Pay by rewritten words — not by washing the whole file.

Whole-document “humanizers” charge you to touch paragraphs the detector never flagged. HumanPen starts from the report: only continuous prose that is highlighted enters the rewrite bill.

Layout survival matters for theses and grant drafts: headings, captions, and page breaks should come back. We optimize for that workflow and refuse guarantee-pass marketing.

Try the loop at https://humanpen.net when your next step is import → flagged-only → recheck.
