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 Walter Writes AI performs against it

Cited in multiple 2026 comparisons as one of the more reliable mid-tier tools against GPTZero.

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?

Users who process the same type of document repeatedly and want predictable results every time.
