About

michi

Read full description

Michi is a next-generation notes app that helps you collect your everyday thoughts, learnings, and emotions—and reflect on what’s happening inside you. Most people don’t stick with note-taking for one simple reason: capturing and organizing takes too much effort. And even when you do write things down, they often disappear into a pile you never use again. Michi is built to solve that at the root. 1. Capture with zero friction Save the moment your mind moves—instantly—with text, voice, or images. You don’t need to “write neatly” or organize as you go. That’s not your job. Before a good idea evaporates, catch it. 2. Let AI handle the organizing AI automatically tags and links your notes, connecting related ideas for you. No folders to maintain, no rules to design—just focus on capturing what matters. 3. Watch “you” take shape See how your thoughts connect through a visual graph. Recurring themes, shifts from months ago, growing interests, and unexpected links start to emerge. Even a quick glance can reveal hints about who you are right now. 4. A map of you, built from your notes Michi isn’t just about storing notes—it’s about using them. Over time, your daily entries evolve into a “map of you” that supports reflection, better choices, and deeper self-understanding. Sync across devices & export Access the same notes anywhere with seamless cross-device sync. Export via GitHub anytime—so you can keep your data portable and connect it with other AI tools your way. Pricing Michi is available as a monthly subscription (details in the app). Terms of Use (Apple Standard EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
