Sapiens is a application launcher that allows you to access all your applications using mouse gestures. Rather than setting up a bunch of shortcut keys or a series of mouse gestures, you only need to know how to draw circle with your mouse.
The main difference between Sapiens and your dock is that Sapiens comes with artificial intelligence. It learns from you and predicts the applications you will likely need and offers a visualization of this prediction in an intuitive way. When first installed, you might not get what you want, due to the fact that it knows nothing about your habit. It may takes 2-3 days to have enough brain power to make accurate prediction.
