DuckAssistBot
DuckAssistBot crawls pages in real time for DuckDuckGo's AI-assisted answers, which cite their sources. DuckDuckGo says the data is not used to train AI models. Disallowing it removes you as a source for those answers but does not affect your organic DuckDuckGo search rankings.
What it does
DuckDuckGo says DuckAssistBot is a web crawler for DuckDuckGo Search that crawls pages in real time for its AI-assisted answers, which prominently cite their sources. It says this data is not used in any way to train AI models.
Publishers can opt out of being a source for AI-assisted answers by disallowing DuckAssistBot in robots.txt. DuckDuckGo says the change takes effect after 72 hours and does not affect organic search rankings or whether a site appears in its search results.
