Spot fake listing photos before you buy
Too-good prices, stock-looking photos and sellers who will not send more pictures. Witness checks listing photos for signs of AI generation, and the reverse search helper finds photos copied from other listings.

What Witness is not for
- A real photo does not make a listing honest. Scammers copy real photos.
- Pay with protected methods and meet in person where you can.
- Witness reports a likelihood with a confidence score. It does not prove anything on its own.

Frequently asked questions
How do I tell if a seller's photo is fake?
Scan it with Witness, run a reverse image search for copies, and ask the seller for a new photo with a specific detail, such as today's date on paper.
Can Witness check a screenshot of a payment?
It can scan a screenshot as an image. Always confirm a payment inside your own bank or app, not from a screenshot.
Is Witness free?
Yes. You can try a few scans without an account, and a free account includes a monthly allowance. Pro raises the limits. See the pricing page for current plans.
Is a Witness result proof?
No. Witness gives a likelihood and a confidence percentage, plus an explanation. Use it as a second pair of eyes, not as a final ruling.
