Awesome Design.MD - Apply Famous Website Design Systems to Your Own Site

DESIGN.md is a concept introduced by Google Stitch, a text-based design document designed to let AI agents generate consistent UI.

Without Figma or a separate JSON schema, simply copying a single markdown file into the project root lets an AI coding agent instantly recognize and implement the UI style. While the existing AGENTS.md covers functional aspects, DESIGN.md focuses on defining visual appearance and feel.

Key features are as follows:

• Extensive collection: Design systems from 60+ famous services including Claude, Vercel, Stripe, Notion, Figma, and more
• Standardized structure: Composed of 9 standard sections covering color palette, typography, component styling, layout, responsive behavior, and more
• Efficient workflow: Drop the DESIGN.md of the site you want into your project and instruct the AI to reference it, and it can instantly generate a UI similar to the original

For each site, a set of DESIGN.md and preview.html for visual confirmation is provided together, helping the AI grasp the design intent more accurately.
