How it works
How to Create an llms.txt File
We read your sitemap, your homepage and the descriptions of your first 50 pages.
Remove what you would not want quoted and fix any title or description. The file updates as you type.
Download llms.txt and put it where it opens at your-domain.com/llms.txt.
What it is
What an llms.txt file is
An llms.txt file is a markdown file that tells AI agents what a site contains and where its useful pages are. It sits at /llms.txt, it is written to be read by both people and machines, and it is a proposal rather than a ratified standard. No search engine or assistant is obliged to read one.
The problem it addresses is narrow and real. A web page wraps its content in navigation, markup and scripts, so an agent working inside a limited context window spends tokens stripping all of that away before it reaches anything worth having. An llms.txt file hands it a short curated map in plain markdown instead. The file itself stays small; the detail lives behind the links and is fetched only when something needs it.
Jeremy Howard published the proposal in September 2024 and revised it to v2 in August 2026. The generator above writes the v2 shape.
What goes in it
What goes in the file
The proposal names one required element and fixes the order of everything else.
- 1
An H1 with the name of the site
The only part the proposal requires. In the editor it is the Site name field.
- 2
A blockquote that sums the site up
What an agent needs in order to make sense of the rest of the file. The Summary field.
- 3
Any amount of plain markdown
More detail, as paragraphs or lists, with no headings in it. The Details field.
- 4
Sections, each a list of links
Every section is an H2 with a markdown list under it. A link may be followed by a colon and a note on what the page covers.
# Title > Optional description goes here Optional details go here ## Section name - [Link title](https://link_url): Optional link details ## Optional - [Link title](https://link_url)
The notes after each link are the part worth spending time on. They are what an agent reads to decide a page is relevant before it spends anything fetching it.
A section headed Optional is a convention for links that can be skipped when a shorter context is needed. Under v1 that heading told context-building tools what to leave out. v2 removed those tools from the proposal and the special meaning went with them, so the heading is now a hint to the reader and nothing more. The generator puts your XML sitemap there.
Where it goes
Where the file goes
The root, at yourdomain.com/llms.txt, is the normal answer. v2 also allows a file on any subpath, so /docs/llms.txt covers the pages under /docs/, and where more than one file applies the most specific one wins. That is what lets a project controlling only a path, a GitHub Pages site for instance, publish one at all.
v2 also answers the question v1 left open, which is how an agent finds the file without guessing. Two standard link relations do it: rel="describedby" points at the llms.txt covering a page, and rel="alternate" type="text/markdown" points at that page's markdown version. Either can be an HTML <link> element or an HTTP Link: response header. The header form also covers non-HTML files and can be set in your CDN without touching a single page.
<link rel="describedby" href="/llms.txt"> Link: </llms.txt>; rel="describedby"
The markdown versions are the other half of the v2 proposal: serve a clean markdown copy of a page at the same URL, either with .md appended or with the extension replaced. v1 specified only the first form. Publishing tools had already diverged, so v2 accepts both.
The honest version
What is actually known about whether it works
Most writing on llms.txt overreaches, so here is what can be checked and what cannot. Every source below was read on 1 October 2026.
What can be checked
- The AI labs publish llms.txt files for their own developer documentation: OpenAI, Anthropic and Google.
- Chrome ships an llms.txt audit in Lighthouse, under its agentic browsing checks. It flags a server error on the file and marks the audit Not Applicable when the file is absent, because providing one is optional. The same page calls the file an emerging convention.
- Google says its own AI features in Search need no such file: "You don't need to create new machine readable files, AI text files, or markup to appear in these features." That is from its guide to AI features and your website.
- Publishing tools write the file for you. The proposal lists Mintlify, GitBook, Yoast SEO, AIOSEO and Wix.
What nobody has confirmed
- No assistant vendor has published a commitment to read a third-party llms.txt when it writes an answer. The crawler pages of OpenAI, Anthropic and Perplexity name robots.txt as the control. Where they mention llms.txt at all, it is as an index of their own documentation.
- Publishing a file for your own docs is not the same as reading everybody else's. Treat any claim that a named assistant reads llms.txt as unconfirmed unless that vendor says so directly.
- The proposal's author writes that the files are used most for software documentation, where coding agents follow them. That is his account of two years of adoption, not a published measurement.
- Figures for adoption and citation uplift come from third-party samples, not from any platform. We do not repeat them.
The practical read is that llms.txt is cheap to publish and has a clear use for documentation and agents, and that its effect on whether an assistant names you in an answer is unproven. Our fuller assessment is in the guide to llms.txt and AI visibility.
