Design Language Studio

Design a complete design language your AI actually follows.

Compose color, typography, spacing, radius and shadow in one guided studio. Preview the whole system live, then export CSS, Tailwind, JSON and AI agent rules — so every AI-generated screen stays consistent and on-brand.

Why a design language

AI writes UI fast — but consistency breaks first.

Colors drift, spacing turns arbitrary, and components stop feeling related. Design Language Studio fixes the root cause: it turns your visual decisions into one structured, machine-readable source of truth.

Define your system once, preview it on real UI, and hand AI coding tools the exact constraints they need — instead of hoping they remember.

Features

Everything you need to define a design system.

Six connected token systems and a live workspace — one coherent language, not six disconnected tools.

Color systems

Generate accessible, semantic color palettes with light and dark roles and built-in WCAG contrast checks.

Typography & pairing

Build mathematically consistent type scales and pair heading and body fonts that work in harmony.

Spacing rhythm

Create a structured spacing scale and semantic spacing roles that keep every layout in rhythm.

Surface: radius & shadow

Set corner-radius personality and an elevation-driven shadow system for believable, consistent depth.

Live preview canvas

See your tokens applied to a real product screen, a full component set and a live token sheet — across desktop, tablet and mobile.

Health checks

Real-time scoring for contrast, hierarchy, progression and consistency catches problems as you design.

How it works

From blank canvas to AI-ready system in four steps.

  1. 01

    Compose your tokens

    Move through Color, Typography, Spacing and Surface — each step focused, each choice reflected instantly.

  2. 02

    Preview it live

    One shared canvas shows the whole language together as a real product UI, not isolated swatches.

  3. 03

    Check the health

    A live health rail flags contrast, hierarchy and consistency issues before they ship.

  4. 04

    Export for your build

    Export the complete system as CSS, Tailwind, JSON, or AI agent rules — then build with confidence.

The workspace

Built like a real design tool.

  • Guided step tabs for color, type, spacing and surface
  • A focused control inspector for each dimension
  • One live canvas — product, components and tokens views
  • Desktop, tablet and mobile previews
  • A live health rail scoring your system as you work
Open the Studio
Export

One design language, every format your stack uses.

Export the whole system at once — for your codebase and for the AI tools that build with it.

CSS variables

A clean :root block of custom properties.

Tailwind theme

Tailwind v4 @theme and v3 config.

JSON tokens

Portable design-token JSON.

AI prompt

A paste-in brief for ChatGPT, Claude or v0.

AI agent rules

AGENTS.md, CLAUDE.md or .cursorrules.

FAQ

Frequently asked questions

What is a design language?

A design language is the single set of rules — color, typography, spacing, radius and shadow — that makes every screen feel like one product. Design Language Studio lets you define those rules as structured design tokens and export them.

How does it help with AI-generated UI?

AI coding tools forget your design rules between prompts. The Studio exports your tokens as machine-readable constraints — AI prompt text and agent-rules files like AGENTS.md or CLAUDE.md — so AI-generated frontends stay visually consistent and on-brand.

What can I export?

CSS custom properties, Tailwind v4 and v3 themes, JSON design tokens, a paste-in AI prompt, and AI agent rules files. The combined export bundles your whole design language at once.

Do I have to use every step?

No. Each step has sensible defaults, so you can customize only what you need and still export a complete, coherent design language.

Is it free to use?

Yes — you can compose and export a full design language for free.

Standalone builders

Prefer one piece at a time?

The Studio runs on the same engines as our six focused builders. Start with a single token system — your work carries straight into the Studio.
