DESIGN:OS Studio is a high-quality, FREE Figma alternative built for AI, released as FREE + source-available (PolyForm Shield).
The problem: one mask type is not enough for photos, icons and textures.
The approach: v0.7.7 adds three mask types: Alpha, Vector and Luminance.
The result: you cut by the alpha channel, by vector, or by the luminance of the mask layer.
