ImgAuth
Check whether a photo was AI-generated or tampered with, and see the evidence.
ImgAuth looks at two different problems under one roof: whether a document's been visually tampered with, and whether an image shows the fingerprints of AI generation. Either way, you get a confidence score rather than a flat yes or no, plus a heatmap showing exactly which regions of the image triggered the result. That heatmap matters more than it might sound like. A confidence score on its own is hard to act on, showing you where the evidence actually lives in the image makes it something you can actually evaluate yourself rather than just trusting a number.

- Visual tampering detection for documents
- AI-generation detection for images
- Confidence scores on every result
- Heatmap evidence showing which regions drove the score
- Covers both documents and general images
Pros & Cons
Pros
- Heatmap evidence gives you something to actually inspect, not just a trust-me score
- Handles both document fraud and AI-image detection in one tool
- Useful for anyone who needs to sanity-check incoming images before acting on them
Cons
- No detector catches every generator or every tampering method, false negatives are possible
- Confidence scores still require judgment to interpret, they're not a legal verdict
- No stated accuracy rate or benchmark published on the site
FAQs
What exactly does the heatmap show?
The specific regions of the image that drove the confidence score, so you can see where the evidence is rather than just getting a number.
Can it catch every AI-generated image?
No detection tool is guaranteed to catch every generator, especially newer ones, so treat the confidence score as a strong signal, not a certainty.
