Nabi teaches you to read Hangul in about three hours, then keeps you reading — short lessons, spaced review, games that make the shapes stick, and a tutor you can talk to in Korean without an audience.
Hangul is alphabetic and unusually logical, so it's learnable in a single sitting instead of years of drilling. By the end of the opening course, Korean text stops looking like a wall and starts looking like words.
Every lesson feeds a spaced-review queue, so letter shapes and vocabulary resurface right before you'd forget them. When plain review gets dull, it turns into quick games that reward speed and recall.
Shadow native audio — slowed down, full speed, then from memory — and get scored on rhythm and pitch, the part of pronunciation that actually marks a learner as foreign. Recognition runs entirely on your device; your voice never leaves your phone.
Talk to an AI tutor in Korean about everyday topics. Speak into the mic, hear a spoken reply, and use the built-in "say it simpler" button when you get stuck. Translations stay hidden until you tap for them.
A separate culture track covers the etiquette most guides skip, including what's still true today and what's already fading. No audio, no microphone, no prior lessons — the one part of Nabi you can go through on a silent commute.
No ads, no paywall, no lesson locked behind a subscription. The tutor runs on a shared AI tier, and the Privacy Policy says plainly what that costs you.
