What is DuckAssistBot?

DuckAssistBot is DuckDuckGo's AI-powered crawler that indexes content specifically for DuckAssist, the AI-generated instant answer feature in DuckDuckGo search results. When DuckDuckGo detects a query that can be answered with a summarized response, DuckAssist generates the answer from content indexed by this bot.

This is separate from DuckDuckBot (the regular search crawler) and specifically serves the AI answer generation pipeline. DuckAssistBot has moderate crawl rates and targets content that lends itself to summarization — articles, documentation, FAQs, and informational pages.

Being indexed by DuckAssistBot means your content can appear as an AI-generated instant answer at the top of DuckDuckGo results, providing significant visibility to DuckDuckGo's privacy-conscious user base.
