Chrome: One of the best features in the search engine DuckDuckGo is the instant answers shown at the top of the results page. If you find yourself more attached to Google for web searches, but want the instant answer feature, DuckDuckGo Zero-Click Info is a Chrome extension that stuffs those results right in your Google searches.
DuckDuckGo Zero-Click Info adds a small results box to the top of your Google search results that gives you a one or two sentence answer to your search. It also gives you direct links to the main article pages so you don't have to click around to find what you're looking for.
Google may eventually roll out its similar Knowledge Graph feature in Australia, but DuckDuckGo's results are still more expansive and covers more topics. It's a handy little extension that offers one of the best features of DuckDuckGo right in your Google results. You can find a bunch of the query shortcuts over on DuckDuckGo's Goodies page.
