PaintTool SAI - The first knowledge sharing application in Vietnam

Pros: PaintTool SAI is legendary for how fast its brush engine is. Many brushes, you can blend better. The layout makes this software very easy to use.

Cons: Lack of guides and rulers. It’s just not available for Mac which makes it very unfair for those Mac users to pay.

Overall: It wasn’t until I used Paint Tool SAI, that I had fun learning to use my XP-Pen Deco 01 V2 graphic tablet to draw. That’s because the program is compact, with just enough features that are easy to learn and use.
So, you’ll find things like line-art layers with simple vector tools, masks, clipping and layer groups, but you won’t find guides (except when transforming a selection) or rulers. But not everyone needs extra design features like that, just to draw what they want.
PaintTool SAI is a good application for a notebook or laptop, where you just want to draw something on the spot, and save it as a PSD file to import to other programs later. For what it is, SAI is a digital painting program, but if you want extra features like guides, animation, or even filters, this is not for you.
