What llms.txt is and how to write a good one
What llms.txt is
llms.txt is a proposed standard: a Markdown file at the root of your site that gives AI tools a curated summary and a list of the pages worth reading. Web pages are full of navigation, scripts, and layout; llms.txt hands an AI tool the short version.
It's an open proposal, not an official rule from any AI company, and no major AI search engine has said it ranks or cites sites because of it. Treat it as cheap, low-risk housekeeping that helps tools and agents that do read it, not a ranking lever.
The format
The parts go in this order. Only the first is required.
- An H1 with your site or product name.
- A blockquote with a short summary.
- Optional paragraphs with more detail. No headings here.
- H2 sections, each a list of links written as [name](url): notes.
- An optional section titled Optional for secondary links tools can skip when they need a shorter context.
What makes a useful file
Write the summary the way you'd want an AI answer to describe you. Pick your best pages rather than every page: product, pricing, documentation, key guides, and policies. A short note on each link tells a tool when to read it.
Frequently asked
Questions, answered.
What people ask before they use the llms.txt generator.
A Markdown file at yoursite.com/llms.txt that summarizes your site and lists the pages AI tools should read. It follows an open proposal published at llmstxt.org.
There's no public evidence that it does, and no major AI search engine has said it uses the file for ranking or citations. It can help AI tools and agents that read it find your best pages quickly, and it takes minutes to publish.
robots.txt tells crawlers what they may access. llms.txt suggests what's worth reading and summarizes your site. They work together; llms.txt doesn't block or allow anything.
A common companion file that includes the full text of your key pages in one document. It isn't part of the core proposal. Start with llms.txt; add a full version only if your content suits it.
At the root of your site, for example https://example.com/llms.txt, served as plain text. A section of a site, such as /docs, can have its own file at /docs/llms.txt.
No. You choose the pages, and the file is written in your browser. We only fetch something when you ask the tool to check a site's existing llms.txt.
