Every layer of the design system,
automatically extracted

The engine scores each finding against real evidence — only tokens that appear enough times to be intentional make it into your report.

🎨
Colour Tokens

Full palette with semantic roles — background, surface, text, accent, status. Includes WCAG contrast ratios.

Typography Scale

Font families, weights, sizes, line-heights, and letter-spacing — voted from 6 samples per tag for accuracy.

Spacing & Layout

Spacing scale built from real padding and gap values. Grid columns, container widths, and breakpoints detected.

Components

Up to 8 button variants, 5 input types, navigation structure, and content module patterns — all with their visual properties.

Page Patterns

Hero, feature grid, testimonial, pricing, CTA — each pattern scored by confidence so you know what the site actually uses.

Motion & Craft

Motion personality classified from CSS transitions. UI craft signals like border-radius consistency, shadow layers, and micro-interactions.

Six prompts, ready to paste into any AI tool

Each prompt embeds the full extracted DNA. Drop it into ChatGPT, Claude, Gemini, v0, Cursor, or Lovable and start building.
