Estimate whether text was AI-generated using probability scores and sentence-level signals, with checks up to 10,000 words.
Clever AI Detector is a free online tool designed to estimate the probability that a given text was generated by artificial intelligence. It analyzes statistical signals such as word predictability, rhythm consistency, and common AI phrasing to provide a probability score for the entire text and at a sentence level. The tool aims to offer transparency about its confidence in its results, indicating when it is uncertain.
Clever AI Detector is 100% free to use, with no ads or paywall. There are no paid plans or subscription tiers mentioned.
Clever AI Detector is a free AI checker that approximates the likelihood of text being AI-generated by analyzing statistical signals like word predictability, rhythm consistency, and common AI phrasing. It scores each sentence separately and provides an overall score from 0-100.
No AI detector is 100% accurate. Clever AI Detector provides a probability score and sentence-level signals, and it is transparent about its confidence levels. Users are advised to treat the score as one piece of information rather than a definitive verdict.
There is no catch. The tool is offered for free with unlimited use, no ads, and no paywall. CleverFiles, the company behind it, often releases products for free initially.
Yes. The detector identifies statistical patterns common in AI-generated text, regardless of the specific AI tool used, including ChatGPT, Gemini, Claude, and others.
A false positive occurs when human writing is incorrectly flagged as AI-generated. This can happen more often with formal, heavily edited, or non-native texts due to their uniformity. The tool provides probabilities and signals to help assess these cases.
Paste your text into the input box and click "Check for AI". The results, including an AI probability score and sentence-level signals, will appear shortly.
The score represents the probability that the text was generated by AI. A high score indicates that the text's statistical profile closely resembles that of AI writing.
Articles, blog posts, emails, product descriptions, reports, and marketing copy in English, with a length between 80 and 10,000 words, can be checked.
An AI detector identifies AI-generated text, while an AI humanizer modifies AI text to sound more natural. Clever AI Detector and Clever AI Humanizer work together on the same page.
Checks are performed to calculate scores. Signed-in users have the option to maintain a history of their checks. Data processing is detailed in the Privacy Policy.
Users are responsible for decisions based on the detection results. The score is a probabilistic signal, not a definitive verdict, and should not be the sole basis for actions affecting individuals. The Terms of Service outline responsibilities and limitations.
Yes, Clever AI Detector is a free online AI checker that requires no sign-up, ads, or paywall for basic use. Account creation is optional and enables check history.
Yes, the tool functions as a detector for text generated by ChatGPT and other AI models by identifying common statistical patterns.
Transparency about uncertainty, reporting probabilities, providing sentence-level evidence, and admitting when confidence is low are characteristics of accurate AI detection software. Clever AI Detector follows this approach.
Users choose it because it is trained on recent LLMs and extensive datasets, is free to use, provides sentence-level signals, and includes a confidence level.
