How it works
Seven steps, one friendly learning rhythm.
NihonGoAIR supports young children, school students, teens, and adults with the same learning engine and adaptive UI density. Explore the core learning loop.
Choose Learner Mode
Select between Young Child, School Student, or Teen/Adult mode. The app adapts its UI density, navigation, and learning style to perfectly match the user, while keeping the same powerful core engine.
- Adapts navigation density and labels based on age
- Young child mode simplifies navigation (audio & pictures first)
- Adult mode provides full SRS detail and JLPT tracks
Discover in AR
Point your phone at everyday objects. Using real-time object detection and LiDAR depth mapping, NihonGoAIR instantly displays floating, readable labels (Kanji, Kana, Romaji, and English) right in your real environment.
- Real-time object detection using YOLOv8n CoreML model
- LiDAR depth scoring for precise spatial text placement
- Three-line readability hierarchy for Kanji, Kana/Romaji, and English
