Chime Note (CHIME NOTE Pro) is a physical AI voice recorder paired with companion software for iOS, Android, and the web (CHIME Web at app.chimenote.com). Audio is captured by pressing a button on the pocket-sized device, which can attach magnetically to a phone via MagSafe and records calls and everyday conversations, storing audio locally before it is processed into text. The app uses GPT-4o for transcription and ChatGPT-based AI summaries, both offered as free, unlimited core services. Premium, pay-as-you-go features include real-time transcription during recording and voice translation, with the multi-language chatroom function supporting automatic translation across up to 107 languages. There is no mandatory subscription; purchased usage time does not expire. The device costs $189.99 (regularly $239.99) and ships with a one-year warranty and 30-day returns. Chime Note is marketed to students, professionals, neurodiverse individuals, and travelers who want hands-free capture of meetings, interviews, and conversations. No integrations with Zoom, Microsoft Teams, Google Meet, or calendars are documented.

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.
