Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Second Nature when certifying reps on new messaging before a product launch matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

AI role-play sales training software where reps practice live conversations with a conversational AI buyer and receive scoring and 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.

Second Nature is an AI role-play platform that lets customer-facing teams rehearse sales conversations by talking to a conversational AI that responds in real time, rather than reading scripts or scheduling peer practice. Reps can drill pitches, discovery questions, and objection handling as often as they like until they reach fluency and confidence, with the AI providing scoring and structured reports against the behaviors a team cares about. A core selling point is fast content creation: the platform can generate realistic role-play simulations from existing sales material in minutes, and it supports many languages and conversation styles for global organizations. It integrates with CRMs including Salesforce and HubSpot so enablement leaders can tie practice to live workflows. Typical applications include shortening new-hire ramp time, certifying reps on new messaging ahead of product launches, and giving managers analytics on where individuals and teams struggle. Second Nature focuses squarely on the practice-and-coaching side of the sales-conversation lifecycle, complementing call-recording tools rather than replacing them, and is used by enterprise and mid-market sales organizations. Pricing varies by plan. Check the official website for current pricing.
