There are free DESIGN.md templates everywhere, but they make everything look like everyone else. Design DNA is built from your taste, not a template, so your projects stay recognizably yours no matter which AI builds them.
Ask any model to build a page and you get the same starter pack: Inter, a purple gradient, three identical rounded cards, a pill button. Not because it is bad, but because it is the average of everything it has seen. Without a point of view of your own, every build drifts back to that average and reads as generated.
Design DNA walks you through your look by clicking, not by knowing design vocabulary. At the end you get a DESIGN.md: your fonts, colors, spacing, shape, and motion, plus the reasoning behind them. Drop it into any project and your agent builds to your identity instead of the default one. Change it in one place and everything you make stays in step.
Pick from real, rendered options for type, color, shape, and more. Type your own words to test a font. Hit Surprise Me and let it explore for you.
Machine-readable tokens plus plain-language do's and don'ts.
Any coding agent reads it and stays on-brand.
