Speak real-life Korean, one scene a day. Koppa gives you one real Korean scene every day: ordering at a café, catching the last train, meeting your partner's parents. You learn what people actually say in that moment, then you say it yourself. MEET YOUR TUTOR Your Korean tutor has a personality straight out of a K-drama. He walks you through every scene line by line, listens as you speak, and celebrates with you when you get it. Easy for complete beginners: every lesson starts from zero, so your first day needs no Korean at all. START FROM ZERO • New to Korean? The Hangul tab teaches the alphabet from the first letter: write each one stroke by stroke with your finger, hear how it sounds, and find it in real words. • Forty letters in four short sets, with your progress on a chart and a time estimate for what is left. ONE SCENE A DAY • Understand: every line explained, so you know what it means, how it's built, and when to say it. New to hangul? Romanization is one tap away. • Speak: say every line out loud and polish your Korean pronunciation. • Rehearse: put the conversation back together and talk your way through the whole scene. • Casual: say the scene again the casual way, the Korean you hear in dramas and between friends. PRACTICE OUT LOUD • A course of everyday Korean phrases, grouped by situation: at the airport, at the bank, ordering coffee, making friends. • Say each phrase out loud and get a score with word-by-word notes, so you know which word to work on next. • Short rounds, and your best recording kept for every phrase, so a few minutes still moves you forward. Made for K-drama and K-pop fans, for your next trip to Korea, and for anyone who wants to say a Korean sentence out loud and know it landed. KEEP WHAT YOU LEARN • Every word you meet is saved to your vocabulary list, free, to review anytime. • Build a daily streak, one scene at a time. GO DEEPER WITH KOPPA PREMIUM • Speaking practice on every phrase in the course, after the free phrases you start with. • Missed-day review, so a busy week doesn't cost you your progress. Whether you want to learn Korean for a trip to Seoul, follow a K-drama without subtitles, sing along to K-pop, or talk with someone you love, Koppa teaches Korean conversation you'll actually use.
