Design direction for AI-generated UI

21 style guardrail files that give LLMs the context to build tasteful, consistent interfaces.

What's New

Every style is now a complete design system — not just colors and fonts.

New Sections

Dark Mode, Responsive & More

Every style now includes dark mode guidance, responsive behavior, content voice, icon direction, and accessibility rules.

21st Style

Freeform

No prescribed aesthetic — meta-guardrails that teach how to develop your own visual voice and signature element.

CLI

One-Command Install

Run npx designbrief to auto-detect your tool and install. Supports Claude Code, Cursor, Windsurf, Copilot, and Codex.

Design Education

Learn Why, Not Just What

Every style explains the psychology behind its choices — why certain fonts feel trustworthy, why specific spacing creates calm.

Everything you need

Guardrails, not specs. Style direction that lets AI make great design choices.

21 Curated Styles

From Bauhaus to Freeform — each style is a rich design direction file covering typography, color, spacing, and components.

LLM-Native Guardrails

Not pixel specs, but design direction. Define what kind of font, color, and spacing — the AI makes specific choices within the style’s constraints.

Drop-in Skill

Works with Claude Code, Cursor, Codex, Copilot, and more. One command to install, then just ask for UI.

MIT Licensed

MIT licensed — free for any use. Add your own styles, improve existing ones, or use them as-is.

Complete Design Systems

Every style covers dark mode, responsive behavior, content voice, icon direction, and accessibility — not just colors and fonts.
