Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Convin when coaching agents with real-time cues and post-call scoring 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 conversation intelligence platform for contact centers and sales teams that records, transcribes, and scores calls, chats, and emails.
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.

Convin is an AI-backed conversation intelligence platform built primarily for contact centers and sales teams that handle high volumes of customer interactions. Its core function is to capture and analyze the full range of conversations, recording calls and ingesting chats and emails, then generating transcriptions and concise summaries for each interaction. On top of that data, Convin's AI analyzes conversations to detect buying signals, objections, competitor mentions, sentiment shifts, and recurring pain points, and it builds searchable conversation libraries. The platform applies automated call scoring for quality, sentiment, and compliance, which replaces sampling-based manual QA by evaluating interactions at scale rather than a small subset. Convin also offers real-time coaching cues and agent assistance during live calls, along with role-based dashboards for agents, managers, and leaders so each can see relevant performance data. It integrates with CRM systems to capture action items and next steps for follow-up. Convin serves regulated and high-volume industries such as fintech, banking, healthcare, real estate, and retail, and is aimed at teams that want data-driven coaching and quality assurance rather than subjective spot checks. Pricing varies by plan. Check the official website for current pricing.
