Show GN: EncBird - AI 코치와 쓰는 영어 일기, 쓸수록 똑똑해지는 GenAI 플라이휠

EncBird solves a fundamental problem in language learning apps—users receive feedback they never actually apply. By combining AI coaching, structured journaling, and spaced repetition within a GenAI flywheel that compounds personalization over time, the service ensures active learning. The developer's use of serverless architecture and AI-assisted code generation also demonstrates a blueprint for sustainable, solo-operated AI products.
