# Generate a complete design system from a single prompt

> Flash DSM uses parallel AI workers to build every layer of your design system - colors, typography, spacing, shadows, and components - from one sentence. Here's exactly how it works.

## The 45-second design system

Most design systems take weeks to bootstrap. You start with a Figma file, pick colors manually, argue about type scales, decide on spacing increments, and repeat this for every client or project. Then your developer asks why the CSS doesn't match, and the whole loop starts over.

Flash does something different. You describe what you're building in plain language:

> "A fintech investment platform - serious, trustworthy, modern dark mode"

And in about 45 seconds, you have:

- A full **color palette** - primary scale (50–900), secondary, neutral, semantic states (success, warning, error, info), gradients, dark mode variants
- A **typography system** - display and body font pair from Google Fonts, with full size, weight, line-height, and letter-spacing tokens
- **Spacing** - a consistent 4px-base scale from xs to 4xl
- **Border radius and shadow** - matched to the product vibe (sharp and secure for fintech; round and friendly for wellness)
- **Motion** - timing and easing tokens for UI transitions
- **8–14 domain-specific components** - named, specced, and mapped to the tokens above

## How the pipeline works

Flash runs a LangGraph AI pipeline with parallel Claude workers. Instead of one big prompt that tries to do everything (and usually gets generic results), each layer has its own specialized node:

```
Input prompt
     │
     ▼
DNA + Strategy    ← Claude Sonnet - brand archetype, aesthetic intent
     │
     ├─── Colors         ← Sonnet - primary/secondary/neutral/semantic
     ├─── Typography     ← Haiku - font pairs, size scale, weights
     ├─── Spacing        ← Haiku - consistent scale, grid
     ├─── Radius/Shadow  ← Haiku - border radius tokens, elevation
     ├─── Motion         ← Haiku - timing, easing
     ├─── Components     ← Sonnet - domain-specific component specs
     └─── Preview        ← Haiku - layout blueprint
          │
          ▼
     Assembler → Exportable design system
```

The DNA + Strategy node runs first and produces a brand archetype. Everything downstream pulls from that archetype, which is why a "fintech platform" gets a completely different output from a "botanical garden brand" - not just different colors, but different typographic choices, different spacing ratios, different component conventions.

## Import instead of prompting

Not starting from scratch? Flash can also extract design DNA from:

- **A live website URL** - Flash fetches the page, analyzes the CSS, and extracts the existing color palette, type choices, and spacing patterns
- **A Figma file** - connect your Figma account and import variables and styles directly
- **An image** - paste a screenshot or moodboard; Flash uses Claude Vision to read the visual language

This works especially well when you're replatforming: scan the existing site, clean it up in the editor, and export clean token files your developers can drop in.

## What you export

Every design system Flash generates is exportable as production-ready files:

| Format | Use case |
|--------|----------|
| `tokens.css` | CSS custom properties, drop into any project |
| `tailwind.config.js` | Tailwind theme extension - tokens become utility classes |
| `tokens.json` | Tokens Studio format - round-trips with Figma |
| ZIP bundle | Full project scaffold for React, Next.js, Vue, or Svelte |
| GitHub push | Commit tokens directly to your repo |
| Cursor rules | Inject token context into your AI coding assistant |

The CSS and Tailwind outputs are the same files you'd write by hand - no proprietary runtime, no lock-in.

## Try it

The fastest way to understand Flash is to use it. Type a one-sentence description of your product on the homepage and watch the pipeline run. The whole thing streams in real time so you can see each layer materialize.

New accounts get a one-time credit grant - enough to try it with a real project before you need a plan.
