llms.txt
01 Definition
llms.txt meaning: A proposed text file that gives AI models a curated guide to a site's content.
llms.txt is a proposed standard file placed at a site's root that offers large language models a concise, structured guide to key pages and content. Its goal is to help AI tools find and use accurate information. Adoption is voluntary and early, and major AI providers do not officially guarantee they read or honor it.
Why it matters
How llms.txt fits the work
As AI tools consume site content, llms.txt is an attempt to give owners a clearer way to point models toward their best, canonical information.
In context
A documentation site added an llms.txt listing its main guides and API reference so AI assistants could locate authoritative pages more easily.
Practical note
It is an unofficial, emerging convention, not a rule engines must follow. Do not treat it as a ranking factor or assume it controls how AI systems use your content.
