Built with AI?

AI Website Detector

No AI builder traces found.

We look for what AI site builders such as Lovable, Bolt and v0 leave in a page. Code written with an AI assistant such as Cursor, Claude Code or ChatGPT leaves nothing to find, so we can’t tell whether AI helped.

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 2,275 sites whose makers we know, and publish what we get wrong.

    Answer requests for Markdown with a Markdown version of the page.

    Details

    Why it matters: A Markdown copy gives AI tools the page’s words without the HTML around them.

    Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)
    When a request to https://cnpj.biz asks for Markdown (its Accept header includes text/markdown), answer with a Markdown version of the page’s main content and the header Content-Type: text/markdown. Requests for HTML keep getting HTML; add Vary: Accept so caches keep the two apart.

None of the 27 other AI crawlers we know is kept out.

What it tells AI crawlers

It gives no Content Signals and no “noai” tag.

Like 71% of the 447 popular sites whose robots.txt we’ve read since 29 Oct 2026, it keeps no AI training crawler out. Of the 569 popular sites we’ve checked since 29 Oct 2026, 9% have a page drawn by scripts, 2% send a Markdown copy, 9% have an llms.txt and 3% offer a file for AI agents. How many websites block AI crawlers?

We read the site once, as our named bot: its robots.txt, read as crawlers read it, its home page and the files AI tools ask sites for. What we couldn’t read says so. robots.txt asks and doesn’t enforce: a firewall can treat AI crawlers differently from us.
