Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and PitchMonster when ramping new reps with structured role-play scenarios matters most. Run both through a week of actual calls to see which suits your workflow.

AI sales role-play training platform where reps practice cold calls, discovery, and demos against AI buyer personas and get scored feedback.
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.

PitchMonster is an AI-powered sales role-play training platform that lets reps rehearse real conversations before meeting actual customers. Teams build simulations tailored to their specific buyer personas, objections, and talk tracks, and reps practice scenarios including cold calls, discovery meetings, product demos, and objection-handling drills. After each role-play, the AI provides feedback analyzing speech patterns, vocabulary, sentiment, filler words, sentence structure, and pacing, and produces scorecards measured against a team's own coaching standards. It ships with a library of ready-to-use scenario templates and adds gamification through leaderboards and challenges to encourage consistent practice. Sales leaders, enablement teams, and hiring managers use it to standardize messaging, accelerate ramp, and screen candidates, and it is adopted by mid-market and enterprise organizations with documented customers including Lenovo and Xfinity. PitchMonster focuses on the skill-building, pre-call side of the sales workflow, giving SDR and AE teams a safe space to improve before live conversations, and complements conversation-intelligence tools that analyze real recorded calls. Pricing varies by plan. Check the official website for current pricing.
