Is this photo AI-generated? How to actually check
The reliable signals are provenance, not "AI detectors." Real camera photos usually carry EXIF with device, lens, and exposure data, and most major AI generators embed Content Credentials that label the image as AI-generated. Check those first. Pixel-based detectors that claim a confidence score are unreliable and false-accuse real photos.
Why "AI detectors" mislead
Tools that judge a photo purely from its pixels and return "92 percent AI" are weaker than they look. They produce false positives on ordinary photos and false negatives on AI images that have been lightly edited or recompressed. Once a photo has passed through a social platform, the compression alone can swing these scores. Treat any single pixel-based score as one weak signal, never as a verdict.
The signal that actually helps: provenance
Provenance is the recorded history of how a file was made. It is far more dependable than guessing from pixels:
- Camera EXIF. A real photo usually carries EXIF written by hardware: make, model, lens, exposure, and often a capture time. AI images typically lack this camera-written detail.
- Content Credentials. Major generators, including OpenAI's tools, Adobe Firefly, and Google's image models, embed signed Content Credentials that explicitly mark the image as AI-generated. A valid credential is a strong, tamper-evident signal.
How to check
- Look for Content Credentials. Upload the image to a viewer like contentcredentials.org, or check it on ChronoVerify, which detects them. A credential that says "generated by AI" settles the question.
- Look at the EXIF. Rich camera metadata leans toward a real capture; a complete absence of it is consistent with an AI image, a screenshot, or a stripped file. Absence alone is not proof.
- Weigh it honestly. When neither signal is present, the truthful answer is "not enough data to tell," not "fake."
The honest limits
Metadata can be stripped, and an AI image saved as a screenshot loses its credentials, so no single check is decisive. The goal is not a yes-or-no oracle. It is to gather the verifiable signals, state what they show, and avoid false accusations. ChronoVerify is built on that principle: it reports provenance and flags possible editing for review, and it never treats a weak pixel signal as proof.

Are AI image detectors reliable?
Not on their own. Pixel-based detectors produce false positives on real photos and false negatives on edited AI images, especially after a photo has been recompressed by social platforms. Use them only as one weak signal.
How can I actually tell if a photo is AI-generated?
Look at provenance. Real camera photos usually carry EXIF with device, lens, and exposure data, while most AI generators embed Content Credentials that explicitly label the image as AI-generated. Check both.
Do AI images have metadata?
AI images typically lack the camera EXIF a real photo carries, and many include signed Content Credentials that mark them as AI-generated. Neither signal is guaranteed, since metadata can be stripped.
What does it mean if there are no signals either way?
It means the result is inconclusive, not that the image is fake or real. Stripped images carry little to no provenance, so the honest answer is often that there is not enough data to tell.
