How Hosiqo compares and tests toolsFinal recommendation
Shortlist aTrain when researchers transcribing recorded interviews for qualitative analysis matters most, and iMemo when transcribing lectures and interviews for later review matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Cross-platform AI recorder that turns meetings, lectures, and imported files into searchable transcripts and summaries.
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.

iMemo is an AI-powered audio note-taking app available on both iOS and Android that records, transcribes, and summarizes meetings, lectures, interviews, and personal notes. Users can capture high-quality audio directly in the app or import existing audio and video files in formats such as MP3, WAV, FLAC, and MP4, then have the content transcribed into searchable text across many languages. iMemo generates AI summaries from lengthy recordings, offers dual-language viewing for translation, and can identify issues and attributions within a conversation to help surface action items. Recordings and notes are organized into projects and folders with advanced search, and content can be exported in multiple formats including TXT, PDF, and several audio formats. iMemo records without joining calls as a bot participant, capturing audio on the device instead, and it emphasizes a privacy-focused approach where data stays on the device. The app is positioned for people who want to focus on a meeting or lecture without manually taking notes and review organized, searchable summaries afterward. Pricing varies by plan. Check the official website for current pricing.
