Zetti - AI Note

Memos, ideas, schedules — just talk or type. Zetti auto-categorizes, responds, and logs everything. Slack sync, iCloud, calendar, reminders, widgets & briefings.

Zetti is an app that lets you take notes and organize your schedule through conversations with AI.

• Anything you say or type is understood by the AI and stored as meetings, schedules, to-dos, ideas, notes, or diary entries. When you ask questions, it answers based on what you’ve saved.

■ Conversational AI Input

• Speak or type naturally, and the AI interprets your intent and saves it to the right category.
• Phrases like “Meeting tomorrow at 2” or “I need to buy milk” are automatically classified as events or to-dos.
• When you ask questions, it refers to your stored notes and can even suggest follow-up questions. Try: “Summarize my key schedule for this week.”
• At your chosen morning/evening time, Zetti gives you a briefing based on your saved notes.
