What is klad?

klad is a two-dimensional painting and animation application designed for collaboration between a human artist and a coding agent. The human uses the desktop editor with a graphics tablet to draw strokes, while the coding agent uses the command line interface to apply the same brushes to the same canvas. Both users see each other work in real time.

Unlike image generation tools that output static pixels, klad stores every mark as editable data. Each stroke records its path, pressure, brush type, and color. Users can select any element hours later to change its color, move it, or delete it. The software supports both raster style painting and vector shapes, including gradients, glows, and text rendered from fifty included fonts.

The application includes twenty four brushes with an editor, layer management, masks, clipping modes, visual effects, and an animation timeline featuring onion skinning, clips, automatic in between frames, and inverse kinematics for bone rigging. Drawings export as PNG files, sprite sheets, or directly into Godot. The project runs on macOS with full pen pressure and tilt support, and compiles on Linux and Windows. It is released under a source available license that allows free personal and commercial use for companies earning under five hundred thousand euros annually.
