AI crawlers face varied robots.txt rules; Distill prioritizes explicit opt-outs

Hybrid Forge Lab, the creators of the Distill URL-to-Markdown API, have analyzed robots.txt files from 37 major websites to understand how AI crawlers are treated. Their findings indicate that while specific AI crawler user agents like GPTBot and ClaudeBot are frequently disallowed, Google-Extended and Applebot-Extended are less commonly explicitly blocked. The lab's parser prioritizes explicit directives for 'DistillBot' and then checks for any AI crawler disallowances, ensuring content is not used for LLM training if explicitly refused by the site owner. AI
