What is llms.txt?
llms.txt is a proposed standard for telling AI systems what your site is about: a short markdown file at your domain root with your name, a description and a curated list of key pages. AI assistants answer a growing share of the questions your customers used to type into Google; this file is the cheapest way to make sure those answers describe you accurately and link to the right pages.
robots.txt vs llms.txt
They are opposites. robots.txt is a fence: it tells crawlers what they may not fetch. llms.txt is a welcome mat: it tells AI models what to read first and how to understand it. Most sites should have both, and you can check what your fence currently says with our robots.txt tester, including whether you are blocking the AI crawlers entirely.
FAQ
What is llms.txt?
A proposed standard (llmstxt.org, September 2024) for a markdown file at /llms.txt that gives AI assistants a curated map of your site: what it is, and which pages matter most. Where robots.txt tells crawlers what to skip, llms.txt tells them what to read.
Do AI companies actually use llms.txt?
Adoption is voluntary and still uneven, so treat it as a low-cost bet rather than a guarantee. Support is growing across AI tools and thousands of sites already publish one. It takes minutes, can only help, and being early costs nothing.
Where do I put the llms.txt file?
At the root of your domain, so it is reachable at https://yoursite.com/llms.txt, exactly like robots.txt. Serve it as plain text or markdown. If your site has a static folder for files like robots.txt and favicon.ico, it goes there.
What should I include in llms.txt?
Your site name, a one-sentence description, and a short curated list of your most important pages with a note on each: docs, pricing, key guides. Less is more. The file is for orientation, not a full sitemap dump; AI models read it to understand what you are and where the substance lives.
