Most transcription tools quietly route your recordings through someone else's servers and bill per minute. This one inverts that: it wraps OpenAI's Whisper into a desktop app where transcription is a one-time model download, so sensitive audio never leaves the machine and there is no recurring cost after install.
What Sets It Apart
- Multiple Whisper backends (whisper.cpp, faster-whisper) with CUDA, Apple Silicon, and Vulkan acceleration — you can trade speed for accuracy and use whatever GPU you have, not only Nvidia.
- Beyond plain files: YouTube links, real-time microphone transcription with a presentation mode, and a watch folder that auto-processes newly added recordings — it covers live captioning and unattended batch runs, not just one-off uploads.
- Speaker identification and speech separation make it usable on multi-speaker, noisy recordings rather than only clean single-voice audio.
- TXT, SRT, and VTT export plus a CLI drop it straight into subtitle pipelines and scripted automation.
Who It's For
Great fit if you handle sensitive or high-volume audio and want zero cloud exposure or per-minute fees, or you need captioning that works without a network. Look elsewhere if you have no local GPU and want managed cloud-grade speed, or expect a polished mobile app — Buzz is desktop-only (macOS, Windows, Linux), and both accuracy and speed depend on the Whisper model size and hardware you run it on.
