AI platform for transcription, subtitles, dubbing, and live captioning across many languages.
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.

Maestra is an AI-powered media platform that provides transcription, subtitling, translation, and dubbing for audio and video content, both on demand and in real time. For transcription, users upload audio or video and Maestra produces speech-to-text output with features such as speaker detection, punctuation, and timestamps. The platform can auto-generate subtitles and captions, which users can edit, style, and export in multiple formats, and it can translate that text across a large set of languages. Maestra also offers live transcription for meetings, webinars, and streams, with stated integrations for platforms including Zoom and Microsoft Teams, as well as live production tools. This makes it usable both as a post-production transcription and captioning service and as a real-time captioning layer over live sessions. Maestra is aimed at media companies, content creators, marketers, and organizations that need multilingual transcripts, subtitles, and captions, and that may also want real-time captioning for live events and meetings. Pricing varies by plan. Check the official website for current pricing.
