The Design Index
A searchable database of brand design systems, made machine-readable so AI agents can build products that match a brand's look and feel.
Overview
The Design Index is a database of 700+ brand design systems, made machine-readable for AI agents. Ask an AI to 'build something that looks like Stripe' or 'use Apple's design language,' and it has structured references to work from: extracted typography scales, color palettes, component signatures, and AI-generated notes on each brand's aesthetic. Comments left on each brand page feed back in to improve the documentation over time.
