What is Anthropic AI?

Anthropic AI is Anthropic's AI crawler. Anthropic AI is a legacy Anthropic crawler that collected broad web data for Claude model development. Anthropic has largely consolidated this into ClaudeBot, but the token is still seen in logs and robots.txt files.

Anthropic AI 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 Anthropic AI 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 Anthropic AI 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.

How to handle Anthropic AI

If you do not want Anthropic AI using your content for AI training, disallow it in robots.txt. If you are comfortable contributing to AI systems, leave it allowed.

To control Anthropic AI, add a rule for its user agent to your robots.txt:

User-agent: anthropic-ai
Disallow: /

Anthropic AI generally honors robots.txt directives.

Examples

  • A publisher reviews server logs, sees Anthropic AI requesting long-form articles, and decides whether to allow or disallow it in robots.txt.
  • A site owner adds a Disallow rule for Anthropic AI to keep premium guides out of AI training datasets.
