How does Exolio detect AI-written text?
Our system has studied thousands of examples of real human writing and AI-generated text. It has learned to spot the difference based on patterns in how words and sentences are put together. When you paste text in, it compares those patterns and tells you how likely it is that the text was written by a person or by AI.
No AI detection tool is 100% accurate. Our scores are a helpful signal, not a final verdict. We recommend the Quick AI Check as a starting point, and Document Upload for situations where you need more confidence.
