Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Real-time voice translation and AI meeting notes platform with bilingual transcription and summaries for multilingual meetings.
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.

Transync AI is a real-time speech translation and meeting assistant platform built for multilingual conversations. It captures spoken audio during meetings and live conversations, transcribes it, and translates between dozens of languages with a dual-screen display that separates the original speech from the translated text. Alongside live translation, the platform records meeting transcripts and generates bilingual meeting notes and summaries, so participants who speak different languages can stay aligned on what was discussed and decided. Transync AI works with common conferencing platforms such as Zoom, Microsoft Teams, and Google Meet, and it offers apps across desktop and mobile as well as a web experience, with the stated goal of not requiring browser plugins. The product positions itself around cross-border business meetings, sales conversations, in-person multilingual discussions, travel, and education involving international participants. It also offers AI voice playback for translated audio. The tool is actively marketed as a live product with downloadable apps and an in-browser web application, targeting teams and individuals who regularly communicate across language barriers in meeting settings. Pricing varies by plan. Check the official website for current pricing.
