Curio

Curio is a design style library for AI agents that provides DESIGN.md files to apply professional aesthetics to websites, slide decks, and reports.

Curio provides a library of over 2,400 design systems for use with AI agents. Users select a visual style and provide its DESIGN.md file to an AI to format websites, slide decks, or reports. Each design system contains thirteen spec sections including colors, typography, buttons, spacing, and motion techniques. Once a style is obtained, users download the documentation or connect via MCP to share it with AI models. It includes styles spanning various eras, brands, and visual moods. It supports integration with AI tools that read links or accept file uploads.
