What is llms.txt?
llms.txt is a plain-text file that gives AI agents a concise map of your site: what the product is, which pages matter, and where documentation or machine-readable resources live.
What llms.txt is for
Think of llms.txt as a readable guide for AI systems and agents. It does not replace your sitemap, robots.txt, or documentation. It gives crawlers and agent tools a short, structured entry point so they do not have to infer everything from navigation.
A simple llms.txt shape
# ExampleCo
> One-sentence description of what the company does.
## Pages
- [Home](https://example.com/): product overview
- [Pricing](https://example.com/pricing): plans and limits
- [Docs](https://example.com/docs): API and integration docs
- [Methodology](https://example.com/methodology): how claims are measured
## Machine-readable data
- https://example.com/data.jsonWhat llms.txt is not
- It is not a ranking switch.
- It is not a permission file; use robots.txt for crawler rules.
- It is not a substitute for useful HTML pages.
- It is not enough to make an assistant recommend you.
