Drop-in design systems your AI coding agent can read
Figma For AI Agents is a innovative tool designed to bridge the gap between visual design systems and AI-powered coding agents. It offers getdesign.md, a curated collection of DESIGN.md files that encode a brand's visual language—including colors, typography, spacing, components, and motion—in a format that AI models like Cursor, Claude Code, Lovable, v0, or Bolt can interpret. By integrating these files into AI coding projects, developers and designers can ensure their AI-generated UI outputs are consistent with established brand aesthetics, resulting in more polished and professional interfaces. The platform features over 60 ready-made brand files, with options to request new ones or generate custom designs, making it highly adaptable for different brands and projects.
