Open-source Rev alternatives

Meetily is an open-source AI meeting assistant that records, transcribes and condenses meetings entirely on your local machine, so audio and notes never leave your infrastructure. It is aimed at professionals and enterprises that need meeting intelligence without giving up privacy, compliance or control.

Transcription runs locally using Whisper or Parakeet models, and summaries are generated through Ollama with open-source language models, which avoids paying for external APIs. It works offline and supports multiple meeting platforms. The project mentions speaker diarization, and the desktop app is built with Rust for macOS and Windows. Because it is open source, you can self-host and modify it for your own needs.

The community edition is MIT licensed. A paid Meetily PRO tier is offered for users who want better accuracy, richer export options, customizable summary workflows and team features. It suits people who sit in many calls and want searchable notes without sending recordings to a third-party cloud.

Buzz is a desktop application that turns recorded speech into text and translates it, all on the user's own computer. It builds on OpenAI's Whisper speech recognition models, so audio files do not have to be uploaded to a third-party transcription service. The project is written in Python and released under the MIT license.

The app is distributed for Windows, macOS and Linux. Windows users get an installer, Linux users can choose Flatpak, Snap or AppImage packages, and a PyPI package exists for people who prefer a pip-based setup with ffmpeg installed. Nvidia GPU acceleration through CUDA is supported for faster transcription, and recent releases require Apple silicon on Macs.

Because processing happens locally, Buzz suits people who handle sensitive recordings or want to avoid per-minute fees from cloud transcription services. It runs as a local program rather than a hosted service, so there is no account to create.
