are AI image detectors accurate
Are AI image detectors accurate?
They can be useful, but their reliability changes with the file, the image type, and the generator being tested.
Why results vary
Image generators change quickly. Detectors also behave differently on photographs, artwork, screenshots, crops, and files that have been compressed several times.
False positives and false negatives
A false positive calls a real image likely AI. A false negative misses an AI-generated image. A serious tool should explain those risks instead of hiding behind one headline number.
How to use the output
Use it to decide what to check next. If the decision carries real consequences, verify the source and get a qualified human review.
Questions
Can a detector prove an image is real?+
No. A likely-real result means the tested signals lean that way. It does not prove where the image came from or who made it.
