llms.txt
A plain-text file at your site root that tells AI models what your site is and where the important content lives — the AI-era robots.txt + sitemap.
llms.txt is a proposed standard: a single Markdown file served at /llms.txt that gives large language models a clean, curated map of your site. Where robots.txt controls access and sitemap.xml lists URLs, llms.txt adds meaning — what the site is, and which pages actually matter.
What it contains
- An H1 with your site or product name.
- A short blockquote summary of what you do.
- Curated sections of links to your best content — docs, guides, key pages.
A companion llms-full.txt inlines the full text of those pages, so a model can answer from your content without crawling at all.
