Open-source offline transcription tool from the University of Graz that turns recorded meetings and interviews into text using Whisper and speaker detection.
Cresta is an enterprise customer-experience AI platform that unifies human and AI agents across voice and digital channels. It captures conversations through integrations with major contact-center systems such as Genesys, NICE, Salesforce, Twilio, and Amazon Connect, then analyzes those interactions at scale to surface behavioral insights and deliver real-time guidance. Its Agent Assist listens to live conversations and provides agents with in-the-moment suggestions, knowledge, and next-best actions, while a Knowledge Agent proactively surfaces context-aware answers without manual prompting. Cresta's conversation intelligence analyzes 100% of interactions to identify the behaviors that drive outcomes, and its automated quality management scores conversations across the board so supervisors gain visibility without manual sampling. The platform also offers autonomous AI agents that can resolve customer conversations end to end, plus an Agent Operations Center that gives supervisors real-time visibility and intervention tools across both human and AI-led conversations. Cresta is built for large enterprise contact centers in industries such as financial services, travel and hospitality, telecommunications, insurance, and healthcare that need real-time assistance, coaching, and analytics at scale.

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.
