Shortlist AutoMemo when capturing and transcribing in-person business meetings matters most, and Sonnet AI when recruiters documenting candidate interviews with structured templates matters most. Try them side by side on real calls before deciding — needs vary by team.

Bot-free AI meeting assistant that records device audio, transcribes, and generates structured notes and action items across major conferencing apps.
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.

Sonnet AI is an end-to-end AI meeting assistant and notetaker that captures conversations without sending a separate bot into the call. Instead of joining as a visible participant, it records high-quality audio directly from the user's device, which lets it work across Zoom, Google Meet, Microsoft Teams, Slack and Discord without per-platform integrations or plug-ins. Once a meeting ends, Sonnet produces a transcript and a structured set of notes, pulls out action items with potential assignees and deadlines, and stores everything in a searchable conversation database so users can revisit past discussions. It offers a template gallery aimed at specific contexts such as sales, recruiting, legal and medical meetings, along with customizable note layouts that support elements like tables and concept maps. Additional features include meeting reminders and preparation tools, participant relationship tracking, and the ability to keep CRM records updated from meeting content. It is designed for professionals and teams who want hands-free note capture and reliable post-meeting follow-up without disrupting the flow of a live conversation. Pricing varies by plan. Check the official website for current pricing.
