What is DuckAssistBot?

DuckAssistBot is an AI assistant crawler. DuckAssistBot is a web crawler for DuckDuckGo Search that crawls pages in real-time for AI-assisted answers, which prominently cite their sources. This data is not used in any way to train AI models.

DuckAssistBot helps decide whether you show up in AI answers. It fetches and indexes pages so its assistant can cite them in responses, which means the content it can reach is the content that can be quoted, linked, and recommended to users. For generative engine optimization, keeping DuckAssistBot allowed is important: block it and you effectively opt out of being cited on that AI surface.

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.

How to handle DuckAssistBot

Most sites keep DuckAssistBot allowed, because blocking it can remove your pages from the AI answers and search results it powers. Only disallow it if you specifically want to opt out of that surface.

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

User-agent: DuckAssistBot
Disallow: /

DuckAssistBot generally honors robots.txt directives.

Examples

  • After publishing a new comparison page, a marketer checks whether DuckAssistBot has fetched it so the content can appear in AI answers.
  • An SEO lead keeps DuckAssistBot allowed in robots.txt to preserve visibility in AI-powered search.
