About this tool

HumanPen is a document-level AI humanizer that rewrites AI-generated text in DOCX, PPTX, and TXT files while preserving layout, citations, and formatting. It lets users target flagged passages from Turnitin or iThenticate reports, paying only for rewritten words, and also offers condensing, citation fixing, and translation tools. An API and agent integration make it easy to plug into automated workflows.
