How to find a website's llms.txt file

The file lives at a predictable place, so finding one takes seconds. Here is the reliable way, plus what to do when a site has not published one.

The quickest way

llms.txt follows the same root convention as robots.txt and sitemap.xml. To see any site's file, add /llms.txt to the end of its domain: 

https://example.com/llms.txt

If the site publishes one, it loads as plain text in your browser. If you get a 404, the site has not published one at the root (see the fallbacks below).

Step by step

  1. Go to the domain root and append /llms.txt. Use the bare domain, not a deep page. For https://www.example.com/blog/post, check https://www.example.com/llms.txt.
  2. Check /llms-full.txt. Documentation sites often publish a companion file at https://example.com/llms-full.txt containing the full page content, not just the link map.
  3. Try a documentation subpath. Some large sites host the file under their docs, for example https://example.com/docs/llms.txt. The spec allows a subpath, though the root is the convention.
  4. View source if needed. The file is Markdown served as text. If your browser tries to render it oddly, use View Source or fetch it with curl -s https://example.com/llms.txt.

If there is no llms.txt

A 404 simply means the site has not adopted the convention. Your options:

  • Confirm you used the root domain and a trailing /llms.txt, with no typo.
  • Check the documentation subdomain or subpath if it is a docs-heavy site.
  • If it is your own site, you can create one in minutes: paste your URL into our generator to build a draft from your sitemap, or follow how to create an llms.txt file.

Browse public directories

To discover sites that already publish llms.txt, community directories keep running lists: directory.llmstxt.cloud and llmstxt.site. For annotated, hand-checked examples with notes on what makes each one good, see our real-world examples.

Validate what you find

Found a file and want to know if it is well-formed? Paste it into our validator to check it against the spec: required H1, summary blockquote, section structure, and link syntax. It flags errors and warnings line by line.

FAQ

Where is the llms.txt file located? At the root of the domain, served as plain text, typically https://yourdomain.com/llms.txt.

What is llms-full.txt? A companion file with the full content of the listed pages, concatenated into one Markdown file for ingestion. See what is llms-full.txt.

Does every site have one? No. Adoption is growing but still optional; a 404 just means the site has not published one.
