Built with AI?
AI Website DetectorNo 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.

1 fix, up to +10 points
- +10points
Sitemap
Now 12 listed in robots.txt, but the first answers 301.
Publish an XML sitemap and list it in robots.txt.
Details
Why it matters: A sitemap lists every page, so crawlers find the ones no link leads to.

Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)Add an XML sitemap at https://www.ibjapan.com/sitemap.xml that lists the site’s public pages, in the sitemaps.org format, and add the line "Sitemap: https://www.ibjapan.com/sitemap.xml" to https://www.ibjapan.com/robots.txt. Generate it from the site’s routes, so new pages are added to it.
Optional: 4 fixes few sites have yetup to +18 points
- +10optional
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.ibjapan.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.
- +4optional
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.ibjapan.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.
- +2optional
Links for AI tools
Now None in the home page’s headers.
Point AI tools to the site’s files in the home page’s Link header.
Details
Why it matters: A Link header points AI tools to a site’s files from any page, without guessing addresses.
Prompt for your coding assistant (Claude Code, Cursor, your builder’s chat)Make the home page of https://www.ibjapan.com send a Link header (RFC 8288) that points AI tools to the site’s files, for example: Link: </sitemap.xml>; rel="sitemap", </llms.txt>; rel="describedby"; type="text/plain". List only files the site serves.
- +2optional
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.ibjapan.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.

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 74% of the 859 popular sites whose robots.txt we’ve read since 29 Oct 2026, it keeps no AI training crawler out. Of the 1,053 popular sites we’ve checked since 29 Oct 2026, 9% have a page drawn by scripts, 3% send a Markdown copy, 10% 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.
