About

I started PrintableHandwriting because my own handwriting was terrible. After searching for tools to improve it, I found most resources were blurry templates that didn't adapt to individual needs. So I built something better.

The platform combines algorithmically-generated worksheets with AI-powered handwriting analysis. The analysis system evaluates five dimensions — legibility, consistency, fluency, structure, and pen control — to generate personalized improvement plans.

Every feature is built with the same engineering discipline I apply to software: measurable inputs, testable outputs, and continuous iteration based on real user feedback.
