llms.txt is a simple Markdown file at your site root that gives AI
answer engines — ChatGPT, Perplexity, Google AI — a clean, canonical summary of what your site is
and where the important pages live. Paste your URL and get one drafted from your real content, free.
Free. No login. Drafted live from your page — review before publishing.
It's an emerging convention (like robots.txt, but for large language models): a
human-readable Markdown file at yoursite.com/llms.txt that summarizes your site and lists
your key pages, so LLMs quote you accurately instead of guessing. It won't rank you on its own — but
paired with real JSON-LD structured data and crawlable HTML, it's part of being citable by AI.
