What is LLMs.txt?
LLMs.txt is a simple, text-based sitemap designed specifically for Large Language Models (LLMs) such as ChatGPT, Claude, Perplexity, and other AI-powered assistants. Just as a traditional sitemap (sitemap.xml) helps search engines crawl and index your website, an LLMs.txt file helps AI systems find, interpret, and reference your public content more effectively.
This new standard represents the next step in online visibility — one that extends beyond search engines to include AI models that increasingly shape how people discover and interact with information online.
