How GPTZero works
The detector most frequently named as the benchmark that humanizer tools market their bypass rates against. GPTZero is free tier available; paid educator and enterprise plans scale by document volume.
How StealthGPT performs against it
Positioned and marketed specifically around Turnitin's originality algorithm rather than general-purpose detectors.
Should you rely on this combination?
If your goal is genuinely natural-sounding writing rather than evading a specific check, StealthGPT's core strength — generates and rewrites in one pass, so you can skip a separate ai writer — matters more than any single detector's score. Long-form academic or research writing where sentence-level restructuring matters more than speed.
