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.

CatchSay is an app for talking with twelve AI friends who remember you. Each friend has a distinct appearance, speaking style and interests. Explore the gallery and choose someone to talk with, including new friends Doyoon, Eunchae, Yoonseo and Haeun. 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. ■ twelve 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 twelve 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.

Verdict
The clearest difference is in-app purchases: Zetti at none against CatchSay's 6. CatchSay's advantage is update cadence (every 2 days vs every 5 days). On price, ads, device support and iOS requirement there is nothing between them.
