Discover Websites using llms.txt

We’re excited to announce that BuiltWith now tracks websites that have implemented llms.txt — a new standard that allows site owners to declare how they want their content to be used by AI and LLMs. Just like robots.txt but for large language models, llms.txt gives websites more control over how their data is accessed and utilized. You can now explore a full downloadable list of domains that have added this file to their root directories.
