What is PaintTool SAI?
PaintTool SAI is a drawing and painting application for building illustrations with a digital pen. Brushes such as pen, airbrush and watercolor, adjustable brush pressure, layers and selection tools support sketching, coloring and finishing artwork. PSD and BMP export let you move finished work into another application.
The linked package is SYSTEMAX's English 32-bit full installer for Version 1.2.6-Beta.3, dated January 27, 2025. The publisher distributes it as a test version correcting a rare Version 1.2.5-and-earlier bug that could lose a saved file when another program accessed it during saving. It is not the separate Version 2 technical preview.
Version 1 focuses on painting rather than general photo editing: it does not offer direct printing or text and gradient insertion. Softonic describes a 31-day trial followed by a paid license. At retrieval, SYSTEMAX's reduced-service notice reported interrupted license purchasing and a staged service-restoration plan; check the publisher's notice before relying on a new purchase. The gallery image illustrates the source-listed application workspace; its exact build is not identified.
What it offers
- Draw with pen, airbrush and watercolor brushes and adjustable pressure response.
- Organize artwork with layers and select areas for editing.
- Choose and adjust colors with color controls and saved palettes.
- Export artwork as PSD or BMP for use in other applications.
Good to know
- The selected Version 1.2.6-Beta.3 package is a publisher-designated test version, not a stable-release claim.
- Version 1 lacks direct printing and text or gradient insertion; photo-editing features are limited.
- The trial is limited to 31 days; continued use requires a paid license. Publisher license-purchase services were interrupted at retrieval.
