About CheckIfImageIsAI
This site exists to answer one question that comes up constantly: was this image made by AI, and how would you know?
What the site covers
Three routes, because there are three honest ways to answer it.
- Provenance. A watermark or signed credential embedded at creation. A positive is evidence; a negative only means no signal was found.
- Pattern detection. Software that scores the pixels and returns a probability. Useful for images with no embedded signal, and never proof.
- Your own eyes. Observable checks — hands, text, light, depth, noise, file metadata — that need no tool at all.
The four main pages take one of those routes each, and the AI image detector page explains which route fits which situation. There is no page here claiming one tool is the best, because we have not tested them side by side and will not pretend otherwise.
How the content is judged
Every page follows the same rules, and they are rules about evidence rather than style.
Facts need a source. Statements about how a tool works, what it accepts, or what a study found are tied to a named page or paper, listed at the bottom of that page. Where a vendor's claim is quoted, it is quoted as a claim.
Inference is labelled as inference. When a conclusion is ours rather than a published finding — for example, why one check should run before another — the page says so in the sentence, not in a footnote.
No invented testing. We have not run controlled comparisons of detectors, so no page reports scores, sample sizes, or "we tested N images". The one large human study referenced is cited to its authors.
Corrections change the page. When something on a page is wrong or out of date, the page itself is edited and its date in the sitemap moves. We do not leave a correction in a comment somewhere else.
Who maintains it
One person writes and maintains this site. There is no editorial team, no reviewers, and no agency behind it — which is also why the pages are long on method and short on volume.
If you find an error, a broken source, or a claim you think is overstated, the address is on the contact page. Corrections with a link to better evidence are the most useful thing you can send.
How the site is built
Static pages, generated from source files and served through Cloudflare. No login, no comments, no newsletter, and no trackers of our own. What that means for your data is set out in the privacy page.
