다시 Korean, again.
Studied Korean once and let it slip? Dasi picks up where you left off with about 10 minutes a day, then keeps going, all the way to TOPIK.
내일 다시 만나요.
See you again tomorrow.
Keys 1 and 2 work too.
That's a tiny taste of a Dasi session. Cards you mark 다시 배우기 come back until they stick.
하루 10분What a day with Dasi looks like
One short session a day, in the same order every time, so you never have to decide what to study.

새싹에서 숲까지From Sprout to Forest
Four levels that grow with you. A level opens when you know most of the words before it, so progress always means something.
작은 하루가 쌓여요Small days add up
연속 학습일A streak you can see
Green for a finished session, a gold slice for the minutes you managed. Even a busy day still counts for something.
솔직한 두 버튼Two honest buttons
No guessing between "hard" and "good". You either know it or you don't, and Dasi schedules the rest.
뽀모도로 타이머A built-in focus timer
A 25-minute Pomodoro starts on its own when you begin a session, open a grammar bite or a scene. When it rings, take a 5-minute break. You've earned it.
어디서나Anywhere
Every word and sentence has audio. Practice keeps working on a weak signal and syncs when you're back online.

자주 묻는 질문Questions
Who is Dasi for?
People who learned some Korean before, in a class, from a trip or from K-dramas, and want it back. You should be able to read Hangul. If you're starting from zero, the first level still works, it just moves quickly.
When can I start?
Dasi opens on the web first, then on iPhone and Android. Join the waitlist and we'll send one email the day it opens.
How does the sentence feedback work?
When you write your own Korean sentence, Dasi sends that sentence to an AI model (Claude, by Anthropic) and shows you a short, friendly correction. It's usually right and always explained, but it can make mistakes, so treat it like a helpful tutor rather than an official grader.
Does it help with TOPIK?
Level 4 focuses on TOPIK vocabulary and intermediate grammar. Dasi isn't affiliated with the official TOPIK exam, but it builds the words and patterns the exam expects.
Can I cancel?
Yes, anytime. You keep Premium until the end of the period you paid for. If you cancel during the free trial, you won't be charged. Refunds are covered in our refund policy.
Is my data sold or used for ads?
No. There are no ads and we don't sell personal data. The privacy policy lists exactly what's stored and why.
