Tools I Built on the Side

Instead of hand-picking values, you define a structural model. You assign colors and contrast ratios to surfaces, containers, content, and scrims, and Systema computes every resulting token across all modes, conditions, and interaction states automatically.

• Computed Output: Low-level building blocks rather than rigid, high-level prescriptions, giving you full control over a consistent, contrast-aware color system.
• Multi-Agent AI: A built-in AI chat with dedicated personas handles audits, proposals, and hands-on theme editing, so you can refine your system conversationally.
