The llms.txt standard is taking off. This is where you see it happening.
llms.txt is an open standard that tells AI search engines — ChatGPT, Claude, Perplexity, Gemini — what your website is about. A simple markdown file at /llms.txt gives AI a structured map of your content, services, and documentation. Think of it as robots.txt for AI.
1496+ companies have already adopted it. The average implementation has 17 sections and 1029 lines — but the best ones go far beyond that. This directory tracks every public llms.txt we can find, analyzes its structure, and shows you who's taking AI discoverability seriously.
