Balto is a contact-center AI platform centered on real-time guidance during live customer and sales calls. Rather than focusing on post-call review, Balto listens to conversations as they happen and surfaces dynamic prompts, objection-handling cues, compliance checklists, and knowledge-base answers to the agent in the moment. Its Agent Assist pulls relevant information so reps can respond to customer questions instantly, while real-time QA automatically scores interactions across all calls and flags compliance risk early, maintaining an audit trail for supervisors. Coaching automation tailors recommendations to each agent's performance, and real-time note generation produces call summaries without manual write-ups. Balto also offers voice AI agents to handle high-volume, repeatable calls and supports omnichannel context across voice and digital channels. It integrates with CRMs and telephony systems such as Salesforce and RingCentral. The platform is used across industries including healthcare, insurance, banking, collections, and home improvement, and is aimed at contact centers and sales teams that want in-the-moment guidance, compliance assurance, and automated quality management at scale. Pricing varies by plan. Check the official website for current pricing.

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.
