What is DuckAssistBot and what does it do?
DuckAssistBot is a web crawler for DuckDuckGo Search that crawls pages in real-time for our AI-assisted answers, which prominently cite their sources. This data is not used in any way to train AI models.
If you’re a publisher, you may opt out of being a potential source for AI-assisted answers by modifying the robots.txt file for your domain(s). Once you’ve updated the file to disallow the DuckAssistBot user agent, the change will take effect after 72 hours and DuckAssistBot will stop crawling your site. Publishers can contact us at [email protected] with any opt-out problems. Opting out of DuckAssistBot does not impact organic search rankings and will not affect whether or not websites appear in our search results.
The crawler’s user agent will appear as DuckAssistBot/1.2; (+http://internal-search.workmagic.io/duckassistbot.html) and originates from the following IP addresses:
