Was the image generated by AI?
Upload the image or video and see the probability it was AI-generated — a statistical screening that errs in both directions, not a verdict. Also check whether it carries a certificate of authenticity: that part is cryptographically verifiable.
Two different questions, two different answers
"Does this look like AI?"
A statistical answer. Lens returns a probability and the threshold used — never an audited precision figure, because none exists. It's a screening to prioritize human review, not forensic evidence.
"Does this file have a seal, and does it match?"
A cryptographic answer. If the file carries a certificate of authenticity, Lens confirms whether it's intact and who signed it — and any change to the pixels after signing breaks validation in a detectable way. This part is verifiable.
Most files circulating out there don't carry a seal — and having no seal doesn't mean anything by itself, it just means nobody signed it. Want to understand the difference between "unsigned" and "tampered with"? See how to check if a file was altered.
Frequently asked questions
How can I tell if an image was generated by AI?
Upload the file to Verisignum Lens. It runs a statistical screening that returns a probability of AI generation, along with the threshold used — not a binary verdict. It's indicative, not proof: the classifier errs in both directions.
Is the result proof that the image is or isn't AI?
No. Synthetic-content screening is a statistical classifier, subject to false positives and false negatives, and does not constitute forensic evidence. What is cryptographically verifiable is a different thing: the certificate of authenticity, which proves who signed the file and whether it was altered afterward.
Does it work for video and audio?
Yes. AI-generation screening covers image, video, and audio (MP3, M4A, and WAV, up to 5 minutes per file). The certificate of authenticity is verified across the same formats.
Do I need to have signed the file beforehand to verify it?
No. Verification works on its own, even on third-party files that never went through Verisignum.

Pricing Structured for Any Scale
From the freelance photographer who needs to certify their work, to large corporations processing thousands of media files a month via API.
The unit is the credit: 1 credit = 1 image, 1 second of video, or 1 second of audio — one minute of video uses 60. Usage beyond the included credits is billed at the end of the month, without interrupting service.
