Extension Metadata

Screenshots
About this extension
Extract the design system and theme of any live website in one scan. Not a list of hex codes. The actual look: theme, color pairings, typography, spacing, corners, depth, gradients, glass, and imagery, read straight from the rendered page.

Open the side panel on any site. Click Scan This Page. You get a design system you can hand to a designer, a developer, or an AI coding agent.

WHAT YOU GET

Aesthetic profile
The read most tools skip. Light or dark. Dense or airy. Sharp or rounded. Flat or layered. High or low contrast. Plus the brand color that carries the page.

Color pairings, not a color list
Which background goes with which text and which border, per surface. Assigned by how much area each pairing actually covers, so the palette reflects the page instead of a frequency count.

Typography
Font families, size scale, weights, line heights, and the @font-face sources. Licensed fonts get a fallback stack and a note telling you to supply the file.

Effects and imagery
Gradients, glassmorphism, background media, shadows, and border radius. The parts that make a site feel like itself.

Assets
Logos, SVGs, and images used on the page, browsable and downloadable.

Element picker
Hover any element, click, and scan just that subtree.

THREE EXPORTS

JSON. Structured tokens for your build.
Markdown. Written for LLMs. Paste into Claude Code, Cursor, Codex, Copilot, or Windsurf and your generated UI stops guessing at colors.
HTML style sheet. A visual design system page with annotated, coded components you can open, read, and share.

WHY IT'S DIFFERENT

Most extractors dump every color and font they find and call it a design system. You get 40 grays and no idea which one is the border. This one records which values go together, how much of the page each covers, and how confident it is in every token. CSS-variable-backed values are marked high confidence. Close calls are flagged for a glance.

WHO IT'S FOR

Developers rebuilding a reference site's look
Designers auditing brand consistency across pages
Product managers writing a brief that doesn't need a designer to decode
Anyone feeding design context to an AI coding agent

PRIVACY AND PRICING

Free. No account. No scan limits. No upgrade tier.
Every scan runs client-side in your browser. Nothing is uploaded. No servers, no analytics, no tracking.
