By Kyujun Choi, from the App StoreDescription by Kyujun Choi Written by the developer, not by AppBrain. Click to read.
Most apps teach you Korean words and grammar, but you freeze the moment you have to speak. And no other app corrects your 존댓말 (polite speech) and 반말 (casual speech) — the honorifics that native Korean speakers notice right away. Ksori is built to fix exactly that.
WHY KSORI
Speak Korean from day one. Have real voice conversations with an AI Korean partner on any topic — daily life, work, K-pop, or any keyword you choose. Not fixed scripts. A real conversation that talks back.
Korean honorifics correction — the feature no other app has. Ksori detects when you mix up 존댓말 and 반말 and corrects it. This is the wall that English-based Korean apps never cross, and it is our number one priority.
Corrections that stick. After every Korean conversation you get correction cards — pronunciation, honorifics, natural phrasing, and idioms — plus your full script. Every weakness is tracked, and spaced repetition (SRS) brings it back right before you would forget.
Real Korean pronunciation scoring. Get scored on your pronunciation, compare your recording to a native model, and practice by shadowing until you sound natural.
BUILT FOR EVERY LEARNER
Starts in your language. Ksori opens in your phone's language automatically — English, Spanish, Thai, Vietnamese, Indonesian, and more.
Learn Korean from zero. An optional Hangul (Korean alphabet) module lets you read and pronounce Korean letters if you are a complete beginner.
Korean survival phrases. Need the right words fast — at the hospital, an office, immigration, or a taxi? Find the situation, read it in your own language, tap to flip to Korean, and practice speaking it.
FOR K-CULTURE FANS AND FUTURE KOREA RESIDENTS
Whether you love K-pop and K-dramas, you are planning to study or work in Korea, or you already live there, Ksori builds the Korean conversation skills you actually use — spoken out loud, every day.
