Real-time AI guidance and agent-assist platform that coaches contact-center and sales agents live during calls.
Open-source offline transcription tool from the University of Graz that turns recorded meetings and interviews into text using Whisper and speaker detection.
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.

aTrain is a free, open-source desktop application for offline speech transcription, developed by researchers at the Business Analytics and Data Science Center of the University of Graz in Austria. It provides a graphical interface around OpenAI's Whisper model (via the faster-whisper implementation) so users with no programming experience can transcribe recorded meetings, interviews, lectures, and other audio. Because all processing happens locally on the user's own computer, no audio or text is uploaded to any server, which makes it well suited to privacy-sensitive and GDPR-conscious environments such as universities, public institutions, and research teams. aTrain supports a wide range of languages and adds speaker detection through pyannote.audio so contributions from different participants can be separated. Transcripts can be exported in formats compatible with qualitative-analysis software such as MAXQDA, ATLAS.ti, and NVivo. It runs on Windows (including a Microsoft Store distribution) with GPU acceleration on NVIDIA hardware, and is distributed under the AGPL-3.0 license. It is best for researchers, academics, and organizations that need accurate, local, no-cloud transcription of recorded conversations. Pricing varies by plan. Check the official website for current pricing.
