What is Claude-User?

Claude-User is an agent operated by Anthropic designed to act as a bridge between the Claude AI model and the live web. Unlike crawlers used for model training, this agent is triggered specifically by user-initiated requests, allowing the AI to fetch and summarize current information from websites to provide accurate, up-to-date answers. It is part of Anthropic's suite of documented robots, which includes separate agents for model training and search indexing.

Helpful — This bot operates on behalf of end-users to provide real-time information and respects standard web protocols like robots.txt.

What we read

Why it crawls your site

The primary purpose of Claude-User is to provide the Claude AI with the ability to access and process external web content in real-time when a user asks a question that requires current information. By using a distinct user agent, Anthropic allows website administrators to distinguish between traffic intended for model training and traffic intended for direct user assistance. Site owners can manage or restrict this agent's access via their robots.txt file, ensuring they maintain control over how their content is surfaced in user-driven AI interactions.
