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.

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
