1Ryota here. I write in both English and Japanese, and every humanizer I tried mangled Japanese - particles dropped, honorifics flattened, meaning shifted. So I built Suikou AI with morphology-aware prompt chains for JP and KR instead of treating them as translated English. Undetectable AI and QuillBot are fine for English, but if you work in Japanese or Korean you will feel the difference immediately. Feedback very welcome.
