AI or Not review

AI or Not focuses on one question, whether an image came from a generator, and answers it with a score, a breakdown by generator and a separate deepfake signal. The vendor says detection works from pixel content rather than EXIF data or C2PA credentials, which matters when you only have a screenshot or a re-saved copy from social media. The Free plan covers 20 image checks a month plus text detection and an API key, which is enough for occasional checks on viral photos or artwork. Pro costs $5 a month and adds $10 in monthly credits, which AI or Not says covers 500 image checks, and those credits roll over and also open up video, voice and music detection. Developers get an API and an MCP server. The cons are the low free cap and a large step from Pro to the $100 Business plan, and the 98.9 percent accuracy figure on its page is a vendor claim we did not test. We compared documented features and published prices.
