Paint Tool SAI and GIMP don’t exactly overlap, so some of these categories will be a little bit different than usual because I’m guessing you’re most curious about how they compare to digital painting tools.Īt first glance, Paint Tool SAI’s brushes are fairly simple.

When comparing software, it’s important to outline the criteria that I’m using in the review. GIMP is a much better all-around image editor that includes some decent painting options, while Paint Tool SAI is an excellent digital painting app with almost no other image editing capabilities at all.
