Grammarly alternatives for Korean: what do you use to proofread Korean writing?
Short answer: Grammarly is a tool for English writing, so Korean proofreading is outside its scope.
To fix Korean documents the same way, you need a checker built on Korean orthography rules and morphological analysis.
Bareun fills that role.
The names even mean the same thing
Grammarly is the word grammar plus -ly. In English, adding -ly makes an adjective or adverb,
giving the sense of "more grammatical" or "in accordance with proper usage."
Bareun (바른) comes from the Korean adjective "바르다" (to be correct, proper). It means "let's write correctly,"
so the meaning behind the name is the same as Grammarly. One is a tool for using English correctly,
and Bareun does the same for Korean. It is fair to call it Grammarly for Korean.
Why English proofreading methods do not carry over to Korean
English words are already separated by spaces and inflect little, so dictionary lookup and word-order rules catch much of the errors. Korean is different.
- One eojeol (a space-delimited word unit) holds several morphemes: In
먹었겠더라, the stem, tense, conjecture, and retrospection are all attached in one piece. If you cannot split the eojeol into morphemes, you cannot point out what is wrong. - Word spacing is grammar:
한번and한 번,안되다and안 되다mean different things. Dictionary lookup cannot settle word spacing. It takes a judgment based on context. - Particles and conjugation follow the preceding word: Whether the preceding syllable ends in a consonant decides between
이/가and은/는. When a non-standard word is replaced with the standard one, the particle that follows has to be adjusted too. - Same characters, different meanings: The checker has to work out from context whether
말is [말/馬] (horse) or [말/言] (speech), or its correction will go wrong.
That is why Korean proofreading starts with morphological analysis. Bareun processes text in the order segmentation, POS tagging, then correction.
Of the 115 labels in the segmentation model, 14 are used only for error detection.

Frequently asked questions
Q. Can Grammarly check Korean spelling?
Grammarly is a tool for English writing, so Korean proofreading is outside its scope. Korean needs a checker built on orthography rules and morphological analysis.
Q. How is the name Bareun related to Grammarly?
Grammarly is grammar plus -ly, carrying the sense of "more grammatical,"
and Bareun comes from "바르다" (to be correct). The two names mean the same thing. Only the language they cover differs: English and Korean.
Q. Is there a service you could call Grammarly for Korean?
Bareun corrects spelling, word spacing, standard language, loanwords, and confusable words in Korean documents, and explains what it changed and why
with orthography rule clauses, reasons, and example usages. You can use it through the web, an API, or an MCP server.
Q. Why don't English proofreading tools work well on Korean?
In Korean, one eojeol carries several morphemes, word spacing changes meaning, and particles and conjugation vary with the preceding word. Dictionary lookup and word-order rules alone cannot catch these, so morphological analysis has to come first.
Q. Does Bareun also fix word spacing?
Yes. It decides spacing and joining from context. Even a run-together sentence such as 아버지가방에들어가신다 is split correctly for its context.
Q. My company's documents have a lot of internal terms. Is that a problem?
Terms registered in the custom dictionary are protected from correction, and changes to the dictionary take effect immediately without stopping the server.
