What is Claude Web?

Claude Web is Anthropic's AI crawler. Claude Web is a legacy Anthropic crawler that fetched recent web content for the Claude assistant. Its behavior has largely been folded into ClaudeBot and Claude-User.

Claude Web matters for AI visibility because the pages it collects can shape what large language models learn about your brand, products, and expertise. Allowing it can strengthen how accurately AI systems describe and recommend you, while disallowing it keeps your content out of training data. Either way, knowing Claude Web visits is the first step to managing how your brand shows up in AI search.

Tracking which AI crawlers and agents reach your site, and what they do once there, is the foundation of generative engine optimization. See our guides to AI crawlers and robots.txt to control automated access and protect your AI search visibility.

Promptwatch tracks Claude Web in real time from your server and CDN logs, so you can see exactly when it visits, which pages it requests, and how those crawls relate to citations. Learn more in AI crawler logs.
