How I Prototype with AI using Design Systems

Want your AI-generated prototypes to look more consistent, professional, and on‑brand? In this video, I’ll show you how to incorporate a design system into your AI prototyping workflow using Claude Sonnet 4.5. We’ll walk through how to cache a design system into memory, use it as a reference for design consistency, and generate a beautiful, AI‑driven data visualization, automatically style to match the design system. In this tutorial, you’ll learn: 1. How to set up and cache a design system in Sonnet 4.5 in prototypr.ai 2. How the design system is built 3. How to generate a data visualization using the cached design system. I'll also walk through a couple of examples of different user experiences that I built with the design system, including: 1. A Pitch deck for an AI startup 2. Blog post layout 3. MCP Server Component Why design systems matter: Design systems bring structure and visual harmony to your projects. When combined with LLMs, they can dramatically speed up prototyping while keeping your brand style intact. Using design systems like this lead to more consistent outputs. Data Source for the Context WIndow dataset used in the video: artificialanalysis.ai Try this design system out and make it your own by visiting the prototypr.ai Marketplace and importing it into your workspace.

Thanks so much for watching. If you have any feedback about how i can make this design system better, I'd love to hear it in the comments below.
