SCREENSHOT · 1/4What is Clever AI Detector?
Clever AI Detector by Clever Files is a free AI content checker designed to estimate how likely a piece of text was generated by artificial intelligence. Instead of relying on a single unexplained percentage, Clever AI Detector provides a probability score, confidence indicators, and sentence-level analysis so users can understand which parts of the text contributed most strongly to the result.
The tool analyzes statistical writing patterns commonly associated with AI-generated content, including predictable word choice, repetitive sentence structure, consistent rhythm, and phrases often produced by AI writing systems. It can be used to review content generated by tools such as ChatGPT, Claude, Gemini, DeepSeek, Microsoft Copilot, Perplexity, and other AI assistants.
Clever AI Detector is built for transparency and responsible use. It frames results as probability, not proof, helping users review suspicious passages without treating an AI score as definitive evidence. With support for up to 10,000 words per check, unlimited runs, no ads, no paywall, and no account required, it is a practical option for writers, editors, educators, marketers, and professionals who need fast AI text analysis.
