Learn Korean from absolute zero — structured, simple, and completely free. OLK is a Korean learning app built by a learner, for learners. Instead of overwhelming you with random content, OLK follows a clear path from the Korean alphabet all the way to grammar and conversation skills, aligned with the TOPIK I curriculum. LEARN HANGUL (THE KOREAN ALPHABET) Start with the basics. Learn all 19 consonants, 21 vowels, and double letters. Every character includes audio pronunciation so you can hear exactly how it sounds. Covers batchim (final consonant) rules, linking sounds, and stroke order. 1,300+ KOREAN VERBS Browse the largest beginner-friendly verb collection with English meanings, usage hints, and frequency rankings from official Korean language research. Tap any verb to see its present, past, future, and progressive conjugations — hidden by default so you can test yourself first. 435 KOREAN ADJECTIVES A complete adjective reference with meanings and conjugations. Includes a curated TOPIK I set with present, past, and attributive forms, plus a searchable list of 435 adjectives from the official NIKL/TOPIK vocabulary database. GRAMMAR & CONJUGATION GUIDES Clear, visual explanations of Korean grammar patterns including polite form, vowel contraction, irregular verbs and adjectives, negation (안/못/없다), and more. Every rule comes with examples and audio. NEGATION (부정 표현) Master all three ways to say "not" and "can't" in Korean — short forms, long forms, word opposites, and the tricky 하다 verb splitting rules. QUIZZES FOR EVERY SECTION Multiple choice and type-in quizzes for Hangul, verbs, adjectives, and negation. Active recall — not just matching games. Track your progress with scores after every round. AUDIO FOR EVERY WORD Tap any Korean word anywhere in the app to hear its pronunciation. Powered by your device's built-in text-to-speech — no internet required.
