What llms.txt is, and what Studio does.

Transcript

When someone asks ChatGPT, Claude or Perplexity about a business, the assistant often goes and reads the website. But a web page is built for people — navigation, menus, scripts, ads. The useful part is buried, and the agent has to guess what matters.

llms.txt is a small text file at the root of your site. It's a proposal from llmstxt.org — a plain Markdown map: what your site is, and links to the pages that explain it best. Documentation, product, pricing, policies. Not every page — the ones that matter.

Let's be clear about what it doesn't do. It doesn't guarantee rankings, citations or traffic. Some AI systems read it, some don't. What it does is remove the guessing for any agent that chooses to look.

llms.txt Studio builds the file from what your site already publishes — your sitemap, your titles, your descriptions. No AI model invents a summary of your company. It's free, and you don't need an account.

Already have one? Validate it. You get two answers: is it a valid llms.txt under the current spec, and how useful is it — a grade from 0 to 100, with every deduction shown.

Then there's the part that matters after launch. Sites change. Pages move. Links break. And the file just sits there, quietly going stale. Monitor checks it every week. If the grade drops, a link dies, or the file drifts from your site, you get an email with the exact lines that changed — and one click to regenerate. It also shows you when a documented AI crawler fetched your file, with the timestamp.

Generate one now, free, at llmstxt.echorank360.com. Keep it correct with Monitor. That's the whole product: a correct, current file, and evidence when something touches it.

What this is

One small file. Three useful jobs.

  • Generate
    Turn your existing website into a clean, structured llms.txt. We use your sitemap and your own page content to identify and organize the pages that matter. Same website, same inputs, same output.
  • Validate
    Already have an llms.txt? Check it against 16 format, structure, link, content-type, and crawler-access rules. Every issue includes the rule that triggered it and where we found it.
  • Monitor
    Websites change. Your llms.txt should change with them. Monitoring checks that the file is still live, valid, and aligned with your site — and can show you when recognized crawler user-agents fetch your canary URL.
What this is not

Built from your website. Not invented by AI.

Your llms.txt should describe what is actually on your site. So we don't ask an AI model to rewrite your company, invent summaries, or decide what you meant.

We use:

  • your sitemap
  • your page titles
  • your meta descriptions
  • your headings
  • your live URLs

If important information is missing from your website, we don't make it up.

Your content stays your content.

What you get

See what a real llms.txt looks like.

We generated the file for EchoRank360 using the exact same system. It contains 60 links across Docs, Product, Blog, About, and Optional sections, received an A grade from the validator, and was published without hand-editing.

How grading works

Know if your llms.txt is actually healthy.

A file existing at /llms.txt doesn't mean it's useful. The validator checks 16 rules covering structure, formatting, accessibility, links, file size, and crawler-related information.

Two verdicts, not one blended number. Spec validity asks whether the file is a valid llms.txt at all: it exists, is served as text, has an H1, its file lists are well formed, and it is not an HTML page. Quality is Studio's set of recommendations, graded 0 to 100.

Start at 100. Problems subtract points according to published rules. A missing file or HTML page served in its place fails immediately. Informational findings — such as blocking an AI crawler in robots.txt — don't lower your score because that may be an intentional choice.

No mystery score. Every deduction is shown.

You'll know when:

  • your llms.txt disappears
  • your validation grade drops
  • a link breaks
  • the file drifts from your live website
  • monitored content changes
  • a recognized AI crawler user-agent fetches your canary URL

Maximum one alert per day.

See when recognized AI crawler user-agents fetch it.

Monitoring can add a small canary link to your llms.txt. If a crawler follows that URL, we record the timestamp and user-agent string.

We currently recognize user-agent strings associated with:

User-triggered fetch
  • ChatGPT-UserOpenAI
  • Claude-UserAnthropic
  • Perplexity-UserPerplexity
  • meta-externalfetcherMeta
  • Amzn-UserAmazon
  • MistralAI-UserMistral
  • DuckAssistBotDuckDuckGo
Search index
  • OAI-SearchBotOpenAI
  • Claude-SearchBotAnthropic
  • GooglebotGoogle

  • ApplebotApple
  • Amzn-SearchBotAmazon
Training
  • GPTBotOpenAI
  • ClaudeBotAnthropic
  • meta-externalagentMeta
  • AmazonbotAmazon
  • CCBotCommon Crawl

Every entry is cited to the vendor's own documentation on /help. Robots-only control tokens have no user-agent and never appear in a fetch log.

This gives you evidence that a user-agent identifying itself as one of these crawlers fetched the URL. It does not prove that the company behind that name operated the request, because user-agent strings can be spoofed. And if you see no fetch, that doesn't prove an AI system ignored your llms.txt.

We show the evidence. We don't exaggerate what it means.
