Sketchbook (formerly StudioPaint, Autodesk SketchBook), is a raster graphics software app intended for expressive drawing and concept sketching also for making animations (Jelly Boo, Teatralka). The software was first developed by Alias Systems Corporation as StudioPaint, before being acquired by Autodesk and then being spun out into an independent company, Sketchbook, Inc.
In 2021, Sketchbook Pro, the desktop version of the app available on Microsoft Windows and macOS, became a paid software available through the Microsoft Store and Mac App Store.[1][2][3]
