How Hosiqo compares and tests toolsFinal recommendation
Shortlist Exec when practicing cold calls, discovery, and objection handling safely matters most, and aTrain when universities and public bodies needing gdpr-friendly local transcription matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Exec is an AI roleplay and training platform designed to help sales reps, leaders, and support staff practice high-stakes conversations before they happen with real customers. Its core function is generating voice-based AI characters that simulate buyers and other counterparts, complete with industry context and customizable traits, so reps can rehearse cold calls, discovery, negotiation, and objection handling in unscripted, dynamic conversations. The platform supports custom scenario creation and includes screen-sharing functionality so reps can practice product demos and presentations, not just talk tracks. After each roleplay, Exec provides instant performance insights, including actionable improvement tips and an AI coach that can explain scores, surface growth areas, and run short follow-up sessions to work through specific gaps. For managers and enablement teams, Exec offers analytics dashboards tracking skill development over time, performance trending, leaderboards, certification, and integration with existing learning management systems. It maintains SOC 2 Type II certification and states it does not use customer data to train its models. Exec is aimed at enterprise sales and revenue teams that want to close the gap between training content and real behavior change through repeated, measurable practice. Pricing varies by plan.

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.
