What is llms.txt?
Also called: LLMs text file
llms.txt is a proposal for a text file in the root of a website. In Markdown it briefly sums up what the site is about and links the most important content for AI agents.
Example
At example.com/llms.txt there is one paragraph about the company and a list of links to pricing, documentation and contact.
For pros
The proposal was published by Jeremy Howard. It is not an official web standard like robots.txt, and no provider has to read the file. Many documentation platforms generate it automatically, and coding agents in particular use it. Google states explicitly that no new machine-readable files or AI text files are needed for AI Overviews and AI Mode. llms.txt does not control access either; robots.txt remains responsible for that.
