Short answer: llms.txt is a proposed text file placed at the root of a website, such as yoursite.com/llms.txt, that gives AI tools a short, structured summary of the site and links to its most important pages in Markdown. It is not an official web standard, Google has said it does not use it for search, and support among AI companies is limited. It is cheap to add, but it will not replace good content, structured data and a clear site.
As AI search grows, new ideas for helping AI understand websites keep appearing. llms.txt is one of the most talked-about, so it is worth understanding without hype.
