과백이 - AI 문제생성·약점분석

Gwabaek-i is an AI learning partner that facilitates concept organization, customized problem generation, solution grading, and weakness analysis simply by uploading lecture materials.

When the exam scope is extensive or you have a large stack of lecture PDFs, you can go beyond simply rereading the materials and organize the problems to actually solve and key points to review all at once.

Key Features
