Clever AI Detector analyzes writing through statistical indicators such as wording predictability, sentence rhythm, and phrases associated with AI-generated text. It scores each sentence separately, combines those signals into an overall AI probability score, and displays a confidence level to show how certain the result is. Users can paste text or upload a file, check up to 10,000 words per run, and repeat checks without limits. Results include a verdict, highlighted sentences, sentence counts, and an option to copy the report. Signed-in users can save and revisit check history, while guests can use the detector without registration. The service focuses on English text and clearly presents results as probability rather than proof, acknowledging possible false positives and uncertainty.
