GJK was created based on a single question.


"Why so many Korean learners can't speak with native Koreans even after over a year of learning Korean?"

Over the past several years, we have seen many Korean learners struggle to communicate in Korean even though they've learned Korean for more than a year.

Obviously, Korean is not an easy language, but we discovered fundamental problems with Korean learning services.

They are either unengaging or poorly organized, so they make you lose motivation and easily give up learning Korean.

But, we are different. We are confident that we can give you more engaging, better, and more effective courses and make you speak the most natural Korean.

We promise that you will learn fast and have fun.

Thank you for letting us be part of your Korean learning journey.

We received a prize in a big contest for creating excellent Korean courses.



Korean teacher Kun

Hi there, I'm Kun. My strength in teaching Korean is my ability to explain complex ideas in a way that's easy to understand. When it comes to learning a new language, it's crucial to build a solid foundation. Without a strong base, you'll likely struggle later on, and you might have to study from scratch again. That's why I take the time to break down each expression and grammar point, making sure you understand everything thoroughly.

I'm confident that with my help, you'll establish a strong foundation in Korean and make excellent progress. My goal is to help you establish a firm foundation in Korean, so you can confidently communicate with native Korean speakers.

Korean teacher Jin

Hello, I'm Jin. I believe that learning Korean should be an enjoyable experience, and that's why I strive to make my lessons both informative and fun. To make the learning process more enjoyable, I focus on teaching practical expressions that Koreans use in their daily lives.

Additionally, I take the time to explain the context in which each expression is commonly used, helping you to gain a deeper understanding of the language. My goal is to make learning Korean so enjoyable that you'll be excited to continue studying and improve your language skills even further.

Korean teacher Jiyong

Hello, I'm Jiyong. I'm a native Korean born and raised in Korea, but I have experienced many different cultures while living in other countries. Currently, I can speak Korean, English, Japanese, and a little bit of French. These backgrounds have been helping me teach Korean from many different perspectives, making the learning process more engaging and effective. 

I enjoy learning languages on YouTube or watching movies. I believe the most effective way to learn a foreign language is to watch videos, listen carefully, and try to understand them. Then, repeat what native speakers say in the video, just like the GJK lessons! We have prepared compact, easy, and fun lessons for you. I'm confident that after taking GJK courses, you'll see significant improvement in your Korean skills!
