I ran the same product photo through 6 AI listing tools. 5 invented details that weren't in the photo.

One photo of a used camera lens. Visible mount, visible focal length, some wear on the edge. Nothing else you could actually confirm from looking at it.

What came back:

• Three said the glass was "free of scratches and fungus." You can't see fungus from outside.
• Two added a filter thread size that isn't visible anywhere in the image.
• One called it "recently serviced."

The generic copy isn't the problem. The problem is a buyer opens a dispute because the item doesn't match, and the listing technically promised no fungus.

Two things I found while trying to fix this:

Telling the model to "be accurate" barely works. It still hedges its way into claims. Constraining it to only describe what's visually verifiable works better.

Deleting bad phrases after generation beats regenerating. Deletion is deterministic. Regeneration is a coin flip.

Anyone else been burned by a description that overpromised? Did the platform side with you or the buyer?
