Turbo AI is an AI note-taking and study platform that records or ingests audio, video, and documents and turns them into transcribed, structured notes, flashcards, quizzes, and AI podcasts.
Buzz is a widely used open-source desktop application that transcribes and translates audio offline on the user's personal computer, powered by OpenAI's Whisper. It is MIT-licensed and actively maintained, with v1.4.4 released in March 2026, and it has grown a large community with roughly 19.7k GitHub stars. Buzz runs on macOS, Windows, and Linux, with installation options including Flatpak, Snap, and PyPI. It supports both importing existing audio and video files and real-time transcription from microphone input, and it can export results in formats such as TXT, SRT, and VTT for subtitling and documentation. The app includes an advanced transcript viewer with search and playback controls, a watch folder for automatically transcribing new files, and a command-line interface for automation. It offers GPU acceleration through CUDA for Nvidia cards, Apple Silicon support, and Vulkan for many other GPUs, which makes faster transcription practical even on laptops. Buzz also provides speaker identification and speech separation for noisy audio, plus a plugin system that adds capabilities like AI-generated summaries. Because all processing happens locally, recordings and transcripts remain on the user's machine rather than being uploaded to a cloud service. Pricing varies by plan. Check the official website for current pricing.

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.
