This project was a design-led development initiative where we took full ownership of UI/UX design and production for an app/web service that helps foreigners learning Korean study modern Korean slang in a structured way.

Because traditional Korean learning materials often fail to cover fast-changing modern slang, foreign learners have struggled to understand the latest expressions used by native speakers. The project required a high-quality user interface for a slang-focused learning platform, including intuitive UI to present definitions, example sentences, origins, and similar expressions, as well as user-friendly interfaces for personalized search and recommendation features.

Key design principles included visual-first UI/UX to minimize language barriers for foreign users, a flexible interface structure that can support future multilingual expansion, and a continuous improvement process based on feedback from actual foreign test users. The goal was to create an environment where learners can participate actively and enjoy the learning experience.
