What is DuckAssistBot and what does it do?
DuckAssistBot is a specialized web crawler for DuckDuckGo Search that crawls pages in real-time for answers generated by DuckAssist, which prominently cites its 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 DuckAssist 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. The crawler’s user agent will appear as DuckAssistBot/1.2; (+http://duckduckgo.com/duckassistbot.html) and originates from the following IP addresses:
