Review-readyWhy ordinary humanizers fail
A rewrite can lower risk while damaging meaning, removing citation cues, changing numbers, or making the final draft harder to use.

The workflow combines detector-risk forecast, meaning preservation, number/entity checks, citation warnings, and ready-to-use word tracking.

Independent forecasts, not official detector scores
Risk forecasts are calibrated estimates. PassLab is independent and is not affiliated with GPTZero, Turnitin, Originality.ai, Copyleaks, or any other detector provider.
