Open the Content Credentials checker →How to do the same job with isGenAI
- Get the original file, ideally the download from the generator or the sender, not a screenshot or a copy re-saved by a social app.
- Open the free AI image detector at isgenai.com/ai-image-detector and upload the file. No account is needed.
- Read each finding with the field it came from: a C2PA manifest, an IPTC digital source type, a saved prompt or generator metadata.
- If the report says no AI evidence was found, treat that as “no record in this copy”, then look for the original source or run a pixel-based classifier if you need a probability.
Questions
Is isGenAI the same company as isgen.ai?
No. isGenAI (isgenai.com) is not affiliated with isgen.ai. They are separate products run by separate companies, with different websites, accounts and methods. An account on one does not work on the other.
How do I make sure I am on isGenAI?
Check the address bar: isGenAI lives at isgenai.com. The product name is written isGenAI, as one word. Pages on other domains are not part of isGenAI.
Which one should I use to check an image?
It depends on the question. isGenAI shows the records saved in the file and names where each finding came from; when a copy has no records it says so instead of guessing. isgen.ai describes a pixel-based score that it gives for any image. Many people use a record check first and a score as a second opinion.
