A K-drama on your phone. He calls, you answer in Korean.

Absolutely. Episode 1 starts with your very first 안녕, and Junho adapts to your level, so total beginners and TOPIK learners both feel at home.

Junho calls you, just like a real phone call. He speaks first in Korean with subtitles on screen, then waits for your line. Tap the mic and answer. Each episode is one call.

Chingu is built for learning Korean through a story: episodes with a scene and his voice, lines you say out loud, his texts between episodes, roleplay scenes, and a word book of every phrase you've said.

Chingu+ opens everything: all three seasons, roleplay scenes, daily texts with Junho and your word book. Start with a 7-day free trial, then choose yearly or monthly. Cancel anytime in your iPhone settings.

Korean learners 17 and older who love K-dramas. Junho and every character in Chingu are AI-generated and fictional.

Your voice and messages are processed by OpenAI only to run Junho's calls and replies, and only after you agree in the app. We never sell your data, and you can delete your account and your data at any time.

Chingu supports English, Japanese, French, German, and Traditional Chinese as your native language. Junho speaks Korean and adapts his explanations to your language.

Chingu is currently available on iOS. Android and web versions are on our roadmap.
