Question 1

What is llms.txt?

Accepted Answer

llms.txt is a proposed standard (similar to robots.txt) that provides a structured markdown document at /llms.txt on a website, giving AI language models a concise, human-readable summary of the site's content, purpose, and key documentation links — optimized for LLM context windows.

Question 2

Should I add llms.txt to my website?

Accepted Answer

If you want AI assistants (ChatGPT, Claude, Perplexity) to accurately represent your product, documentation, or services, adding an llms.txt helps. It's especially valuable for developer tools, SaaS products, and documentation-heavy sites where AI-generated answers about your product matter.
