Suikou AI

Suikou AI is an editing workspace for turning stiff AI-generated drafts into more natural writing. Its Japanese-first workflow focuses on details such as verb endings, particles, and the balance of kanji and kana, while also supporting other languages. Choose casual, academic, or business mode to match the intended voice. Suikou AI is designed to preserve citations and important domain terms while you review and revise the result. The free plan includes up to 500 words per day.
