Real llms.txt Generator example: before vs. after

An AI assistant answering a question about a site, before and after llms.txt existed.

Before · No llms.txt
  • AI guesses relevant pages from a full crawl

Without guidance, an AI assistant has to infer which pages actually matter, and can miss key docs entirely.

After · llms.txt published
  • AI reads a direct, curated list of key pages

A clear, curated file points AI tools straight to the docs and guides that matter most.

Frequently Asked Questions

What is llms.txt?
llms.txt is a proposed, markdown-based file published at a site's root that gives AI assistants a curated summary of the site and links to its most important pages, similar in spirit to how robots.txt guides search crawlers.
Is llms.txt an official, guaranteed standard?
It's an emerging convention, not a formally standardized protocol like robots.txt. Support varies by AI tool and is still evolving, but adoption is growing and it costs nothing to publish.
Does llms.txt replace robots.txt or my sitemap?
No, it's complementary. robots.txt controls crawler access, your sitemap lists all indexable URLs, and llms.txt is a curated, human-readable summary specifically aimed at AI assistants trying to understand your site quickly.
Where do I publish the generated file?
At your domain's root, so it's reachable at https://yoursite.com/llms.txt, the same convention robots.txt and sitemap.xml follow.
What should I link to in the Docs section?
Your most important, canonical pages, documentation, key guides, pricing, or core product pages. Keep it curated and high-value rather than listing every page on your site.

Also control traditional crawler access with our Robots.txt Generator and test existing rules with our Robots.txt Tester. Need a page's content as clean Markdown for an AI prompt? Try our HTML to Markdown Converter.
