How Hosiqo compares and tests toolsFinal recommendation
Shortlist Allo when sales teams that want every outbound and inbound call recorded, transcribed, and logged to the crm automatically matters most, and aTrain when universities and public bodies needing gdpr-friendly local transcription matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Open-source offline transcription tool from the University of Graz that turns recorded meetings and interviews into text using Whisper and speaker detection.
Allo is an AI-powered business phone system aimed at sales teams, support, and operations that records every call, transcribes it in real time, and syncs the recording, transcript, and an AI-generated summary to a CRM automatically. Positioned as mobile-native and quick to set up, it focuses on letting reps spend time selling rather than logging calls. Each conversation is recorded with consent-message compliance options, transcribed with speaker identification, and condensed into a shareable AI recap. Allo can then draft personalized follow-up emails and SMS based on what was discussed. The platform includes an AI receptionist for answering inbound calls, voicemail transcription, multi-tag organization of calls, and team collaboration features such as cascade ring and warm transfers. Managers can pull call recordings and AI transcripts to find coaching opportunities, while reporting dashboards surface connection rates, conversion tracking, funnels, and heatmaps. Allo integrates with CRMs including HubSpot, Salesforce, Pipedrive, Attio, and Apollo, and exposes an MCP endpoint to connect the phone system to AI assistants. It is a live, operating product as of 2025/2026. 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.
