Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI roleplay and coaching platform for regulated industries where reps rehearse customer conversations with AI avatars.
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.

SmartWinnr is a practice-first AI roleplay and coaching platform aimed at sales teams in regulated industries such as pharmaceuticals, medical devices, and other life sciences fields. Reps rehearse real customer conversations through voice-based, two-way simulations with AI avatars that listen, ask follow-up questions, raise objections, and react to delivery, helping build compliant messaging into habit. After each session, the platform provides automated, multi-dimensional scoring and real-time AI coaching that highlights conversation quality, which the company says reduces manager workload by handling much of the evaluation. Buyer personas can be customized to mirror ideal customer profiles across industries, and the company states that new lifelike simulations can be created or updated quickly from customizable templates. Managers and enablement leaders get analytics dashboards that show rep scores, practice frequency, and skill gaps so they can target coaching efficiently, while gamification features such as points, badges, and leaderboards encourage ongoing practice. SmartWinnr is accessible on desktop and mobile and is designed for sales leaders, training managers, and enablement professionals who need scalable, audit-conscious practice for customer-facing teams. Pricing varies by plan. Check the official website for current pricing.
