LLMS.TXT · THE IDEA
One file instead of crawling the whole site
llms.txt gives AI systems a short map of the project: what the company does and which pages to read first.
The file does not replace sitemap.xml, robots.txt, or a sound site structure. It sits alongside them.
BACKGROUND
What llms.txt is and how it works
A practical introduction to llms.txt, robots.txt, and file structure.

QUESTIONS ABOUT THE TOOL
FAQ
Where do I upload llms.txt+
In the root of the domain, at /llms.txt. On website builders without root access, serve it through a proxy or an edge worker.
Does every site need one+
No. It helps most on sites with documentation, services, or a large content section, where important pages are hard to find by crawling.
Can I list every page+
You can, but a long list dilutes the signal. Keep it to the pages you want cited.
Does the tool publish the file for me+
No. It builds and validates the file. Publishing happens on your side.
