Using designs from artists and machine learning Google built this tool. AutoDraw is similar to text predictor. But of course, it is much more than that. It predicts what user wants to draw and shows predicted results to user from which he can choose desired sketch. It has hundreds of images in its database and able to predict almost every image. The best thing about AutoDraw is that it is available on every platform. But it is still in its development stage and many images and improvements are yet to be added.
