Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
AI conversation intelligence and revenue platform that records and summarizes sales calls and automates CRM updates and post-call workflows.
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.

Momentum is an AI conversation intelligence and revenue orchestration platform that records, transcribes and analyzes sales and customer-success calls to turn unstructured conversations into structured, actionable data. After calls, it generates AI summaries and notes and extracts key signals, then uses agent-style automations to handle downstream work such as updating Salesforce fields, advancing pipeline stages and generating call notes so reps spend less time on manual data entry. The platform is organized around purpose-built agents, including a deal execution agent for post-call CRM updates, a customer retention agent that surfaces churn signals and sentiment from conversations, a revenue-leadership agent that produces executive briefings and pipeline insights, and a coaching agent that offers call-based coaching recommendations. Momentum integrates deeply with Salesforce, connects to Slack for real-time deal notifications and deal rooms, and can sync data into warehouses such as Snowflake for analysis. It also offers botless recording for Google Meet, capturing calls without adding a visible participant. Momentum is aimed at sales representatives, customer success managers, sales managers, RevOps teams and revenue leaders who want conversation data to flow automatically into their CRM and reporting. Pricing varies by plan. Check the official website for current pricing.
