PROJECT DOCUMENTATION & NOTES

Concept & Overview

Tsumugi is a native iOS language-learning application designed for beginners to master grade-level Japanese through interactive tactile tracing, radical breakdown puzzles, and AI-powered conversational practice. The app bridges classical linguistic pedagogy with spatial computing and local neural intelligence.

Technical & Architecture Highlights

  • Spatial Plane Tracing: Utilizes RealityKit and ARKit plane raycasting to enable spatial kanji stroke tracing in physical environments, providing real-time feedback on stroke order and precision.
  • On-Device Conversational AI: Integrates MLX Swift on-device neural models for low-latency dialogue practice and context-aware grammar correction without sending sensitive audio data off-device.
  • Spaced-Repetition Memory Engine: Employs SwiftData for local persistence, managing spaced-repetition study queues paired with synchronized Ruby furigana typography annotations.
