Add your site name and a one-line summary describing what your site does. Add an optional longer description for extra context.
2
Add your key pages

3
Copy or download
Preview updates live as you type. Copy the result or download the llms.txt file. Everything runs in your browser — nothing is uploaded.

❓ Frequently Asked Questions

What is an llms.txt file?+
llms.txt is a plain-text file placed at your site root (yoursite.com/llms.txt) that lists your key pages in a simple Markdown format so AI assistants and browsing agents can quickly understand and cite your site. It was proposed by Jeremy Howard in 2024 and is inspired by robots.txt and sitemap.xml.
Where do I put the llms.txt file?+
Upload it to the root of your domain so it is reachable at https://yoursite.com/llms.txt — the same location as robots.txt. On most frameworks you drop it in your public or static folder.
Does llms.txt help SEO or Google rankings?+
No. Google has confirmed llms.txt is not used for Search or AI Overviews rankings. Its purpose is agentic readiness — helping AI assistants and browsing agents read and cite your content accurately. Treat it as documentation for AI, not an SEO ranking signal.
What format should an llms.txt file use?+
An H1 title, an optional one-line summary in a blockquote, an optional description paragraph, then H2 sections that each contain a Markdown list of links in the form - [Page name](url): short note. This tool generates that exact format automatically.
Do AI assistants actually read llms.txt?+
Adoption is early but growing. Some AI tools and crawlers look for llms.txt today and others do not yet. Because it is a tiny static file with no downside, many sites add it now to be ready as adoption increases.
Is this llms.txt generator free?+
Yes, completely free with no login. Everything runs in your browser, so your site details are never uploaded to a server.
