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 QuillBot Humanizer performs against it
Consistently ranks behind dedicated humanizers on Turnitin and GPTZero in third-party comparisons because it leans on synonym substitution rather than deep sentence restructuring.
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, QuillBot Humanizer's core strength — bundled ai detector, grammar checker, and paraphraser in one subscription — matters more than any single detector's score. People who already pay for QuillBot's grammar/paraphrase suite and want a decent bonus feature, not a dedicated bypass tool.
