Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
EvaluAgent is a contact-center quality assurance platform that automatically transcribes, scores, and analyzes customer conversations across calls, chats, emails, and tickets.
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.

EvaluAgent is a UK-based quality assurance and performance-improvement platform built for contact centers, BPOs, QA leads, team managers, and frontline agents. It captures interactions from connected CCaaS, CRM, and helpdesk systems, then transcribes voice calls to text and processes chats, emails, and tickets so every conversation can be reviewed rather than just a manual sample. Its AutoQA engine uses customizable drag-and-drop scorecards to automatically evaluate interactions, applying auto-fail logic and weighting that mirror how a team grades quality. A conversation-intelligence layer adds sentiment analysis, reason-for-contact classification, intent detection, summarization, predictive metrics, and customer-vulnerability signals. Insights flow into coaching plans, performance tracking, and agent feedback. The platform also offers AI-agent observability to detect issues in automated conversations, plus calibration and reporting tools. It integrates with systems such as Genesys, Five9, NICE CXone, Talkdesk, Amazon Connect, Salesforce, and Zendesk, and lists enterprise security credentials including SOC 2 Type II and ISO 27001.
