Copy a DESIGN.md into your project, tell your AI agent “build me a page that looks like this,” and generate high-quality UI that stays visually consistent with the design language.
Built with real design depth — including analyzed patterns, tokens, and rules — for high-quality UI generation, not surface-level outputs.
DESIGN.md is a new concept introduced by Google Stitch. A plain-text design system document that AI agents read to generate consistent UI.
It's just a markdown file. No Figma exports, no JSON schemas, no special tooling. Drop it into your project root and any AI coding agent or Google Stitch instantly understands how your UI should look. Markdown is the format LLMs read best, so there's nothing to parse or configure.
| File | Who reads it | What it defines |
|---|---|---|
AGENTS.md | Coding agents | How to build the project |
DESIGN.md | Design agents | How the project should look and feel |
This repo provides ready-to-use DESIGN.md files extracted from real websites.
You can request a DESIGN.md for specific website, including private requests delivered exclusively to you.
You ship products with AI, but every launch still dies quietly because nobody posts about it. EveryFeed plugs your AI assistant into a social workspace that drafts, schedules, and publishes across 35+ channels — no agency, no marketing hire.

Stop building from a blank page. LaunchKit gives your AI coding assistant a complete, working product to start from — websites, startups, and web apps that are clickable on day one.

A Saturday series — DESIGN.md files extracted from the web of the 1990s. Drop one in and tell your AI agent to build a period-accurate vintage UI.
Every file follows the Stitch DESIGN.md format with extended sections:
| # | Section | What it captures |
|---|---|---|
| 1 | Visual Theme & Atmosphere | Mood, density, design philosophy |
| 2 | Color Palette & Roles | Semantic name + hex + functional role |
| 3 | Typography Rules | Font families, full hierarchy table |
| 4 | Component Stylings | Buttons, cards, inputs, navigation with states |
| 5 | Layout Principles | Spacing scale, grid, whitespace philosophy |
| 6 | Depth & Elevation | Shadow system, surface hierarchy |
| 7 | Do's and Don'ts | Design guardrails and anti-patterns |
| 8 | Responsive Behavior | Breakpoints, touch targets, collapsing strategy |
| 9 | Agent Prompt Guide | Quick color reference, ready-to-use prompts |
Each site includes:
| File | Purpose |
|---|---|
DESIGN.md | The design system (what agents read) |
preview.html | Visual catalog showing color swatches, type scale, buttons, cards |
preview-dark.html | Same catalog with dark surfaces |
