How to check Catawiki photos for AI warning signals
AI-generated photos can make a lot look convincing even when important details are false or missing. Use visual checks and the free Catawiki AI Checker before making a decision.
Why review the photos?
Auction images can make a lot look materially different from the object that is actually offered.
Check reflections and details
Compare lighting, shadows, text, seams, labels and repeated shapes across every available photo.
Ask for more evidence
Request a new photo or video showing a specific detail when the listing and its images do not agree.
Use the Catawiki AI Checker
- Paste the Catawiki lot URL or upload its photos.
- The checker reviews each image for patterns associated with AI generation.
- Read the warning signal and context for every image separately.
A score is a warning signal, not proof of origin, authenticity, fraud or authorship.
Open the Catawiki AI CheckerQuestions and limitations
Does a high score prove the photo is fake?
No. Compression, editing and new generators can affect results. Confirm concerns with provenance, additional photos and human review.
Does a low score prove the lot is genuine?
No. “No strong AI signal found” is not proof that an image or lot is authentic.
What should I do when unsure?
Pause the transaction or conversation and ask for independent, current evidence.
