llms.txt
A Simple Guide to the AI Content Index File
llms.txt is a proposed standard (llmstxt.org) for helping large language models read your site. It’s a curated Markdown file at your domain root that lists your most important pages with short, clear descriptions — a clean index AI systems can use to find and interpret your content. Unlike robots.txt, it isn’t an access-control or opt-out mechanism: it doesn’t block crawlers, govern training, or set licensing terms. It simply makes your best content easier for LLMs to discover and use.
