AI Website Design —
Extract, Not Guess
Analyze any website's design system in 30 seconds. Colors, fonts, spacing, motion — all in one reusable DESIGN.md.
# Linear Design System
## Visual Theme & Atmosphere
Linear's website is a masterclass in dark-mode-first product design — a near-black canvas where content emerges from darkness like starlight.
## Color Palette
- **Background Primary**: #08090a
- **Text Primary**: #f7f8f8
- **Brand**: #5e6ad2
- **Border**: rgba(255,255,255,0.08)
## Typography
- **Font Family**: Inter Variable
- **Display**: 72px / -1.584px letter-spacing
- **Headline**: 48px / weight 510
- **Body**: 14px / 1.6 line-height
## Component Stylings
- **Button**: rounded-full, bg-indigo-600, px-6 py-3
- **Card**: bg-white/[0.035], border-white/10, backdrop-blur
- **Input**: bg-black/30, border-white/10, focus:border-indigo-400
## Motion Design
- **Transition**: 150ms cubic-bezier(0.4, 0, 0.2, 1)
- **Hover**: border-color shift to indigo-300/35Pain Points
Why is documenting a design system always so time-consuming?
Manual DevTools Digging
See a site with great AI website design? Manually open DevTools, inspect colors, fonts, spacing one by one. Takes 1-3 hours and details are easily missed.
Vague Design Intent
Telling AI tools or contractors "make it feel like Linear" lacks precision. Leads to endless back-and-forth and wasted hours.
Slow Competitive Analysis
Comparing AI website design languages across multiple products requires screenshots, annotations, and manual compilation. Low efficiency.
Capabilities
Nine dimensions, fully deconstructed design system
CSS Variable Extraction
Auto-extract all CSS custom properties into a complete token map
Font Stack Detection
Identify font families, weights, size hierarchy, line-height, and letter-spacing rules
Color Palette Extraction
Extract primary, secondary, text, and background colors with precise HEX/RGBA values
Gradient & Shadow Texture
Parse multi-layer shadows, gradient directions, and color stops
Motion Parameter Analysis
Capture transition and animation durations, easing curves, and delays
Component Style Capture
Complete style definitions for buttons, cards, inputs, badges, and more
Spacing System Recovery
Reconstruct 8px-based or custom spacing systems with full rules
Responsive Breakpoint Detection
Identify media query breakpoints and folding strategies
Visual Screenshot Assist
Auto-capture top, 35%, and 70% screenshots to help AI understand visual hierarchy
Output
Standardized DESIGN.md Document
Covers Atmosphere → Design System → Component Specs → Replication Guide. AI coding tools read and follow it directly.

FAQ
Frequently Asked Questions
It is a technique that uses artificial intelligence to automatically analyze and extract the design system of any existing website. Unlike AI website builders that create from scratch, it focuses on reverse-engineering colors, typography, spacing, and motion from live webpages into a structured DESIGN.md document.
AI website builders (like Wix AI, Relume) create new sites from scratch. Design Extractor analyzes existing websites' design systems, helping you understand and replicate any webpage's visual style. We are an extractor, not a builder.
Yes. The free plan lets you use your own OpenAI-compatible API Key for unlimited analysis. All design data is processed locally in your browser. Pro ($5/mo) provides platform quota without API Key setup.
We capture CSS variables, font stacks, color palettes, gradients & shadows, motion parameters, component styles, spacing systems, responsive breakpoints, and three visual screenshots to form a complete design system profile.
DESIGN.md is plain Markdown containing standardized design spec descriptions. You can paste it directly into Figma design docs, or let AI tools read it and generate Figma-compatible code.
We combine DOM structure analysis, Computed Styles, and visual screenshot understanding to extract details down to OpenType features, multi-layer shadow parameters, and optical compensation values.
Any publicly accessible HTTPS webpage. Login-required pages, iframe content, or dynamically rendered Canvas may not be fully captured.
Currently Google Chrome and all Chromium-based browsers (Edge, Arc, Brave, etc.). Firefox and Safari versions are in development.
