Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and CloudTalk when quality-assurance scoring of support calls at scale matters most. Try them side by side on real calls before deciding — needs vary by team.
Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
CloudTalk is a cloud call-center platform that automatically transcribes calls and adds AI summaries, sentiment analysis, and conversation intelligence for sales and support teams.
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.

CloudTalk is a cloud-based business calling and call-center platform that pairs voice infrastructure with an AI Conversation Intelligence layer for sales, support, and operations teams. On top of its phone system (international numbers, IVR, call routing, recording, dialers, SMS, and WhatsApp), CloudTalk automatically converts recorded calls into multilingual transcripts and stores them in a searchable interaction database. Its AI then generates instant call summaries and smart notes, applies automatic tags, extracts the key topics discussed, and scores calls against custom criteria. Sentiment analysis interprets the mood of each speaker segment by segment, classifying calls as positive, neutral, or negative, while talk/listen ratio tracking surfaces coaching opportunities across agents. Summaries and notes can sync into CRMs such as Salesforce, HubSpot, and Pipedrive through CloudTalk's broad integration catalog. Conversation Intelligence is available as a paid add-on across CloudTalk's calling plans. It is aimed at teams that handle high call volumes and want to review, analyze, and coach on conversations at scale rather than manually.
