Streamlined digital painting for illustrators
PaintTool SAI delivers a focused digital painting environment built specifically for illustrators and comic artists. The program centers on responsive pen input, smooth line rendering, and natural brush behavior that feels consistent during detailed work. PaintTool SAI uses a straightforward license model with a free trial followed by a one-time purchase, avoiding subscriptions. Its lightweight design and clear interface make it approachable while still offering the precision many artists expect from dedicated drawing software.
PaintTool SAI provides a versatile brush engine that includes pen, airbrush, and watercolor-style tools, all customizable for size, density, and texture. PaintTool SAI supports pressure-sensitive tablets, enabling controlled strokes and subtle shading transitions. The layered workflow allows users to create, reorder, lock, and adjust opacity with ease, along with blending modes for refined compositions. Selection tools and brush-based erasing help isolate edits without disrupting the full canvas, while anti-aliasing keeps lines crisp and smooth.

Support for common formats including PSD ensures compatibility with broader creative workflows.
