ClaudeBot (Anthropic crawler)

Definition

ClaudeBot is Anthropic's web crawler, identified by the user-agent 'ClaudeBot'. It collects publicly available web content that may support the development and improvement of Anthropic's Claude models. Website owners can permit or restrict its crawling through robots.txt rules.

ClaudeBot follows robots.txt conventions, and Anthropic publishes documentation so publishers can identify and manage the bot. Like other training-oriented crawlers, it gathers text at scale; the decision to allow it shapes whether your content contributes to Claude's knowledge base.

Anthropic also operates separate agents for user-initiated fetching, so blocking ClaudeBot does not necessarily block every Claude-related request. For brands aiming to be represented accurately when people ask Claude about their category, Acromatico weighs crawler permissions against the value of appearing in those AI-generated answers.
