RoundTable

This project delivered end-to-end platform development and ongoing operational support for RoundTable, an education-focused SNS designed for global Hallyu fans who want to learn Korean through K-pop, K-drama, and K-food content.


Through a strategic partnership with the client, we systematically built core service features—including an AI Tutor system and AI-powered basic Korean speaking practice—so users can learn effectively while forming a global community in one integrated learning space.


We also provide continuous maintenance and technical support to ensure stable operations and uninterrupted learning experiences for users worldwide.

Client Requirements
& Project Direction
Through client interviews and consultations we derived the project's core requirements, and based on those insights we designed it around five areas that needed improvement from user experience and brand perspectives.
1.
Build a global Korean learning platform that leverages Hallyu content (K-pop, dramas, food) as study material
2.
Implement an AI Tutor that analyzes pronunciation, grammar, and speaking in real time to deliver personalized feedback
3.
Provide practical speaking practice through speech-recognition pronunciation correction and scenario-based conversations
4.
Build networking features including follow, peer feedback sharing, and topic-based community boards
5.
Strengthen operational stability and scalability through regular patching, content uploads, and enhanced admin tools
