Buzz: Offline Audio Transcription Powered by OpenAI Whisper
Complete guide to Buzz - the open-source offline audio transcription app powered by OpenAI Whisper. Transcribe interviews, lectures, and recordings privately on your machine.
What Is Buzz?
Buzz is a powerful open-source desktop application that brings the accuracy of OpenAI's Whisper speech recognition model directly to your computer. Unlike cloud-based transcription services that send your audio data to third-party servers, Buzz runs entirely offline, ensuring your sensitive conversations, interviews, and recordings never leave your machine.
Built with Python and leveraging the latest Whisper model variants including large-v3, Buzz delivers transcription quality that rivals commercial services. It supports batch processing of audio files, real-time microphone recording, and translation from 100+ languages into English.

Offline Transcription
Every transcription happens locally. No internet connection needed after the initial model download. This makes Buzz ideal for sensitive environments like legal offices, medical practices, and journalism.
