How Originality.ai works

One of the two detectors (alongside GPTZero) that most humanizer tools explicitly test their output against. Originality.ai is pay-as-you-go credits or $14.95/mo for the pro plan.

How WriteHuman AI performs against it

One of the more heavily marketed student-focused tools, though third-party detector testing found inconsistent results even on the paid tier.

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, WriteHuman AI's core strength — retry option lets you regenerate a rewrite if the first pass reads oddly — matters more than any single detector's score. Students who want an accessible entry point but should verify output with a second detector before submitting anything.
