RemNote is a knowledge-management and learning tool that combines note-taking, PDF and PowerPoint annotation, flashcards, and spaced repetition in one app. Its Lecture Recorder feature captures live audio and produces real-time transcription with timestamped notes, and it also accepts uploaded audio files in MP3, WAV, M4A, AAC, and OGG formats for transcription after the fact. Once a session is recorded, users get a raw transcript of every word spoken alongside AI-organized bullet-point summaries, and can click any sentence to play back the audio at that timestamp, highlight it, or generate flashcards and quizzes. An AI tutor can answer questions by referencing the transcript and citing specific timestamps. RemNote runs as a web app and on desktop, iOS, and Android, with offline access available. It is built primarily for students and serious learners, including medical, law, and language students, who want to capture spoken material such as lectures or meetings and convert it into study-ready notes and review material.
