What problem does it solve? Choosing consistent styles, color palettes, typography, and UX patterns for a new web or mobile interface is slow and error-prone, and generic advice often ignores the target stack or product type. ## Core Features & Use Cases - Design System Generation: Runs a multi-domain search across product types, styles, colors, landing patterns, and typography to produce a complete design system with reasoning rules, anti-patterns, and a pre-delivery checklist. - Searchable Design Database: Provides BM25-based search over 84 styles, 192 color palettes, 74 font pairings, 98 UX guidelines, 104 icons, 16 GSAP motion presets, and 25 chart types across 22 technology stacks. - Persistence & Tuning Dials: Saves design systems as a MASTER.md plus per-page overrides, and tunes output with variance, motion, and density sliders. - Use Case: When building a fitness dashboard in Next.js, generate a full design system with palette, fonts, and motion presets, then query stack-specific guidelines before implementing components. ## Quick Start Ask the AI to generate a design system for your product type and stack, for example: design a modern minimal UI for my fitness tracking web app.
