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

    If agents could use the site, publish what they need where they look.

    Why it matters: Agents act for people: they look for these files to know what a site lets them do. Worth it only if agents can use the site.

    Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)
    If AI agents could use https://www.celsius.com for its visitors (to search it, book, buy or sign in), publish what they need at the standard addresses, and only what the site really offers: an MCP server card at /.well-known/mcp/server-card.json if it runs an MCP server, an API catalog at /.well-known/api-catalog (RFC 9727) listing its public APIs, and OAuth protected resource metadata at /.well-known/oauth-protected-resource (RFC 9728) if agents sign in.

  • Markdown copy

    Now Not offered: it sends the page’s HTML.

    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://www.celsius.com 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.

What it lets AI do

Not scored

Keeping AI out is the site’s choice, so it never lowers the score.

  • AI trainingOpenAI, Anthropic, Google, Meta and 4 moreLet in
  • AI answers and searchOpenAI, Anthropic, Google, Perplexity and 3 moreLet in
Every AI crawler, and how we checked

AI companies

Its robots.txt names none of the 24 crawlers of the 10 AI companies we know, so it lets every one in.

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.

If this is your site

  • Decide what AI may do with the site, and say it in robots.txt. Write the lines

Like 68% of the 1,691 popular sites whose robots.txt we read in October 2026, it keeps no AI training crawler out. 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.
