Google Squared and Wolfram Alpha are similar in the sense that they are both special search tools that attempt to acquire and extract structured data. They both have simple and similar search interfaces (refer to the images above) in which the search box is the predominant object and is centred on the page for easy and direct access.
Even though they were both created for similar purposes, their approaches in accomplishing this challenging task are very different from each other.
