sketch-based design input

A design methodology where hand-drawn or digital sketches serve as primary input for AI systems to generate refined UI layouts and production code. Enables rapid iteration from initial ideation to functional prototypes.

Key characteristics:

• Accepts freehand sketches or rough digital drawings as input
• Generates layered, production-ready UI designs and code within seconds
• Reduces manual design-to-dev handoff time

Implementation example:

• Google Stitch 2.0: AI design agent powered by Gemini 3.0 Pro that converts sketches into professional UIs with heatmap predictions for user attention. Produces code in under 60 seconds.
