Paste any text and instantly check the likelihood it was written by AI like ChatGPT, Claude, or Gemini.
Our AI Detector tool analyzes text and estimates the likelihood that it was generated by an AI language model such as ChatGPT, Claude, or Gemini, versus written by a human. It looks at patterns like sentence length variation, vocabulary choices, structural predictability, and natural human idiosyncrasies to provide a probability score along with a plain-language explanation.
This tool is useful for educators, editors, content managers, and writers who want a quick estimate of whether a piece of text may be AI-generated. Keep in mind that AI detection is inherently an estimate, not a definitive verdict. No detection tool, including this one, can guarantee 100% accuracy, so results should be used as a helpful guide rather than absolute proof.
The tool provides an estimate based on writing patterns and is not 100% accurate. Results should be used as a guide rather than a definitive judgment.
Yes, our AI Detector is completely free to use with no login required.
The probability score reflects how likely the text appears to be AI-generated based on writing patterns, with a verdict of Likely Human-Written, Possibly AI-Generated, or Likely AI-Generated.
We recommend against using AI detection results as the sole basis for any disciplinary or editorial decision, given the inherent limitations of AI detection technology.
