What llms.txt proposes
A markdown file at /llms.txt listing a site's most useful pages with short descriptions, so a language model with a limited context window reads the right material rather than crawling navigation, cookie banners and boilerplate. It is a proposed convention rather than a ratified standard, and adoption by AI vendors is partial.
It is not robots.txt
robots.txt restricts crawling. llms.txt does the opposite — it recommends. It carries no directives, blocks nothing, and confers no permission. A page listed in llms.txt but disallowed in robots.txt is still disallowed, and the two files answer different questions.
Format
An H1 with the site name, an optional blockquote summary, then H2 sections containing markdown link lists with a short description after each colon. An optional section is conventionally used for material a model may skip when short of context. Plain markdown, no front matter.
Curate rather than dump
The value is selection. A file listing every URL on the site reproduces the sitemap and defeats the purpose, since the point is to spend a limited context window on the pages that actually answer questions. Twenty well-chosen entries beat a thousand.
Worth doing despite uncertain adoption
The cost is one small file. The genuine work is upstream: an AI system can only cite content that exists, is crawlable and answers a question directly. A site whose pages are thin gains nothing from listing them, which makes llms.txt the last step in an AI-visibility effort rather than the first.

Frequently Asked Questions
What is llms.txt for?
Listing a site's most useful pages so a language model with limited context reads those rather than crawling navigation and boilerplate. It is a proposed convention, not a ratified standard.
Is llms.txt the same as robots.txt?
No, it is the opposite. robots.txt restricts crawling; llms.txt recommends pages. It blocks nothing and grants no permission, and robots.txt still overrides it.
Should I list every page?
No. The value is selection — a file listing everything reproduces the sitemap and wastes the limited context the file exists to conserve.
Is it worth adding if adoption is partial?
The cost is one small file, so generally yes. But it only helps if the listed pages are substantive, which makes it the last step in AI visibility rather than the first.
