# Leave unflagged sections alone — HumanPen

Charles Li · HumanPen

Most whole-document humanizers rewrite everything. That wastes budget and can scramble paragraphs that never tripped a detector.

HumanPen imports a Turnitin or iThenticate AI report (or lets you mark spans), then rewrites only the flagged continuous prose. Unflagged sections stay yours.

Citations, numbers, and formulas are frozen by design — they are not part of the rewrite bill.
