Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI note-taking app that transcribes meetings and lectures into minutes, summaries, and study materials.
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.

NoteLyn AI is an AI note-taking application that captures meetings, lectures, and other audio and turns them into structured notes, meeting minutes, and study materials. For meetings, it records audio with speaker diarization, or accepts uploaded files and links to recorded Zoom, Teams, and Google Meet sessions, then produces a timestamped transcript with speaker labels alongside a structured summary that highlights decisions, open questions, main topics, and action items with owners and due dates. It frames meeting output around an explicit decision log so that conclusions and follow-ups remain traceable over time. Beyond meetings, NoteLyn doubles as a learning tool, converting audio, PDFs, links, images, and videos into clear notes and generating flashcards, quizzes, and AI question-and-answer for spaced-repetition study. This dual focus makes it suitable for both professionals documenting client calls, standups, and project reviews and students working through lectures and research. NoteLyn supports multiple languages and is available on iOS, Android, and the web, with note export and sharing options. Pricing varies by plan. Check the official website for current pricing.
