AI Checker (AIチェッカー) is a free, no-signup Japanese text analysis tool. It uses statistical rules to surface writing features such as length patterns, stock phrases, sentence-ending habits, and repeated phrases, and can optionally add a DeepSeek-assisted style review. It does not claim to determine whether a text was written by AI.
