우리가 벼락치기만 하게 되는 이유는 간단합니다. 그날 배운 건 그날 바로 복습하는 게 가장 좋지만, 공부할 내용은 매주 새롭게 쌓입니다. 따로 공부할 시간은 없고, 무엇보다 너무나 귀찮아서 미루게 됩니다. 결국 우리는 항상 벼락치기를 하고, 다음 번엔 미리미리 공부하겠다고 다짐하죠. 하지만 그것은 항상 다짐으로 끝나고, 습관으로 이어지지 못합니다. 공부할 게 너무나 많은 학생들이 별도로 시간을 많이 쓰지 않고도, 의식적으로 공부할 노력을 들이지 않고도 언제 어디서든 누구나 공부한 내용을 쉽게 복습할 수 있도록 만든 앱이 바로 문득입니다. 문득은 강의자료 PDF나 사진과 같은 정리한 학습 내용을 바탕으로 자동으로 AI 퀴즈를 생성하고 그것을 잠금화면에서 풀게 하는 앱으로, 평소 책 펼 힘도 없이 휴대폰만 보게 되는 날에도 누구나 공부가 되게 하는 — 기존에 없던 학습 방식을 제공합니다. 한 바퀴를 다 풀면 학습 리포트로 내가 어느 개념이 약한지 분석해주고, 약점 보완 맞춤형 퀴즈 생성까지 도와줍니다. ■ 카드를 만들지 않아도 되니까 PDF·PPTX 파일, 사진, 노션 페이지만 연결하세요. 문제, 보기, 정답까지 AI가 자동으로 만들어 드려요. 카드 만드는 시간 0분, 공부는 바로 시작. ■ 앱을 열지 않아도 복습되니까 잠금화면에 복습 카드가 나타나요. 화면을 켤 때마다 한 문제씩 — 하루에도 수십 번 생기는 자투리 순간이 전부 공부 시간이 됩니다. ■ 약점 위주로 다시 보완해주니까 회독마다 학습 리포트로 개념별 약점과 강점을 짚어주고, 약한 부분 위주로 퀴즈를 다시 만들어 드려요.
