AutoMemo (オートメモ) is a transcription AI developed, sold, and supported by Sourcenext Corporation in Japan. It is built around a multi-surface approach: users can capture audio through a web browser app, a dedicated smartphone app, or standalone hardware voice recorders (the AutoMemo S and AutoMemo R devices), and the captured audio is automatically converted to text. The service uses a Whisper-based speech recognition engine, automatically inserts punctuation, removes filler words such as Japanese hesitation sounds, and recognizes speakers so that transcription results are divided into speaker blocks. On top of the transcript, AutoMemo can automatically generate summaries and extract to-do items and deadlines, and it has added features such as AI-generated titles for recordings. Audio and transcripts are saved to the cloud for later editing, searching, and sharing. AutoMemo positions itself for business meetings, interviews, and lecture capture in Japanese-language workflows, and offers a limited free transcription allowance with paid plans for higher usage. It remains actively developed and marketed in 2025/2026. Pricing varies by plan. Check the official website for current pricing.

Thoth is a native macOS application, created by Matthieu Veinhard, that records, transcribes, and summarizes meetings entirely on the user's device. It captures both microphone and system audio so it can record both sides of online meetings on platforms such as Zoom, Teams, and Google Meet, and it provides live transcription with on-device speech-to-text. An on-device engine detects and color-codes individual speakers in the transcript, and the app supports a large number of languages via Whisper-based transcription. After a meeting, Thoth extracts notes, action items, and key decisions, and lets users choose between several on-device models or supply their own cloud API key, with an on-device anonymization step that can redact sensitive information before any optional cloud processing. Output can be exported to formats including PDF, Word, Markdown, and timestamped JSON. Because the app has no server and no user database, the company emphasizes that there is nothing to breach or hand over. Thoth requires Apple Silicon and is aimed at privacy-conscious professionals, those handling confidential information, and neurodivergent users who benefit from automatic capture, and it is available on the Mac App Store with an iOS beta in progress. Pricing varies by plan. Check the official website for current pricing.
