Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and PowerDialer.ai when sales managers reviewing recorded and transcribed calls to coach reps matters most. Run both through a week of actual calls to see which suits your workflow.
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 outbound sales teams that auto-records, transcribes, and analyzes calls and surfaces AI coaching suggestions.
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.

PowerDialer.ai is an AI-powered outbound calling platform aimed at small and mid-sized B2B sales teams, call centers, and high-volume prospecting groups. Its core is a dialer that supports multiple modes, including power dialing for sequential calls, parallel dialing that places several simultaneous calls and connects a rep to the first prospect who answers, and predictive dialing, alongside ringless and AI-personalized voicemail with voice-cloning capabilities. Layered on top of the dialer is a set of AI features relevant to revenue intelligence: calls are automatically recorded, transcribed in real time, and analyzed to identify winning talk tracks, with AI-generated summaries of conversations and instant coaching suggestions for reps. The platform also includes performance analytics and dashboards that track calls, connects, and meetings, identify high-converting personas, and surface optimal calling times. It integrates with CRM systems to log activity and keep records in sync, and it is marketed with flat-rate pricing that avoids per-seat penalties. The product positions itself as an affordable alternative to higher-priced parallel dialers, targeting teams that want fast setup, conversation recording, and AI coaching without enterprise complexity.
