Built with AI?

AI Website Detector

No AI builder traces found.

Coding tools such as Cursor leave no traces, so this doesn’t mean a person made it.

AI traces: None found

How we know

AI site builders leave traces in the sites they make. We look for the traces of 53 of them and show every match with the line it came from, so you can check it yourself.

We test this on 2,312 sites whose makers we know, and publish what we get wrong.

  • With sources. Every fact above says where it came from and when.
  • Without guessing. When we couldn’t check something, we say so.

What this scan can’t tell you
  • Whether the business is real, honest or delivers what it sells.
  • Whether a site was made with AI when no traces were left: coding assistants and hand edits leave none.
  • How many people visit: we show popularity bands from public lists, not visits.
  • Anything beyond the home page as it was at the time of the scan.
