AI Character Japanese Language Learning Platform
Learn Japanese through natural conversation with AI characters in a gamified experience
Challenge
Traditional Japanese language learning tends to be monotonous, with sustained motivation being a challenge. Practical conversation practice opportunities were limited, leading to the problem of having knowledge but being unable to speak.
Solution
Introduced mission-based gamification for learning JLPT N5→N1 through a story format. Achieved real-time voice dialogue using GPT-4o and Whisper API, and immersive conversations with anime-style characters via Live2D.
