    description
    LecTranscribe는 강의 영상을 텍스트로 변환하고 AI로 분석해주는 Chrome 확장 프로그램입니다.
    
    주요 기능:
    - YouTube 영상 전사: 영상 페이지에 뜨는 플로팅 pill에서 배속·프로젝트 설정 후 확장 아이콘 클릭 한 번으로 자동 녹음·전사
    - LMS 강의 전사: 대학교 LMS(e-Campus 등)에서 강의 영상 URL 자동 감지, 원클릭 전사
    - 실시간 녹음 상태 표시: 남은 시간 카운트다운과 진행 바를 영상 위에 표시
    - YouTube 음소거 감지: 녹음 전 플레이어 음소거 상태를 감지하고 사용자에게 안내 (자동 해제 없음)
    - 배속 녹음: 1x / 2x / 4x 중 선택해서 대기 시간 단축
    - 타임스탬프 포함: 전사 결과에 정확한 타임스탬프가 함께 제공됩니다
    - 주제별 섹션 자동 분할: AI가 긴 강의를 주제별로 나눠주고 섹션마다 요약해줍니다
    - AI Agent 질의응답: 전사 내용에 대해 자유롭게 질문하고 노트·시험 대비 문제도 자동 생성
    - 프로젝트 관리: 과목별로 전사 기록을 정리할 수 있습니다
    
    사용 방법:
    1. YouTube: 영상 페이지에 나타나는 LecTranscribe pill의 ⚙ 아이콘에서 배속/프로젝트 설정 → 우측 상단 확장 아이콘 클릭 → 자동 녹음 시작
    2. LMS: 강의 영상 재생 시 자동 감지, 화면 우측 하단 LecTranscribe 버튼 클릭(고려대학교 학생 전용입니다)
    3. 전사 완료 후 lectranscribe.vercel.app 대시보드에서 결과 확인, 타임스탬프 클릭으로 영상 해당 위치로 이동
