llms.txt Checker and Generator

Check a site's /llms.txt against the llmstxt.org format, or build a valid one from a short form. Enter a domain and this page fetches its /llms.txt and checks the file against the format published at llmstxt.org, rule by rule. The generator below turns a few fields into a file that already follows those rules. Free, no sign up, and no language model is called at any point.

Try one:

Generate an llms.txt

Fill in the fields. The file is built in this page in the order the format requires, so what comes out passes the checks above. Put the result at /llms.txt on your site.

Sections

One H2 section per block. Each line under it becomes a link: Title | https://url | optional note.
