Does ChatGPT use llms.txt?

The llms.txt standard was proposed as a way for website owners to provide a curated list of important pages for AI systems and automated tools.

While an llms.txt file may help organize important content, there is no public evidence that adding one directly improves citations, recommendations, rankings, or AI visibility.

The value of an llms.txt file comes primarily from helping highlight useful resources such as documentation, FAQs, product pages, and research content. The quality of the underlying content remains far more important than the existence of the file itself.

Founders should view llms.txt as a documentation aid rather than a visibility shortcut.
