llms.txt
A proposed text file that summarizes important website pages for AI assistants and large language model crawlers.
llms.txt is an emerging AI SEO and GEO convention for telling AI assistants which pages best describe a site, product, documentation set, or knowledge base. It is usually published at /llms.txt.
Unlike robots.txt, llms.txt is not an access-control standard. It is a discovery and guidance file that can point AI systems toward canonical, evergreen, and high-quality resources.
