Prubi โ€” the AI notes app that gets prettier as you write. One line becomes a plan, and Prubi reminds you before you forget. A line a day, in Korean โ€” write one line about your day and see it as natural Korean phrases: the sentence, how it sounds, and what each part means. Listen, read along, then hide it and write it in Korean yourself. WHY YOU'LL WANT TO OPEN IT โ€ข Share as one card, no link โ€” today's line turns into a picture card. Anyone can read it, even without the app. โ€ข 16 pixel friends โ€” as your writing days add up, a new friend drops by and walks along the bottom of the screen. Can you collect them all? โ€ข A desk that grows with you โ€” 28 papers, tapes, props and friends to decorate every day, nothing to buy. โ€ข One line is enough โ€” no long entries, and skipping a day is fine. Start light with 7 Days of Gratitude. EVERYDAY PROBLEMS, MADE EASY โ€ข Jot it before it slips away โ€” write straight from Home. No folder to pick first. โ€ข Notes become plans โ€” write one line, tap "Let Prubi sort this", and the date and time land on your calendar. โ€ข Check it, color it, remind me โ€” checklists, 6 colors and reminders. โ€ข Your week at a glance โ€” weekly planner, a 24-hour day view and D-day. โ€ข "Where did I write that?" โ€” ask, and the AI finds it in your own notes and shows exactly which notes it read. BUILT TO TRUST, BUILT TO LAST โ€ข A vault only you can open โ€” passwords, account numbers and ID photos are encrypted on your device before upload; the server keeps only ciphertext. โ€ข Write on your phone, continue on PC โ€” same account, same notes on phone, PC and tablet. โ€ข 16 languages ยท no ads ยท no data selling ยท your notes are not used to train AI models. โ€ข Export notes to Word, PDF or Excel, and delete your account any time. START WITH ONE LINE TODAY Create your free account now โ€” every line you write is saved to it, so nothing is lost even if you change phones. Free to start. When you want to go deeper, continue with an annual or lifetime plan inside the app. On a computer, pick up right where you left off at prubi.online with the same account. Made by Gonggansai
