Compiled and maintained by [ThatDevPro](https://www.thatdevpro.com) as part of the [Awesome-llms-txt](https://github.com/SecretiveShell/Awesome-llms-txt) community list. ## What is llms.txt? `llms.txt` is a proposed standard for websites to declare LLM-readable summaries at a stable URL. Crawlers (GPTBot, ClaudeBot, PerplexityBot) check `/llms.txt` and `/llms-full.txt` to retrieve a curated overview of the site without parsing the full HTML. ## Coverage This snapshot contains 735 unique websites with verified `llms.txt` files, plus an additional ~30 with `llms-full.txt` variants.
