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. ■ 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 ■ AI Usage - Supports entering your API keys for OpenAI, Anthropic, Google, xAI, and more. - On Apple Intelligence–supported devices, on-device AI is available. - API keys are stored only on the user’s device and never sent to Zetti’s servers. ■ 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.

Gratitude Practice

Write three things you're grateful for and you run dry fast. Good weather, a tasty lunch, my health. There's only so much you have. But some memories stay sharp for months. The time someone quietly helped you when things were hard. The day someone thanked you, and meant it. What passes between people stays. 'Gratitude Practice' is built on that difference. *Two things, side by side Grateful today — written fresh each day. Starts with three fields; add or remove as you like. Revisit — coming back now and then to the same story. Write down a time you were thanked, or helped, as three or four bullet points, then sit with the feeling for a minute or two. *Why the same story Revisiting isn't about finding more to read. It's about letting the feeling from back then come up again now. Think of a song you love. Choosing a new one each time means spending the first minute deciding whether you like it. A familiar one puts you there within two bars. *What isn't here No streaks. No monthly counts. Days you miss go unmentioned. An empty day is just empty. No prompts, no quote feed, no AI replies. Just a title and empty fields. No account. You'll never see a sign-in screen. No ads, no subscription. *Your entries stay yours Stored on this device and in iCloud. Nothing is sent to a server, and nothing is collected. Change phones and it comes back on its own. Export any time as JSON or Markdown. Lock it with Face ID. *Where this comes from The two-part structure comes from a gratitude practice described by neuroscientist Andrew Huberman in a 2021 episode of the Huberman Lab podcast.
