AI Detection You Can Trust

Helping teachers, schools, and universities verify whether written work is genuinely human-authored.

How does Exolio detect AI-written text?

Our system has been trained on thousands of examples of both human writing and AI-generated text (from tools like ChatGPT). When you paste text in, it looks for patterns — word choice, sentence structure, writing style — typical of AI versus human authors.

The result is a percentage score showing how likely the text is to be human-written or AI-generated — like a "confidence meter".

The Quick AI Check below is a fast automated scan. For a thorough, expert-level review (e.g. before academic decisions), our Document Upload (subscribers) goes much deeper:

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.
