How Originality.ai processes Grammarly-edited text

Originality.ai works via sentence-level classifier confidence tuned for web content. Grammarly-Edited Text — human or AI prose after grammar-tool polishing — is judged on that layer alone: sentence rhythm, predictability, and structural pattern. Ideas, truth, and effort are invisible to it.

For publishers and agencies, the practical takeaway: Grammarly-edited text triggers attention when its statistical texture looks generated. Human Or AI Prose After Grammar-Tool Polishing — which is why some cases sail through and near-identical ones get flagged.

What actually changes the outcome

Three levers: varied sentence rhythm (the layer sentence-level classifier confidence tuned… measures), concrete specifics no model invents, and compliance with whatever policy governs the Grammarly-edited text. A Neonhumanizer pass automates the first; you own the other two.

If your Grammarly-edited text needs to read human, work the texture: run a meaning-safe humanizing pass, then re-read for the one detail per paragraph only you could know. That combination beats every synonym-swap trick, because it changes what Originality.ai measures instead of decorating it.

False positives, policy, and the honest frame

Fully human writing gets flagged too — formal register mimics machine texture. And where a policy governs the Grammarly-edited text, the policy outranks any score in both directions. Keep drafting evidence; it settles disputes faster than rescans.

The ethics line is simple: where AI assistance is allowed for this kind of Grammarly-edited text, humanizing is a legitimate style edit. Where it's banned, no answer on this page changes that. Own the disclosure question before optimizing any score.
