Korean AI Humanizer — Built for 한국어 Morphology

Korean AI text gets flagged by detectors for unnaturally uniform 조사 patterns and textbook 어미 rhythm. Suikou's Korean profile is tuned to the morphological signals that distinguish human Korean from GPT output.

Last updated:

Why Korean needs morphological awareness

Korean has agglutinative morphology — particles (조사: 은/는, 이/가, 을/를) attach to nouns and verb endings (어미: -다, -니다, -아요, -습니다) inflect heavily by context. AI-generated Korean tends to over-uniform these morphological signals, especially the formal -습니다/-입니다 endings. Suikou's Korean profile varies endings appropriately by register, naturalizes particle distribution, and balances 한자어 vs 고유어 ratio for the target genre.
