NoteMate is a web based application that converts lecture recordings into structured, review ready notes. It uses artificial intelligence to transcribe audio, generate summaries, and produce supplementary study materials such as flashcards and quizzes. The platform is designed for students who want to focus on understanding lecture content rather than manually taking notes during class. The core workflow involves recording a lecture, either live or from an existing audio file, and then selecting a desired output format. Available formats include lecture notes, summary modes, flashcards, and quizzes. Flashcards incorporate a spaced repetition system where users can mark cards as "Got it" or "Needs work," and each card retains a timestamp linking back to the original audio. Quizzes provide explanations for each answer option, including the incorrect ones, so that wrong answers become learning opportunities rather than simple marks. The service also sends reminders to help maintain a revision schedule. NoteMate offers a free tier that includes 180 minutes of transcription per month, one flashcard set and one quiz per month, recordings up to two hours in length, lecture and notes summary modes, and text export. The premium tier provides unlimited minutes subject to fair use of up to one hundred hours per month, access to all six summary modes, recordings up to three hours in length, and integration with Google Drive and Notion for export. The application was built by a student and is intended to support active learning by reducing the time spent on note organization while preserving the accuracy of lecture content.
