Scribble Diffusion
Turn rough doodles into polished digital masterpieces using Stable Diffusion image generation.
What is Scribble Diffusion?
Turn Doodles into Digital Art
Scribble Diffusion is a fun, accessible AI art tool that transforms rough hand-drawn sketches into polished, detailed images using Stable Diffusion. You draw a simple doodle, add a text description of what you want, and the AI interprets your sketch as a structural guide to generate a coherent, fully rendered image.
The Power of Sketch-to-Image
Pure text-to-image generation can produce unpredictable compositions. Scribble Diffusion solves this by using your sketch as a structural layout — the AI fills in the artistic detail while respecting the rough shapes and spatial relationships you drew. This gives users much more compositional control than text prompts alone can provide.
- In-browser doodle input with text description
- Sketch guides composition and layout of generated image
- Powered by ControlNet-enhanced Stable Diffusion
- Instant generation with no account required
Key Features
Draw a rough sketch in the browser that guides the composition and layout of the generated image.
Combine a text description with your sketch for precisely controlled image generation.
Results appear quickly without needing an account, API key, or any technical setup.
Built on open-source Stable Diffusion with ControlNet — the code is publicly available.
More control over image composition than text-only generation, even with rough stick-figure sketches.
Who Uses Scribble Diffusion?
Quickly visualize a concept or composition idea by sketching it and generating a polished version.
Show students how AI image generation works through a hands-on, intuitive sketching interface.
Rapidly prototype character and environment concepts from rough structural sketches.
Play with AI art generation in a uniquely tactile, drawing-based format.
