About

AI website builders and AI coding agents went from novelty to mainstream in a couple of years, and it became genuinely hard to tell, just by looking at a site, whether it was hand-built, generated end-to-end by a platform, or something in between. AI Website Detector exists to answer that one question as honestly as we can: paste a URL, and we'll show you exactly what evidence we found — and what we didn't — instead of handing back an opaque score and asking you to trust it.

That transparency is the whole design philosophy. Every signal that fires shows its exact matched evidence, every category we checked but found nothing for is listed too, and when we get a signal wrong — including on our own site — we write up what happened and fix it. You can read about a real false positive we found and corrected on our blog, and the full reasoning behind how every signal is weighted on the methodology page.

The tool is free, has no signup, and doesn't store the URLs you check. It's actively maintained — new builders and coding tools get added to the catalog as they show up, and detection rules get tightened whenever we find a false positive or a missed case.
