What llms.txt is
llms.txt is a short Markdown file at the root of a site that tells AI assistants what the site is and which pages matter most: a "# Title", a "> summary", and "## sections" with links to key pages. It does not replace robots.txt or a sitemap and it does not block anything. The full AISeeWhy check also tells you whether your important pages are listed in it.
