AI coaching platform for in-person and field sales that records, transcribes, and analyzes face-to-face conversations via a mobile app.
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.

Siro is an AI coaching and conversation intelligence platform designed specifically for in-person and field sales teams, a segment that traditional call-recording tools built for video meetings do not cover. Reps record their face-to-face customer conversations using Siro's mobile app, and the platform automatically transcribes and analyzes those recordings to surface coaching opportunities, objections, and selling behaviors. A real-time capability called Halftime delivers coaching cues mid-conversation. Siro includes Ask Siro, which lets sales leaders query recorded field conversations in natural language to find patterns in objections, competitive mentions, and rep performance, with answers linked back to specific recordings so managers can review and coach efficiently across many consultations. A self-coaching feature surfaces how stronger reps handled similar situations, giving reps an example to learn from. The platform also drafts follow-ups, flags key deal moments, and syncs data to CRM systems. Siro serves industries with heavy field and in-home selling, such as home improvement, home services, automotive retail, telecom, multifamily housing, and medical aesthetics. Pricing varies by plan. Check the official website for current pricing.
