Increases Perplexity
AI text is too predictable. We introduce less expected word choices that raise the perplexity score.

FAQ
How does GPTZero detect AI text?
GPTZero measures perplexity (how predictable the word choices are) and burstiness (how much sentence length varies). AI text scores low on both. Human text is high on both.
Does EssayCloak beat GPTZero every time?
Our humanized output consistently scores 90%+ human on GPTZero. No tool is 100%, but we achieve the highest rates available.
