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.

OpenTranscribe is a self-hosted, containerized web application for transcribing and analyzing audio and video files using current AI models. It is built with a FastAPI backend, a Svelte/TypeScript progressive web app frontend, and a Docker-based stack that includes PostgreSQL, Redis/Celery task queues, MinIO object storage, and OpenSearch for full-text indexing. Transcription is handled by WhisperX with the large-v3-turbo model and Faster-Whisper, supporting more than 100 languages, while automatic speaker diarization uses PyAnnote v4 with overlap detection. The project is licensed under AGPL-3.0 and is actively maintained, with v0.4.1 released in April 2026. Beyond transcription, OpenTranscribe provides AI-powered summarization (including BLUF-format and custom JSON schemas), topic extraction, and content analysis through multiple LLM providers such as OpenAI, Claude, vLLM, Ollama, and OpenRouter. Collaboration features include time-stamped comments and annotations, and the platform can automatically import media from local folders, S3, and SMB shares. It also supports a set of cloud ASR providers as alternatives to local transcription, giving teams flexibility between fully local processing and managed services while keeping the application running on their own infrastructure. Pricing varies by plan. Check the official website for current pricing.
