HumanPen is a document-level AI humanizer for DOCX and PPTX. Import a detection report to rewrite flagged passages while keeping layout, citations, numbers and formulas intact. It is built for writers and educators who want clearer guidance on what to revise.

Writers kept getting vague AI-detector percentages with no guidance on what the score meant or how to revise carefully. We built HumanPen so document structure stays intact while phrasing is rebuilt, without claiming any detector outcome.
