FAQ

Frequently Asked Questions

Ordinary questions first. Technical language underneath.

Can MediaChecker tell if a photo is AI-generated?
It can report synthetic indicators remaining in the file, with a confidence and evidence-quality label. It does not promise 100% accuracy and it does not call a person a fake.
Can you tell if a video is a deepfake?
Professional video signals look for face-swap, temporal identity flicker, and synthetic texture. Many viral clips are too transcoded for a strong class. Uncertainty is a valid output.
Is an AI detector always accurate?
No. Detectors fail on new generators, heavy compression, and mixed media. That is why MediaChecker uses eight independent engines instead of one score.
Can an edited photo still be real?
Yes. A camera capture can be cropped, colour-graded, or object-removed and still depict a real scene. Manipulation and synthetic are separate axes.
Can metadata prove an image is authentic?
No. Metadata is provenance: who, when, which camera, whether a C2PA manifest is present. It is not authenticity. It can be stripped or forged.
What is a secondary capture?
A file that photographed or screenshot another display of the media: a screen, a print, or another photograph.
Can MediaChecker detect screenshots?
The system looks for signs that media was recaptured from a screen or a print. A patterned fence is not automatically a monitor.
What happens when an image is copied multiple times?
Each save spends originality. Social apps re-encode. The picture may still be of a real moment. The file is no longer first-generation.
Does MediaChecker store my images?
This demo analyzes in the browser and does not retain media on the server. Signed-in usage counts are stored as a number, not as the file.
What does Generation Originality mean?
How close this file is to a first-generation encode. A real photo can receive a low originality score if it is a fifth-generation export.
Can a real photo receive a low originality score?
Yes. That is the point of the axis. Originality is not a moral verdict.
Does MediaChecker work with Facebook images?
Yes, as in-feed social copies. A Facebook share URL is not the original. Use the extension to sample on-screen pixels, or upload a camera-roll original if you have one.
Can social media compression affect forensic analysis?
Yes. Platform transcode discards first-generation evidence. The report will label the object as a social copy and lower evidence quality.
