What AI Feedback on Korean Writing Actually Looks Like
A worked example of sentence-by-sentence Korean writing correction: what was wrong, why it was wrong, a model answer, and the TOPIK II writing rubric scored out of 15.
Marking a multiple-choice question is easy. Telling someone why their own Korean sentence sounds off is the hard part, and it is the part almost no Korean-learning app does. This page shows the exact output you get, on a real task.
The answer below was written for this demonstration, not submitted by a student. Your own feedback is generated from whatever you write.
The taskLevel 3 · TOPIK 3 target
당신의 취미를 소개하고, 그 취미를 좋아하는 이유를 쓰세요. Introduce your hobby and explain why you like it.
Sentence by sentence문장별 첨삭
Every sentence is checked on its own. Correct ones are confirmed rather than skipped, so you learn what you already got right.
✓ NO CHANGE NEEDED
제 취미는 등산이에요.
Correct and natural. 제 취미는 ~이에요 is the standard frame for introducing a hobby, and 등산 takes 이에요 because it ends in a batchim.
저는 주말마다 친구하고 산에 갔어요.
저는 주말마다 친구하고 산에 가요.
주말마다 means "every weekend", so this is a repeated habit and Korean keeps it in the present tense: 가요. The past tense 갔어요 would tell the reader you used to do this but have stopped.grammarmajor
산 위에서 보는 경치가 너무 예뻐서 기분이 좋아집니다.
산 위에서 보는 경치가 아름다워서 기분이 좋아져요.
Two things. 예쁘다 is normally used for people or small, cute things; for scenery Korean prefers 아름답다. And you switched from 해요체 (가요) to 합니다체 (좋아집니다) mid-paragraph — pick one speech level and hold it to the end.vocabularyminor
그리고 등산은 건강에 좋기 때문에 스트레스도 풀려요.
그리고 등산을 하면 건강에도 좋고 스트레스도 풀려요.
The cause and effect does not hold: being good for your health is not the reason stress goes away. These are two parallel benefits, so join them with -고 rather than -기 때문에.cohesionminor
Overall총평
SCORE 82 / 100
What worked. All four sentences stay on the task and you gave a concrete reason for liking the hobby. Your -아/어서 cause-and-effect linking is accurate, which is often the first thing that breaks at this level.
What to fix next. Two habits to build: use the present tense for repeated actions, and choose one speech level (해요체 or 합니다체) at the start of a paragraph and keep it.
Model answer모범 답안
Not a rewrite of your text into something unrecognisable — the same content at the level you were aiming for.
제 취미는 등산이에요. 저는 주말마다 친구하고 산에 가요. 산 위에서 보는 경치가 아름다워서 기분이 좋아져요. 그리고 등산을 하면 건강에도 좋고 스트레스도 풀려요.
TOPIK II writing rubric쓰기 채점 기준
For TOPIK II writing tasks the same answer is also scored against the official criteria, so you can see which band you are actually in.
Criterion
Score
Comment
Content
4 / 5
Both required elements are present: the hobby and a reason. One more supporting detail would reach full marks.
Organization
4 / 5
Clear order — introduce, describe, then give reasons. The final sentence bundles two ideas that could be separated.
Language
3 / 5
Vocabulary fits the level, but the tense slip and the mixed speech levels cost marks here.

The Korean — your sentence, the correction, the model answer — always stays in Korean. The explanations come back in English, Japanese, Chinese, Vietnamese, Indonesian, Spanish or Russian, whichever you set.
