Buzz

What Buzz is

Buzz is a free desktop application for transcribing and translating audio offline on a personal computer using OpenAI's Whisper. It accepts audio and video files, YouTube links, and live microphone audio. Its features include speech separation, speaker identification, a searchable transcript viewer, keyboard shortcuts, and a watch folder for automatic transcription. Transcripts export as TXT, SRT, or VTT. Buzz supports Whisper, Whisper.cpp, Faster Whisper, and Whisper-compatible models from Hugging Face. After downloading the required models and copying them to an offline computer, it can work without an internet connection. Alternatively, users can set an API key in Preferences to use the OpenAI API for remote speech recognition. A command-line interface supports scripting and automation, and a plugin system includes examples such as AI summaries and transcript resizing. Smaller models run faster but may be less accurate; larger models require more capable hardware or more transcription time. Buzz requires AVX2 CPU support. On macOS it requires Apple silicon; version 1.4.5 was the last version supporting Intel Macs. The Windows app is unsigned and may trigger an installation warning.
