About
July 2026 paper introducing AI Prototyper, an open-source Figma plugin that turns natural-language screen descriptions into fully editable prototypes. Its pipeline decomposes a request into reviewable features, retrieves components from a fixed 32-primitive library, generates schema-constrained instances, and renders native Figma layers with auto-layout.
Summary
Why AI Prototyper Adds New Signal:
1. Editable design-time generation: Produces native Figma layers rather than flattened images or disposable code previews
2. Human checkpoint: Lets users review, delete, reorder, and extend decomposed features before rendering
3. Grounded component generation: Uses two-stage retrieval and schema validation over a fixed component catalog
4. Multilingual workflow: Demonstrates correctly labelled Thai, English, and Mandarin interfaces, with additional Malayalam testing
5. Preliminary evaluation: Reports higher prototype throughput and stronger expert ratings than manual Figma work, while acknowledging small student and evaluator samples
