✦ 关于 AI Checker（AIチェッカー）

AI Checker (AIチェッカー) is a free, no-signup Japanese text-style analysis tool. It looks at length patterns, stock phrases, sentence endings, and phrase repetition, and can optionally use DeepSeek to help review writing style. It does not claim to determine whether a text was written by AI. The basic style check is free without signup; detailed reports are optional paid Basic/Pro plans.
