If you're writing in Korean and need to catch grammar mistakes, this checks for the stuff that trips people up: 되 vs 돼, spacing around dependent nouns and auxiliary verbs, particle misuse, and punctuation. It's built around National Institute of Korean Language standards and explains why something is wrong, not just that it's wrong. The confidence levels are helpful since Korean grammar can be contextual. It knows to be stricter with formal documents than blog posts and won't flag intentional colloquialisms. Works for everything from code comments to business docs. The reference files cover common error patterns if you want to understand the rules yourself.
