Popular open-source desktop app that transcribes and translates audio offline on your own computer using OpenAI's Whisper.
Salesforce-native revenue platform unifying conversation intelligence, sales engagement, a dialer, and real-time coaching.
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.

Revenue.io is a Salesforce-native revenue execution platform that combines conversation intelligence, sales engagement, a sales dialer, and real-time guidance in a single system. For meetings and calls, the platform automatically records and transcribes conversations, then applies AI analysis to surface topics, objections, competitor mentions, and next steps, writing results back to CRM records so reps avoid manual data entry. A real-time coaching capability surfaces guidance and prompts to reps during live calls rather than only after the fact, helping them handle objections and follow approved messaging. A mobile capability lets field reps capture in-person meetings, generate transcripts and summaries, and sync insights to Salesforce. Because it is built natively on Salesforce, activity, calls, emails, and meetings are logged directly in the CRM, and managers can use call libraries, scoring, and analytics for coaching across the team. Revenue.io is aimed primarily at mid-market and enterprise Salesforce-based sales, revenue operations, and enablement teams that want to consolidate several point tools into one platform. Pricing varies by plan. Check the official website for current pricing.
