Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Voice-first AI sales training platform (branded Rory) that runs role-plays, audits real calls, and coaches reps on objection handling and discovery.
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.

SecondBody is a voice-first AI sales training and coaching platform, branded as an AI coach called Rory, that aims to bridge the gap between classroom training and live selling. Reps run simulated cold calls, discovery conversations, and objection-handling scenarios against an AI buyer that pushes back in real time, and the AI scores conversations on dimensions such as talk-to-listen ratio, question quality, objection handling, and methodology adherence. Beyond practice, SecondBody offers conversational intelligence that can audit real sales calls or integrate with call recorders to pinpoint exactly where reps struggle, from weak intros to fumbled objections. It captures top performers' techniques and turns them into reusable playbooks and training material, gives managers analytics on behavioral patterns and skill gaps, and uses gamification such as streaks, leaderboards, and challenges to drive consistent practice. The platform pulls context from CRM data, call recordings, pricing documents, and company resources to keep coaching relevant. It serves SDR and BDR groups as well as enterprise and specialized sales teams, and offers a free tier for solo sellers. Pricing varies by plan. Check the official website for current pricing.
