The 5 Best and Brightest Tools for Checking Korean Grammar

Grammar, especially when it vastly differs from your native language, can be a difficult hurdle that you need to surmount if you want to really become fluent in Korean.

But online Korean grammar checkers can help you learn Korean grammar by pinpointing where you’re struggling in the way of sentence structure, composition, semantics, morphology, honorifics and all that jazz.

So let’s check out some checkers to help you in your language learning journey!


Are Korean Grammar Checkers Worth Using?

The short answer would be yes and no.

It’s no secret that many grammar checkers tend to work poorly when it comes to East Asian language systems. It can be difficult to detect complex sentence structures with grammar checkers as well.

However, that doesn’t mean that you should avoid Korean grammar checkers altogether. They can indeed serve a purpose on your language learning journey.

To put it simply, some grammar checkers can be very useful some of the time.

We found a handful of Korean grammar checkers that work well and tend to be more accurate than other grammar checkers. While these sites and apps shouldn’t be used to check your grammar 24/7, they can be useful some of the time. If you need to proofread an essay and double-check the paper for mistakes, for instance. They can also be handy for quickly checking the grammar of short paragraphs or individual sentences when chatting online in Korean.

To prevent grammar checkers from becoming a way to avoid studying grammar, and to make sure that you’re not internalizing the quirks of the checker you’re using rather than Korean grammar as a whole, try to incorporate as many examples of authentic input into your study routine as possible.

This can be done in many ways. For example, you could read a graded reader, like Olly Richard’s Short Stories in Korean for Intermediate Learners, to break down each sentence and help you understand how it translates into your native language. The stories will also get progressively harder as you go along, so you’ll constantly be challenged to improve your grammar and vocabulary.

Or, you could try FluentU’s language learning program, where you’ll have access to a library of native media that’s categorized by difficulty and topic of interest. The media library has a varied collection, including movie clips and trailers, music videos, news segments, vlogs, interviews and more.

Each video is equipped with a number of learning features, like interactive subtitles that allow you to hover over or click on any word to see a translation or add it to your flashcards list. These translations include detailed grammar information, and the contextual dictionary also lets you see other videos where the word appears with that form and meaning.

Learn Korean – Grammar

Android | iOS


Sometimes an app is just way more useful than an in-browser checker, especially if you want to learn about grammar concepts and correct your own grammar on the go.

This app isn’t a grammar checker in the traditional sense, but it can certainly be used as one. For the most part, this app is an instructional guide to learning different aspects of Korean grammar.

However, the search function can be very useful to someone who wants to check the grammar of a phrase or short paragraph they’ve written. Simply look up keywords to see the correct grammatical uses of them in Korean.

For example, if you look up the phrase “Nice weather, isn’t it?” you’ll then be able to see how that phrase is correctly written and where in the sentence each word is located. You can also take lessons on different niche aspects of grammar and quiz yourself on your knowledge.

The app is free to use with in-app ads and is perfectly suitable for all levels of learners, though advanced learners may find that the grammar concepts explored aren’t complex enough to be a challenge.

kGrammar App

Android | iOS


Here we have another awesome Korean grammar app that’s definitely more on the traditional side of grammar checkers, and that has a ton of additional great features.

With kGrammar, you can search various words and phrases to see the proper grammar structure in Korean, search different grammar topics, save topics to study for later and access an expansive table of irregular verbs.

The sentence analyzer is a great little grammar checker that’s pretty accurate and easy to use. Plus, the app has a clean and attractive interface void of any distractions other than the occasional ad. The real kicker to this app is that the navigation is entirely in English, as are the corrections in the sentence analyzer, so you won’t have to struggle to understand the grammar corrections given to you.

kGrammar is 100% free to download and use but does contain some in-app ads. Since you can toggle between Korean and English in this app, it’s perfect for all levels of learners.

You can compare your own writing to the corrected writing side-by-side for reference.

Since this interface is mostly in Korean, it may be a bit too challenging for beginner learners to use. Still, intermediate and advanced learners can definitely get some serious help from it.

The NounPlus Korean grammar checker is free to use.

Korean Grammar Dictionary


Korean Grammar Dictionary is designed more for students who are studying Korean at a college level.

This grammar checker, which is really more of a grammar reference, can be a bit confusing at first, simply because there are so many options. Start by selecting an aspect of grammar from the “Category” box. You’ll then be directed to different word themes in Korean and ultimately individual vocabulary. Once selected, the result will be an in-depth definition of the word or phrase and an example of how it would fit into a sentence grammatically. You can also search by textbook lesson and series.

Since this option is a bit more advanced, we’d suggest that beginner learners look elsewhere. Korean Grammar Dictionary is free to use.


Ready to take your grammar skills to the next level?
