Look inside the file
How was this image made?
The complete history check for any image, free and instant. isGenAI reads the camera fields, saved prompts and signed Content Credentials an original file still carries, then tells you exactly what each record proves and what it does not: a creation record explains the file’s history; authorship and the truth of the scene are separate questions, and we keep them separate.

Read camera and location fields
The EXIF viewer reads camera settings, capture-time fields and GPS records on your device, with nothing uploaded. Every field is shown as the file stores it; because metadata is editable, a saved date is treated as a recorded value, not an independently verified capture time.
Read a saved prompt or workflow
The saved prompt extractor recovers generation instructions straight from the file, and the ComfyUI viewer exports a saved editor workflow or API graph as JSON. Both read the records that survive in the copy you supply, which is why the original file always gives the richest result.
Inspect signed Content Credentials
The C2PA checker validates signed records, recorded actions and source claims in memory, with no storage. Signature validity and signer trust are reported as two separate facts, so a cryptographically valid record with an untrusted signer is never mistaken for a trusted one.
Compare the original and an export
The metadata comparison tool shows precisely which creation records changed between two copies. Keep both files and the source link: a different hash pinpoints changed metadata or encoding even when the pictures look identical.

What if there are no Content Credentials?
Then you know something precise: this copy carries no readable signed record. The original never had one, an export removed it, or the record uses an unsupported format, and isGenAI distinguishes a completed check that found nothing from a check that could not run. No result proves human authorship. Ask for the original and preserve the source context.
Do Content Credentials survive a social media upload?
Not on X, in our test. In our platform metadata survival study, X removed the C2PA manifest, the IPTC AI source type, the EXIF camera and GPS fields, the saved prompt and the ComfyUI workflow from every test file we uploaded on 19 October 2026. Check the original file whenever you can; the study lists which platforms are still to be tested.
Does a valid signature prove an image is real?
A valid signature proves the signed record is intact under the checks performed. It does not establish that every claim is true, that the depicted event happened or that you trust the signer. isGenAI shows a recorded AI-generation action as a claim within that record, with the issuer, validation state and trust status named beside it.
Try the evidence yourself
The signed and unsigned control files contain identical pixels with different provenance records, so you can watch the checker separate them. The Image Metadata Lab adds seven controlled cases with downloadable files, hashes and reproduction code. These examples demonstrate file behavior, not real-world detector accuracy, and we say so on every case.
