Another interesting aspect is the application-wide scratchpad which digital painters use as a color mixing panel. By doing so, one can immediately notice errors in perspective and composition. One of the more interesting features is the ability to mirror the drawing board with the click of a button. Graphics editors are able to zoom and rotate the drawing canvas easily using sliders that can be configured to the keyboard easily. This is beneficial to those who seek to use this program for graphics editing, as assets can be moved between documents. Once users open SAI, the first thing that can be noticed is that this program allows for multiple documents to be opened simultaneously. This program was initially developed for Japanese users but an official English translation patch has come out in recent years. It is a very powerful graphics editor and painting software while remaining surprisingly lightweight, clocking in at around 2MB.

Paint Tool SAI, also known simply as SAI, is a creative software for Microsoft Windows (98, Me, 2000, XP, Vista, 7, 8, 8.1, and 10) that was developed by SYSTEMAX Software.
