What is llms.txt?

A roadmap for AI that reads your site

llms.txt is an emerging standard (inspired by robots.txt) that tells large language models which pages on your site are most important. When AI crawlers see /llms.txt, they use it to understand your site structure and prioritize your content in generated answers. Without it, AI models guess — and often get it wrong.
