InkForge vs Sumo Paint

InkForge is a GPU-backed raster drawing app with a stamp-based brush engine, layers, selection tools, animation and an AI panel. Its six procedural texture tips support pressure control of brush size and opacity. The app offers unlimited layers, twelve blend modes, clipping masks and non-destructive layer effects. Its frame-by-frame timeline supports duplication, onion-skinning and adjustable FPS, with GIF or WebM export. Native .inkforge projects preserve layers and frames; export formats include PNG, JPEG and TIFF. The AI panel lists fourteen modes, including style transfer, sketch-to-painting, inpainting and background removal. Generation can use Gemini or Replicate with the user's own key, or a local ComfyUI graph. The maker says keys are stored locally and the ComfyUI path stays on the machine. InkForge is free and open source under the MIT license. It lists Windows, macOS and Linux support, while download requirements specify Windows 10+ and macOS 13+. The maker describes cross-platform development as active and the native macOS build as the original Swift implementation.
