Title: Steal Website Styles for Free: Turn Any UI into an AI-Ready Design Doc
Intro
You know that feeling when you see a website with perfect spacing, a killer color palette, or a component layout that just clicks? You want to capture it, but you don't want to screenshot it or manually copy-paste CSS values for 20 minutes.
I ran into a project that solves this in a clever way. It’s a Chrome extension that looks at a webpage, extracts the design tokens (colors, fonts, spacing), and formats everything into a clean Markdown document. The best part? That output is structured specifically so you can feed it directly into an AI tool like ChatGPT or Claude for reference.
What It Does
The tool is called design-md-chrome. Once installed, you click the extension icon on any live website. It scans the computed styles of the visible DOM, pulls out the key design decisions (primary colors, font stacks, border radii, grid gaps), and assembles them into a readable design.md file.
You can copy the result to your clipboard or download it. The output is not a screenshot; it's a structured text document that describes the visual system of the page.
Why It’s Cool
This isn't just a “CSS inspector lite.” The real value here is the portability and the AI-readiness.
-
Structured for AI: The output is formatted in a way that large language models can easily parse. You can prompt a model with this text and say “recreate this style for my React app” or “generate a Tailwind config based on this.”
-
No Login, No API: It’s just a browser extension. You aren't sending your data to a server. Everything happens locally in your browser.
-
Inspiration to Implementation: You see a design pattern you like? One click, and you have a portable design spec. It lowers the barrier between “that looks nice” and “I can use that in my next PR.”
How to Try It
The repo is straightforward.
- Clone it:
git clone https://github.com/bergside/design-md-chrome - Load it in Chrome: Go to
chrome://extensions, enable “Developer mode”, click “Load unpacked”, and select the folder. - Use it: Navigate to any website (try your favorite SaaS landing page). Click the extension icon. A side panel will appear with your beautiful new design document.
You can also check the README in the repo for specific installation notes. It’s a standard Chrome extension setup.
Final Thoughts
This is a niche tool, but the niche is real. If you do frontend work, design systems, or even just need to quickly document a style for a hackathon project, this saves you significant time. It’s not a replacement for a design tool, but it’s a perfect bridge between “I saw this online” and “I’m building it now.”
Worth adding to your dev toolkit.
