Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI-powered parallel and power dialer for sales teams with automatic call recording, real-time assist, AI scoring, and roleplay coaching.
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.

Orum is an AI-powered sales dialer platform built for sales development teams that make high volumes of outbound calls. Its core function is to maximize live conversations through power and parallel dialing, calling multiple numbers at once and connecting reps only when a real person answers, while routing past voicemails and busy signals so reps stay in back-to-back conversations. Around the dialer, Orum layers AI features for recording, coaching, and analysis. Every call is automatically logged and recorded, with timestamps that make it easy to revisit specific moments, and Orum integrates with conversation intelligence tools so recordings flow into a team's existing stack. Its Assist feature listens to conversations in real time and surfaces the right response when a rep needs it, such as handling an objection, responding to a competitor mention, or recognizing a buying signal. Orum also offers an AI coaching suite with automatic call scoring against proven criteria, scenario-based AI roleplay practice, and coaching portals that build each rep's coaching playlist from performance trends. Orum is aimed at SDR and outbound sales teams that want to combine high-efficiency dialing with AI-driven coaching. Pricing varies by plan. Check the official website for current pricing.
