Any website's design system, in one click.
GleanUI reads the page you're on and turns it into a design spec: colors with roles, fonts with licenses and free look-alikes, spacing, components with their states, the page blueprint and motion. Then it hands all of it to your AI, or to Figma.
The Chrome Web Store listing is in review. Pro keys work the moment it is live, and on the Firefox build.
What a capture contains
Everything is measured from the real page: computed styles, stylesheets, fonts, images and screenshots. Nothing is guessed.
Colors
Palette with semantic roles, tonal scales, contrast pairs and the alternate theme. Brand color first.
Typography
Every family in use, identified against Google Fonts, Fontshare and foundry catalogs. Free, paid or system, with free look-alikes for paid fonts.
Spacing, radius, shadows
The grid, the radius scale and the elevation vocabulary as tokens, ready for Tailwind, DTCG or Figma variables.
Components
Buttons, inputs, cards and more as variants with hover, focus and active states, padding, icons and real screenshots.
Page blueprint
Section by section: what each one is, its geometry, its copy and its screenshot, so an AI can rebuild the layout.
Motion and icons
Keyframes, transitions and the libraries driving them. Icons matched by shape to Lucide, Heroicons, Phosphor and nine more sets.
Send it anywhere
One click opens the AI you use and drops in the prompt, the spec and the screenshot. Or export.

Questions
Does it upload the pages I capture?
No. Captures live in your browser. Data leaves it only when you send a capture to an AI, create a share link, or use hosted AI. See the privacy policy.
Do I need an API key?
On Free, yes: add your Anthropic, OpenAI, Google or OpenRouter key and requests go straight to them. Paid plans include hosted AI with no key.
How does the Figma plugin get my capture?
With a paid plan, choose Send to → Figma in the extension and press Import in the plugin. It works in the Figma desktop app. The free tier copies a payload you paste.
What is the MCP server for?
It lets Claude Code, Cursor, Codex and Windsurf read your captures, get replication prompts and verify their rebuild against the original.
