AI Crawler
An automated bot, operated by an AI company, that visits websites to read their content.
What is AI Crawler?
An AI crawler is an automated bot, run by an AI company, that visits websites to read their content, similar to how a search engine's crawler works but for feeding an AI system instead. For example, when a company trains or updates a chatbot, it may send out a crawler that visits millions of web pages and downloads their text. Site owners generally can identify these bots by name in their server logs, such as GPTBot or ClaudeBot, and can choose whether to allow or block them.
Why it matters
AI crawlers are typically split by purpose into categories such as training crawlers, which gather data for future model versions, and retrieval or "live answer" crawlers, which fetch pages in real time to ground a specific query, plus user-triggered fetchers that activate only when a person explicitly asks an assistant to read a page. Major examples include OpenAI's GPTBot, OAI-SearchBot, and ChatGPT-User, Google's Googlebot and Google-Extended, and Anthropic's ClaudeBot and Claude-User, each independently controllable via robots.txt. Because these bots can generate substantial server load, infrastructure providers such as Cloudflare have built dedicated monitoring and control products, reporting that some AI crawlers issue thousands of requests per single human visitor a site receives from that same AI company's referrals.
