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.

Changes, earlier scans and alerts

Since our previous scan: This is our first scan of the site.

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

926 checks on 10 Oct 2026, with version 0.5.0 of our checks and version 1.1 of the score.

How we work · What each version changed · About our scanner

More sites like this: software or app

Automated findings from the site’s public home page and public records, as of 10 Oct 2026. They describe what we found, not the people or business behind the site, and they may be incomplete or out of date. This is information, not advice. Terms · Report an error

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.
