Master Korean Grammar Through Practice, Not Memorisation.
A growing library of specialist modules covering particles, speech levels, honorifics, and connective endings. AI-powered explanations after every exercise.
You are introducing yourself at a study group.
저 이번 학기에는 한국에서 공부해요.
Correct! In an introduction, 은/는 sets the topic: "As for me..."
Built for the grammar that actually trips you up.
Korean grammar textbooks teach rules. KoreanLab teaches the decisions: when to use 은/는 vs 이/가, why 에서 and not 에, how formality actually works in conversation.
Each module places you in real contexts and uses spaced repetition to make the right choice automatic. After every exercise, an AI tutor is ready to explain further.
How KoreanLab helps you learn grammar that sticks
Contextualised Practice
Every exercise places you in a real Korean conversation. You choose between particles or structures, get instant feedback explaining exactly why your choice was right or wrong, and see the full sentence with translation.
AI Chat Tutor
Stuck on an exercise? Ask the AI tutor for help. It knows the exact grammar point, the context you are working in, and your personal strengths and weaknesses. Every explanation is tailored to where you are in your learning journey.
Spaced Repetition
Our SM-2 algorithm schedules reviews at the perfect intervals to move grammar from short-term recognition to long-term recall. Get it right and the interval grows. Get it wrong and you review sooner. Your weakest areas get the most attention automatically.
Progress Insights
Track your accuracy across every particle and grammar point. See which contexts trip you up most, identify your most common confusions, and get personalised recommendations for what to review next. Your dashboard shows streaks, activity trends, and module completion at a glance.
