Design Extract: How to Clone Any Website's Design With AI

You see a landing page you love. In the old workflow, you'd open DevTools, inspect 50 elements, manually copy hex codes, guess at font sizes, and still get the spacing wrong. Design Extract does this in one command — it reverse engineers any website's visual design into a structured specification that Claude Code or Cursor can reproduce directly.

The Problem It Solves

Describing a design in words is imprecise. "Make it look like Stripe's pricing page" gives Claude Code a vague target that requires 5-10 rounds of visual adjustment. Each round costs tokens and time.

Design Extract eliminates the description problem. It reads the actual CSS, computed styles, keyframe animations, and DOM structure of any page — then packages it into a format AI coding tools can implement directly.

The result: instead of "make it look like this" followed by endless iteration, you get "here are the exact specifications" followed by a close match on the first build.

How to Use It

Install Design Extract from its GitHub repo. Point it at any URL. It outputs a design document containing the color palette with exact hex/RGB values, typography including font families, sizes, weights, and line heights, spacing and layout measurements, animation keyframes and timing functions, interaction patterns like hover states and transitions, and component structure with nesting and hierarchy.

Feed this document to Claude Code or Cursor as context before your build prompt. "Using the attached design spec, build a landing page with the same visual style" produces dramatically more accurate results than any text description.

What It Captures (And What It Doesn't)

Design Extract captures computed CSS — the actual rendered styles, not the source code. This means it gets the final visual output regardless of whether the original was built with Tailwind, CSS modules, vanilla CSS, or a CSS-in-JS library.

It captures animations and transitions including keyframes, durations, easing functions, and trigger conditions. If a button has a hover animation, Design Extract records exactly how it moves, scales, and changes color.

What it doesn't capture: images (it references their positions but doesn't download them), dynamic content loaded via JavaScript after the initial render (though it handles most SPA content), and responsive breakpoints (it captures one viewport at a time — run it at multiple widths for responsive specs).

Practical Workflows

Landing page reproduction. Find 3 landing pages you admire. Run Design Extract on each. Feed all 3 specs to Claude Code with: "Using elements from these 3 design specs, create a landing page for [your product]. Take the color palette from spec 1, the typography from spec 2, and the layout structure from spec 3."

Design system creation. Run Design Extract on your existing site (or a site whose style you want to adopt). The output becomes your DESIGN.md file for Claude Design — giving it brand-consistent context for every future prototype.

Competitive analysis. Extract the designs of your top 3 competitors. Compare their visual approaches side by side. Use the best elements to inform your own design direction — without manually inspecting hundreds of elements.

The Ethics Note

Design Extract captures visual specifications, not proprietary code or copyrighted assets. Using it for inspiration and learning is standard practice — the same as what designers do manually in DevTools every day. Copying a competitor's design pixel-for-pixel and presenting it as original is ethically wrong regardless of the tools you use.
