How Hosiqo compares and tests toolsFinal recommendation
Shortlist CloudTalk when reviewing and coaching sales calls using ai summaries, sentiment, and talk ratios matters most, and aTrain when universities and public bodies needing gdpr-friendly local transcription matters most. Try them side by side on real calls before deciding — needs vary by team.

CloudTalk is a cloud-based business calling and call-center platform that pairs voice infrastructure with an AI Conversation Intelligence layer for sales, support, and operations teams. On top of its phone system (international numbers, IVR, call routing, recording, dialers, SMS, and WhatsApp), CloudTalk automatically converts recorded calls into multilingual transcripts and stores them in a searchable interaction database. Its AI then generates instant call summaries and smart notes, applies automatic tags, extracts the key topics discussed, and scores calls against custom criteria. Sentiment analysis interprets the mood of each speaker segment by segment, classifying calls as positive, neutral, or negative, while talk/listen ratio tracking surfaces coaching opportunities across agents. Summaries and notes can sync into CRMs such as Salesforce, HubSpot, and Pipedrive through CloudTalk's broad integration catalog. Conversation Intelligence is available as a paid add-on across CloudTalk's calling plans. It is aimed at teams that handle high call volumes and want to review, analyze, and coach on conversations at scale rather than manually.

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.
