Generate transforms images into generated drawings. There are five possible modes you can choose from. Behind each mode, there are a number of unique algorithms that analyse the image and generate in real time a unique drawing that you can use for your illustrations, collages, tattoos, and compositions. Other "similar" photo-editing applications simply applies filter to the pictures, showing you only the final result of your images. By contrast, Generate shows the magic of the entire generative process in front of your eyes, giving you the possibility to experience the creation as a spectator.
