The profiles its home page links. We haven’t checked who runs them.

AI use

  • AI training: asks ICC-Crawler and meta-externalagent to stay away.
  • AI training: names ClaudeBot with rules for some pages.
  • AI assistants: may read it for the people who ask them.

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.

How we scanned it

Only from what anyone can see: the site’s public pages and public records.

  • Politely. Our scanner, CheckAnySiteBot, says who it is and follows the site’s robots.txt.
  • With sources. Every fact above says where it came from and when.
  • Without guessing. When we couldn’t check something, we say so.
This scan, in numbers

  • 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.
