About GPTZero
GPTZero uses perplexity and burstiness as its primary signals, with a secondary neural classifier. It's available as a free tool and integrated into many school and editorial platforms.
GPTZero is one of the most widely used AI detectors, measuring text perplexity and burstiness to identify AI-generated content. AI-written text tends to have uniformly low perplexity (predictable word choices) and low burstiness (uniform sentence lengths). AI2Human introduces natural variation at the sentence and paragraph level, which is how it reduces the specific statistical signals GPTZero measures — without any guarantee of a specific outcome on a proprietary, third-party tool.
How to Write Naturally for GPTZero with AI2Human
Three steps to make your text read more naturally to GPTZero.
Paste your AI-generated draft
Copy text from any AI writing tool — ChatGPT, Claude, Gemini, Jasper, Copy.ai. Paste it into AI2Human's text box.
Select Heavy mode
Heavy mode maximizes sentence structure variation and vocabulary diversity — the two primary signals GPTZero measures. This helps the text read more naturally and reduces the statistical patterns associated with AI writing.
Review the result
Read through the rewritten text to confirm your meaning is intact. If you check it with GPTZero, treat the result as one signal about writing style, not a verdict — no tool can guarantee a specific score on a proprietary system.

GPTZero — Frequently Asked Questions
How does GPTZero detect AI writing?
GPTZero measures perplexity (how predictable each word is given the surrounding context) and burstiness (how varied sentence lengths are across the text). AI models tend to produce low-perplexity, low-burstiness text. AI2Human increases both to better match natural human writing statistics.
Does AI2Human guarantee a specific GPTZero score?
No. GPTZero's model is proprietary and changes without notice, so no tool can promise a fixed score. Heavy mode consistently produces more natural, varied writing that tends to read differently to GPTZero's statistical checks — but any single detector result should be treated as one weak signal, not a verdict.
Does AI2Human work on the latest GPTZero model?
AI2Human's rewriting approach isn't tied to a specific GPTZero version. We periodically review our output against current public detectors to keep the structural rewriting effective, but detector vendors don't publish update schedules, so we can't promise a fixed re-verification timeline.
Is GPTZero used by schools and universities?
Yes. GPTZero is used by educators at thousands of schools and universities worldwide. It's also embedded in some learning management systems and editorial platforms.
Will GPTZero always read AI2Human's output as human-written?
We can't promise that, and no honest tool can. AI2Human's Heavy mode substantially increases the natural variation in sentence structure and word choice that GPTZero measures. Always check your institution's or employer's policy on AI assistance before you submit anything — that policy takes precedence over any writing tool.
