About the AI Content Detector
This AI content detector estimates whether a piece of writing was likely produced by a human or by an AI model. It looks at signals like repetitive phrasing, sentence-length variety, generic transitions and specificity of detail, then gives a verdict with a confidence level and bullet-point reasoning.
No detector is perfect. Short passages are harder to judge, and heavy human editing can mask AI origins. Use the reasoning provided, not just the verdict, and treat the result as one signal among others.
AI Content Detector FAQs
It gives an estimate with reasoning, not proof. Short texts are harder to judge, and skilled human editing can fool any detector. Treat the verdict as a signal, not a final judgment.
