Who is Using llms.txt

llms-text.com generates llms.txt files, the simple guide that tells AI crawlers such as GPTBot and ClaudeBot what a domain contains and which pages matter. A URL entered in automatic mode produces the file, or it can be built by hand with custom sections, then previewed live and exported. A larger llms-full.txt file bundles the full markdown of core pages, such as documentation and pricing, so Claude, ChatGPT and Perplexity can cite a product accurately instead of guessing. The file is hosted at the root of a domain where crawlers find it. The aim is better visibility in AI search results, also called generative engine optimization. Standard llms.txt generation has a free tier, and the full scan is a paid extra. Other tools include a validator that checks an existing file, a directory of domains already using llms.txt and a live example to study.
