Full definition
Similar in spirit to robots.txt or sitemap.xml, llms.txt is meant to be human- and machine-readable markdown: typically an H1 site name, a blockquote summary, and ## sections of curated links. It is a community convention, not a formal internet standard.
Publishing llms.txt does not guarantee every model will use it, but it provides a clear crawlable signal of preferred context. Pair it with open crawler access and solid public content. See robots.txt and AI Crawler.
Example
https://example.com/llms.txt might start with “# Example Co” and a one-line summary, then ## Docs and ## Pricing with absolute https links.
