About LLMS.txt Explorer
Bridging the gap between websites and AI through the llmstxt.org standard
Our Mission
We're building the world's most comprehensive directory of websites that implement the llms.txt standard, making it easier for AI systems to understand how they should interact with web content responsibly.
Data Collection Process
We systematically crawl the top 1 million websites every few days,
scanning for llms.txt and
llms-full.txt files.
Each discovered file is validated against the official specification using the
llms_text module,
ensuring quality and compliance with the standard.
Our data is enriched with website categorization, quality scores, and topic rankings to provide comprehensive insights into how different industries adopt the standard.
The llmstxt Standard
The llmstxt standard provides a structured way for website owners to communicate instructions and permissions to Large Language Models and AI agents.
It complements existing standards like robots.txt
(for crawlers) and sitemap.xml (for discovery),
but focuses specifically on AI interaction guidelines.
Files contain key-value directives specifying interaction models, data usage policies, contact information, and more to foster responsible AI interactions.
