Create an llms.txt file for your site

Generate an llms.txt draft using the llmstxt.org proposal format.

Example: Acme Inc: A short company summary, three curated pages, and an optional llms-full.txt link are ready to edit.

Describe the site

Example: Acme Inc is a small software company with product documentation and support guides. Change the sample to fit your site.

llms.txt proposal, checked 28 September 2026

XML is parsed in this browser only. URL-list format accepts one URL per line or “Page title | URL | one-line description”. This tool never fetches a URL.

Three example URLs are ready to seed.

A section is an H2 in the generated Markdown. Give each link a useful title and one-line description.

Section one

llms.txt draft

Example is ready. Review every title, URL, and description.

How it works

The generator follows the llmstxt.org proposal: an H1, a short blockquote summary, optional notes, and H2 sections containing Markdown links with descriptions.

The site name, summary, section names, page titles, descriptions, sitemap entries, and optional full-file link are assembled in your browser. Pasted sitemap XML is parsed with DOMParser; URL-list lines can also seed links.

The proposal describes a format, not an adopted search standard. research/ai-search-visibility.md reports a 12-week study across 83 sites with seven OpenAI, nine Anthropic, zero Perplexity, 67 Googlebot, and 193 Meta crawler requests. Those counts show fetching only; they do not establish citation impact or what each fetched file was used for.

Limits

  • llms.txt is a proposal. This generator does not submit it, publish it, or confirm that an engine reads it.
  • Sitemap input is parsed in your browser and is not fetched or uploaded. Seeded page names and summaries need your review.
  • A generated file is a concise link index, not an llms-full.txt file or a guarantee of search visibility.

Common questions

What is llms.txt?
It is a proposal for a Markdown file that gives agents background information and links to useful pages on a site. It is not a web standard adopted by all search engines.
Do major answer engines read llms.txt?
Evidence is limited. One 12-week log study across 83 sites recorded few requests from OpenAI and Anthropic, none from Perplexity, and more from Googlebot and Meta’s crawler. Fetch counts do not show whether a file affected citations.
Does the sitemap text leave my browser?
No. This tool parses pasted XML or URLs in the browser. It does not fetch the sitemap or send its contents to a server.
Should I create llms-full.txt too?
The proposal does not require it. If you maintain one, link it only after publishing a reviewed, useful full-text file and keep it current.
