Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Sybill when drafting post-meeting follow-up emails for reps matters most. Try them side by side on real calls before deciding — needs vary by team.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI sales assistant that records and transcribes meetings, writes summaries and follow-up emails, and updates the CRM across Zoom, Google Meet, Teams, and Webex.
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.
