About Suikou AI
Suikou AI is a global AI writing naturalizer (humanizer) with a built-in AI text detector. Paste AI-generated text and it rewrites it into natural, human-sounding prose in three registers — casual, academic, and business — in seconds. The detector scores any text for AI probability, perplexity, and burstiness so you know how "machine" your writing reads. Built by a Kyoto NLP researcher, Suikou AI's Japanese support is best-in-class: a morphology-aware engine that generic humanizers can't match, while working great across English and other languages too. Free tier covers 500 words/day; paid plans start at $9.99/mo, with a 50% student discount via .edu email verification.
