Turbo AI, formerly TurboLearn AI, is an AI-powered note-taking and study workspace that converts spoken and written content into organized, editable study materials. Users can record lectures, meetings, or brainstorming sessions live in the app, or upload PDFs, videos, and audio files (common formats such as MP3, WAV, M4A and others). The platform transcribes the audio, applies speaker diarization to identify who is speaking, and adds timestamps and key-concept highlights, then generates structured notes. From those notes it can produce flashcards, quizzes, practice tests, and AI-generated audio podcast summaries. A Google Docs-style editor supports collaborative, real-time editing alongside an AI teammate that can refine, comment on, and reorganize notes, including handling math formulas, chemical equations, and code. Turbo AI is available on the web and on iOS and Android, with a desktop app announced as coming soon, and notes sync across devices. It is aimed primarily at students, educators, and professionals who want to capture lectures and meetings and convert them into reviewable knowledge. The company reports more than 5 million users.
