Arrange to collect the item and pay on the spot. Whoever posted an AI listing will not get to a meeting.
A score starts a conversation, it does not end one. The detector cannot see who made a file, with which tool, or whether the seller is acting in good faith.
When it goes wrong
2dehands: report the listing using the report button and alert your bank immediately if a payment request was already paid.
Keep the listing URL and screenshots before you report: listings with generated imagery often disappear within a day, evidence included.
Frequently asked questions
Is the 2dehands AI Checker free?
Yes. No account, no daily limit and no payment method. The check runs on the same detector as the rest of this site.
Does a high score prove the 2dehands photo is AI?
No. The result is a warning signal, not proof of origin. A high score means the photo carries patterns common in generated or heavily edited imagery. Use it to ask sharper questions.
What does a low score mean?
That no strong AI signals were found. It is not a guarantee the photo is real: a compressed, cropped or forwarded photo loses signal. When in doubt, the follow-up question to the seller still stands.
Are my photos stored?
No. Images are processed to compute the score and are not used for model training by default. The history under the checker lives in your own browser only.
How accurate is the detector on 2dehands imagery?
Measured recall and false-warning rate are published with sample size and interval on the accuracy page. The newest generation of imagery is the weakest spot and that figure is stated separately.
