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.

손안의 돌 하나를 문지르고 돌보는 앱. 걱정을 적는 칸이 없습니다. 쓰는 게 아니라 만지는 쪽으로 푼 앱입니다. 심장 삼위일체 문지름 엔진 이 앱에서 나머지는 전부 이것에 딸린 것입니다. 화면을 문지르면 색·소리·진동 셋이 한 몸으로 반응합니다. 문지르는 속도와 세기가 그대로 세 감각에 실립니다 돌보기 문지른 만큼 교감이 쌓이고 돌이 자랍니다. 온기 주기·밥 주기·씻기기·재우기·놀아주기 다섯 가지 의식이 있고, 하루라도 돌보면 연속 돌봄이 하루씩 늘어납니다. 끊겨도 비난하지 않습니다("다시 함께 시작해요"). 미니게임 알까기 · 물수제비 돌탑 쌓기 별 받기 무늬 기억 돌마다 잘하는 놀이가 다릅니다. 생김새(무게·납작함·매끈함·부피)에서 능력치가 나옵니다. 설계에서 중요한 건 모든 돌의 유불리 합이 0이라는 점입니다 각 돌의 4게임 평균을 기준으로 빼서, 무거운 돌은 알까기에 강한 대신 다른 데서 손해를 봅니다. 모으기 손돌 53종에 오라·배경·소품·문지름 소리·친구까지. 문지르고 돌보면 P포인트가 쌓이고, 레벨업과 가챠·상점으로 풀립니다. 완성한 돌은 이미지 카드로 만들어 공유합니다.
