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 ask the seller directly.

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

Signals, not proof.Avoid uploading sensitive photos or photos of children. If you seriously suspect something: report the lot on Catawiki.
