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.

About

CatchSay

Features
Read full description

CatchSay is an app for talking with ten AI friends who remember you. Senko and Dayeon for love and breakups, Pandacake and Seojun for work and career, Jaeha and Red Princess for money and business, Lila and Hyeonwoo for family and life, Harin and Mujin for the timing of a decision. Each friend has a different face, a different way of talking, and different things they know best. Pick the one who fits what's on your mind — and switch anytime. It's less a one-off result and more a relationship you keep beside you. Your friend remembers what you've talked about, so you never have to start from scratch. Ask what's really on your mind — "why is work not going well lately?" or "would this year be a good time to change jobs?" — and the answer comes from someone who knows your story. ■ Ten AI friends Love & relationships — Senko · Dayeon Work & career — Pandacake · Seojun Money & business — Jaeha · Red Princess Family & life — Lila · Hyeonwoo Decisions & timing — Harin · Mujin ■ They remember you Your past conversations carry over, so what they say fits you better the more you talk. ■ A face and a voice each Tap “Listen to voice” on a friend’s card and they’ll introduce themselves in their own voice. ■ Fictional friends with mystical talents All ten are fictional characters created by CatchSay. Some know saju, some work with tarot cards — each has a mystical knack of their own, so in conversation they may offer their own take on how today is flowing. It's a character speaking, not a prediction: nothing here foretells your future or replaces professional advice, and it's meant for fun and self-reflection. Talk to them the way you'd open up to a friend who knows you well. Subscriptions and token top-ups are available inside the app through the App Store.
