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.
Best suited for
DialDesk is an Indian customer-experience company that pairs managed contact-center operations with an AI software layer called CallMaster, available either bundled with its managed service or as standalone SaaS for businesses running their own agents. Its conversation-intelligence engine records and transcribes interactions in real time across voice calls, live chat, and WhatsApp, processing voice tone, speech pacing, and language patterns to create structured records as conversations happen. Using NLP, speech analytics, and sentiment analysis, the platform automatically scores 100% of interactions against customizable QA rubrics covering script adherence, empathy, product accuracy, mandatory disclosures, resolution quality, and compliance, returning scores within seconds of a call ending. Real-time dashboards surface customer frustration, churn signals, and compliance risks for supervisors, while auto call summarization logs notes back to the CRM. It is aimed at startups, SMBs, and growth-stage enterprises in sectors like e-commerce, BFSI, healthcare, and SaaS that want automated quality monitoring and agent coaching across every customer conversation rather than manual sampling.
