Free LLMs.txt Generator For Your Website

Our tool crawls your website, maps your highest-value pages, and builds a fully-structured LLMs.txt file, so AIs/LLMs like ChatGPT, Claude and Perplexity can find, understand and cite your content.

It took a lot of work fine-tuning the generator so you get a custom, actually effective version of the file.
FYI: The business you're building is worth the work.
