Notis AI is a voice-first productivity assistant that integrates deeply with Notion and messaging apps like WhatsApp, Telegram, email or Raycast to let you dictate, capture, and organize notes, memos, tasks, meeting minutes, and more — all from wherever you are, without opening Notion explicitly. You can send a voice message, forward an email, text, or snap a photo, and Notis transcribes or processes the content (including for multiple languages), structures it into Notion databases, extracts action items, generates summaries, and even sends follow-ups or reminders automatically. It supports both disposable workflows (quick one-off tasks like summarizing a meeting or drafting an email) and persistent automation workflows (where Notis monitors databases, runs scheduled prompts, or responds to triggers so it behaves like an “agent” in your workspace).
