llms.txt is a proposed standard — a single Markdown file that tells AI assistants what your site is and which pages matter. Fill in the form below, then drop the file at /llms.txt.
# Your Company > One-sentence description of what you do and for whom. ## Key pages
Serve it at yourdomain.com/llms.txt with content-type text/plain. Want to know if AI engines actually read it? That's what MentionFlow is for.
What is llms.txt?
llms.txt is a proposed web standard, published in September 2024 by Jeremy Howard of Answer.AI. It’s a single Markdown file served at the root of your domain — yoursite.com/llms.txt — that gives large language models a clean, curated map of your site. Think of it as a sibling to robots.txt and sitemap.xml: where those speak to crawlers in their own formats, llms.txt speaks to AI assistants in the plain Markdown they read best — no navigation, scripts or markup to wade through.
What goes in the file
The spec is intentionally minimal. An llms.txt file begins with an H1 containing your site or project name, followed by an optional blockquote summary of what you do, and then Markdown sections of linked resources — your key docs, guides, and reference pages, each a bulleted link with a short description. An optional section titled Optional holds secondary links an assistant can skip to save context. Some sites also publish an llms-full.txt with the full page content inline. The generator above produces a spec-compliant file for you.
Is llms.txt worth adding?
Adoption has grown quickly among documentation and developer-tool sites since the proposal landed, and public directories now list thousands of sites that publish one. We’ll be honest, though — the same honesty we hold ourselves to elsewhere: major AI providers have not publicly committed to consuming llms.txt, so it is best treated as low-cost, forward-looking hygiene rather than a guaranteed ranking signal. It can only make your site easier for an assistant to understand, and it takes minutes to add. What actually moves your answers is worth measuring directly — which is what AI brand monitoring and AI crawler analytics are for.
llms.txt FAQ
What is llms.txt?+
llms.txt is a proposed standard: a single Markdown file at the root of your domain (yoursite.com/llms.txt) that gives AI assistants a curated, easy-to-read map of your most important pages. It was proposed in September 2024 by Jeremy Howard of Answer.AI, and takes its inspiration from robots.txt and sitemap.xml — but instead of rules for crawlers, it offers a human- and LLM-friendly summary of what your site is and which pages matter.
What goes in an llms.txt file?+
The spec is deliberately simple. It starts with an H1 containing your site or project name, an optional blockquote with a short summary, and then Markdown sections of linked resources — usually your key docs, guides and reference pages. An optional 'Optional' section lists secondary links an assistant can skip when it needs to save context. Everything is plain Markdown, so it stays readable by both people and models.
Where do I put the llms.txt file?+
At the root of your domain, served at /llms.txt (for example, https://yoursite.com/llms.txt), exactly like robots.txt. Some sites also publish an llms-full.txt containing the full text of their key pages inline, for assistants that want the content without following links.
Does llms.txt actually help my AI visibility?+
Honestly: it's low-cost, forward-looking hygiene, not a guaranteed ranking signal. Adoption is growing quickly among documentation and developer-tool sites, and a curated file can only make it easier for an assistant to understand your site. But major AI providers have not publicly committed to consuming llms.txt, so treat it as one small, sensible step — and measure what actually moves your answers with AI brand monitoring.
