llms.txt explained — the new convention for AI.
llms.txt is a markdown file at your root that tells LLMs what your site is. Here's what it does (and doesn't).
Overview
llms.txt is a growing convention: a markdown file at /llms.txt that summarises your site for LLMs. No major LLM enforces it yet, but it's cheap to ship and forward-looking.
What's in it
A heading with your site name, a short description, a list of main pages with one-sentence summaries, brand voice notes, contact info.
What it doesn't do
It doesn't override your robots.txt. It doesn't guarantee LLMs read it. It doesn't replace structured data.
Why ship it anyway
It's a 5-minute file. If/when the convention gets adopted, you're ready. If not, you've lost nothing.
