#AI crawlers
AI crawlers are the automated bots that AI companies use to fetch web pages, either to train models or to answer user questions in real time. Each one identifies itself with a user-agent name, such as GPTBot, ClaudeBot or PerplexityBot. Site owners can allow or block them in robots.txt, and sometimes they are blocked by accident by a firewall or CDN setting. Knowing which bot does what helps you decide which ones to let in. Articles under this tag cover crawler names, access rules, logs and common mistakes.
