How Hosiqo compares and tests toolsFinal recommendation
Shortlist AutoMemo when capturing and transcribing in-person business meetings matters most, and Sotto when privacy-first transcription of imported audio recordings on-device matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Sotto is a native macOS voice-to-text dictation app that turns speech into text system-wide using local AI transcription models.
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.

Sotto is a native Swift dictation app for macOS 13 and later that converts speech to text in real time. It works as a system-wide push-to-talk layer: the user holds a hotkey, speaks, and Sotto inserts clean text into whatever app is in focus, from Slack and Notion to Xcode and email fields. Audio is transcribed by local engines, including OpenAI Whisper models (Tiny through Large V3 Turbo and Distil Large V3) and NVIDIA Parakeet v2/v3, so by default recordings never leave the Mac; users can optionally connect cloud providers such as OpenAI or Groq with their own API keys for added accuracy. Beyond live dictation, it can import and re-transcribe audio files, supports 90+ languages, keeps a searchable history of recordings with timestamps, and offers a custom vocabulary dictionary. One-click AI processing can rewrite, summarize, translate, or reformat dictated text. It is aimed at developers, writers, and privacy-conscious professionals who want fast, local voice input rather than a cloud meeting-bot service.
