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 GPTinf performs against it
Marketed as being trained directly against detector models rather than general paraphrasing, which independent testers cite as the reason its scores hold up on technical text.
Bypass-rate figures come from third-party testing at a point in time. Detector models update regularly, and results vary by source text, topic, and length — treat any specific percentage as a snapshot, not a guarantee.
Should you rely on this combination?
If your goal is genuinely natural-sounding writing rather than evading a specific check, GPTinf's core strength — eight distinct rewriting modes (academic, formal, informal, creative, simple, standard, expand, shorten) — matters more than any single detector's score. Writers who want granular control over tone and which specific sentences get rewritten.
