Shortlist Efficlose when recording calls without a visible bot via the chrome extension 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.

Open-source offline transcription tool from the University of Graz that turns recorded meetings and interviews into text using Whisper and speaker detection.
Efficlose is an AI meeting platform that captures, transcribes, and summarizes conversations through a combination of a Chrome extension, a desktop app, and a web platform. Its Chrome extension is positioned as a way to record meetings without a bot joining the call, capturing audio locally in the browser so no extra participant is announced or shown in the meeting; users can choose to capture a single tab, a specific window, or the full screen, and start or stop recording manually rather than relying on calendar triggers. For users who prefer automated joining, the desktop app and platform can connect to a calendar and send a bot to scheduled meetings on Zoom, Microsoft Teams, and Google Meet. Recordings are transcribed automatically with speaker identification, and the platform generates summaries with key decisions, next steps, and assigned action items. It also offers meeting search across past recordings and an AI assistant for querying conversations, plus integrations with business tools such as Salesforce, HubSpot, Slack, and Notion. Efficlose is aimed at teams across sales, customer success, recruiting, engineering, and project management who want flexible recording options and structured meeting outputs synced into their existing tools. 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.
