Free llms.txt generator.
Build a valid llmstxt.org-format file for your site in seconds. Everything runs in your browser. Nothing is sent to a server.

Optional: secondary links
Lower-priority pages that still help an LLM understand your site (legal, press, careers, etc.).
What is llms.txt and why does it matter?
llms.txt is a proposed standard that gives AI models and agents a quick summary of your website. Think of it as a cover letter for machines: a single file at your site root that tells an LLM what your site is, what its key pages are, and how they relate to each other.
The format was proposed by Jeremy Howard and documented at llmstxt.org. It uses simple Markdown: an H1 heading for your site name, a blockquote for a one-line description, optional body text, and H2 sections with categorized link lists.
Adoption by AI search engines is still early. Most crawlers pull from your HTML, schema markup, and sitemaps. But llms.txt costs nothing to ship and carries zero downside, so it belongs in any AI-readiness checklist alongside Markdown twins, clean structured data, and citable page content.

Frequently asked questions.
What is an llms.txt file?
llms.txt is a proposed convention for websites to provide a machine-readable summary of their content to large language models and AI agents. It lives at your site root (yoursite.com/llms.txt) and follows a simple Markdown-like format with your site name, a description, and organized links to key pages.
Does this generator send my data anywhere?
No. This tool runs entirely in your browser. Nothing is sent to any server. Your site information stays on your machine.
What format does llms.txt use?
llms.txt uses a Markdown-based format defined at llmstxt.org. It starts with an H1 heading (your site name), a blockquote summary, optional body text, then H2 sections containing link lists. Each link follows the pattern: - [Title](URL): Description.
Do AI search engines actually read llms.txt?
Adoption is still early. Most AI crawlers rely on HTML, schema markup, and sitemaps rather than llms.txt. Shipping one is a low-cost hedge: it takes minutes to create and carries zero downside, but it should not replace proven on-page optimization, structured data, and clean HTML.
Where do I put the llms.txt file on my site?
Place it at the root of your domain so it is accessible at yoursite.com/llms.txt. On most hosts this means dropping the file into your public or static directory alongside robots.txt and favicon.ico.
