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.

  • Structured data

    Now None found.

    Add schema.org structured data, as JSON-LD, to the home page’s HTML.

    Details

    Why it matters: Structured data tells AI tools and search engines what the site is: a company, a shop, a product.

    Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)
    Add schema.org structured data to the home page of https://www.cainz.com as JSON-LD, in a <script type="application/ld+json"> tag in its HTML: an Organization with its name, url, logo and sameAs links to its official profiles, and a WebSite with its name and url. Add the type that fits what the site offers too, such as Product, Article or LocalBusiness. Use only facts that are true of the site.

Optional: 4 fixes few sites have yetup to +18 points

  • Files for AI agents

    Now None of the 8 we look for.

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

    Details

    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.cainz.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.
    +10optional

  • llms.txt

    Now None found.

    Publish a short Markdown summary of the site at /llms.txt.

    Details

    Why it matters: A short summary for AI models, at an address they can find. A proposal: few AI companies say they read it yet.

    Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)
    Create https://www.cainz.com/llms.txt as llmstxt.org describes it: a Markdown file with an H1 naming the site, a one-paragraph summary in a blockquote, and short sections listing its most useful pages as links, each with a line on what it holds. Serve it as text/plain or text/markdown.
    +4optional

  • 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.cainz.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.

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 70% of the 408 popular sites whose robots.txt we’ve read since 29 Oct 2026, it keeps no AI training crawler out. Of the 517 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.
