AI Humanizer for GPTZero
Paste your AI-generated text below. GetHumanized increases perplexity and burstiness to human levels — scoring below 5% AI on GPTZero every time.
How It Works
Copy your ChatGPT or AI-written content and paste it into the editor above.
GetHumanized rewrites your text, raising perplexity and burstiness to human-level statistical patterns.
We show you an AI score before and after. Paste the result into GPTZero to confirm — then use it.
Real Results
GPTZero measures perplexity and burstiness — both low in AI text. GetHumanized specifically targets these metrics.
Understanding GPTZero
GPTZero was built by Princeton student Edward Tian and became one of the most widely used AI detectors. It works by measuring two things: perplexity — how predictable the word choices are — and burstiness — how much sentence length and complexity varies throughout the text.
AI-generated text is statistically very "smooth" — low perplexity (predictable words) and low burstiness (similar sentence complexity throughout). Human writing is naturally noisier: we use unusual word choices occasionally, vary our sentence lengths dramatically, and switch registers mid-paragraph.
GetHumanized doesn't just rephrase — it fundamentally restructures the statistics of your text. Aggressive mode uses GPT-4o with custom instructions to introduce exactly the kind of variance that makes text read as genuinely human to GPTZero's classifier.
Why GetHumanized
Intentionally varies word choice to increase GPTZero's perplexity score to human levels.
Varies sentence length and complexity to match the natural rhythm of human writing.
Maximum humanization for stubborn AI patterns that Standard mode doesn't fully fix.
