• Matches your brand by pulling colors and fonts from your website
• Redraws existing draw.io, Mermaid, or Excalidraw diagrams in a cleaner style
• Sizes diagrams for docs, slides, social posts, or print
• Exports to PNG or SVG when you ask

Color System

• Generates full tonal scales (light to dark) for your brand colors
• Creates semantic color sets for success, warning, error, and info states
• Tests all color combinations for accessibility compliance (WCAG AA/AAA)
• Builds matching dark mode and light mode palettes
• Provides usage guidance for each color in your system
