# llms.txt: which products publish one for AI agents 131 of 151 products we drove publish an llms.txt. What the file holds, which products have one, and how to write yours. Source: https://agentdrives.com/standards/llms-txt · Updated 2026-10-24 · as data: https://agentdrives.com/standards/llms-txt.json · licence CC BY 4.0 llms.txt is a Markdown file that tells an AI agent what a site has and where to read it. Agents use it to find the right doc page fast. ## The numbers From our drives of 151 products, 1–24 Oct 2026 (https://agentdrives.com/data/facts?via=md): - Publish an llms.txt: 131 of 151 (https://agentdrives.com/data/facts?via=md#surface.llms_txt) - Docs our agent read without a browser: 151 of 151 (https://agentdrives.com/data/facts?via=md#docs.own) ## What it is llms.txt is a proposal, now at v2 [1]. The file is Markdown: a title, a short summary, then lists of links to the pages that matter. The only required part is H1 with the project name [1]. Each linked page can have a Markdown copy at the same address with `.md` added, so an agent reads text instead of HTML. [1] ## How many products publish one 131 of 151 products we drove publish an llms.txt. Our agent read the docs of 151 of 151 without a browser. ## How to add it 1. **Put it where your docs live.** At the root, as `/llms.txt`, or at a path that covers the pages under it. [1] It is not a /.well-known/ file. [1] 2. **Start with the name and one line.** An H1 with the product's name, then a short summary of what it does and who it is for. 3. **Link the pages an agent needs first.** Getting started, authentication, creating an API key, the API reference and pricing. One line each on what the page answers. 4. **Serve Markdown copies of those pages.** Add `.md` to each page's address. [1] The proposal also suggests a link from each page to its Markdown copy: rel=alternate type=text/markdown; rel=describedby [1]. ## Check it yourself 1. **Fetch it from a server.** You want a 200 and Markdown, not your HTML home page. ``` curl -s https://example.com/llms.txt | head -20 ``` 2. **Follow three of its links.** Each should answer with the page's text, without a sign-in or a bot check. ## Products that publish an llms.txt -
