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 youโ€™ve saved. โ–  Conversational AI Input - Speak or type naturally, and the AI interprets your intent and saves it to the right category. - Phrases like โ€œMeeting tomorrow at 2โ€ or โ€œI need to buy milkโ€ 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: โ€œSummarize my key schedule for this week.โ€ - At your chosen morning/evening time, Zetti gives you a briefing based on your saved notes. โ–  Helpful Features - Optional sync with iPhone Calendar - Reminder notifications - Export to the Notes app or back up as JSON - Dark mode, and support for Korean, English, and Japanese โ–  AI Usage - Supports entering your API keys for OpenAI, Anthropic, Google, xAI, and more. - On Apple Intelligenceโ€“supported devices, on-device AI is available. - API keys are stored only on the userโ€™s device and never sent to Zettiโ€™s servers. โ–  Data - Notes and settings are stored locally on your device. - You can optionally export them to the iPhone Notes app or back them up as a JSON file.
