llms.txt is the file that tells AI engines (ChatGPT, Perplexity, Google AI) what your site is and which pages matter — so they can read and recommend you correctly. Fill in a few fields, get a ready-to-upload file.
Fill in the fields and click Generate — your llms.txt appears here.
Upload the file to your site root as /llms.txt (e.g. yoursite.com/llms.txt).
An llms.txt is one signal. Our free GEO audit checks all of them — robots.txt, schema, AI discovery files — and shows whether ChatGPT and Perplexity actually recommend you.
