Short answer

An AI crawler is an automated bot that fetches web pages either to train AI models or to retrieve content for answering users in real time. Examples include GPTBot, ClaudeBot and PerplexityBot. Site owners can allow or block specific crawlers through robots.txt, balancing content protection against visibility in AI assistants and AI search answers.
