Knocklog

llms.txt validator

Check the llms.txt on your site, or paste one you are writing. Knocklog reads it against the llms.txt format and tells you what agents will understand, what they will skip and how to fix it.

Or paste an llms.txt

What a good llms.txt looks like

llms.txt is a markdown file at the root of your site (/llms.txt) that gives AI agents a short map of the pages that matter. It starts with an H1 with your name, a one-line summary as a blockquote, then H2 sections (## Products, ## Docs, ## Pricing) with links, each followed by a colon and what the page answers.

Agents read it quickly and follow the links they need. Relative links, links outside any section and pages without a description are the most common reasons a file is skipped or misread.

Does llms.txt make a difference?

It does not replace good pages, and no operator promises to rank a site because of it. It helps agents that do read it find your best pages faster, and it costs little to keep. Knocklog shows whether agents actually fetch your llms.txt and which pages they read next.

Questions

Where do I put llms.txt?
At the root of your site, so it answers at https://yoursite.com/llms.txt, served as plain text or markdown.
What is the difference between llms.txt and llms-full.txt?
llms.txt is the short map with links. llms-full.txt, when you publish one, holds the full text of those pages in one file.
Is llms.txt the same as robots.txt?
No. robots.txt says what agents may fetch; llms.txt says what is worth reading. Test robots.txt with our robots.txt tester.
Can Knocklog write my llms.txt?
Yes. On Pro, Knocklog prepares a ready-made llms.txt and robots.txt from your site and the pages agents actually read.
