THE TECHNOLOGY: HYBRID AI ENGINE
Most apps simply match pixels. We analyze physics.
Local Signal Processing: Our custom engine runs in background isolates to calculate geometric metrics like Slant Variance, Join Continuity, and Spacing Consistency.
Generative Coaching: We integrate GPT-5-mini to analyze your data and provide empathetic, context-aware tips—telling you how to fix a letter, not just that it's wrong.
Pressure-Sensitive Canvas: Our proprietary 'TraceCanvas' detects pressure and velocity, rendering ink that feels natural and responsive.

Dyslexia-Friendly Aids: Toggle our assistance layer with untimed practice, high-legibility fonts, and spacing guides to reduce difficulty.
