What is llms.txt
llms.txt is a proposed format (llmstxt.org) for describing a site in a plain markdown file at the domain root: a title, a short description, and a sectioned list of pages. It isn't an official standard and doesn't guarantee AI citations — it's hygiene that helps AI agents quickly understand a site's structure.
