AI writing that still sounds human — humanizer & detector for students and writers.
HumanPen is a document‑level AI humanizer that rewrites AI‑generated text while preserving the original layout, citations, numbers, formulas and terminology. Users can upload DOCX, PPTX or TXT files of any length, then either select passages manually or import a Turnitin or iThenticate detection report to target only flagged sections. Rewrites are charged per word actually changed, with 100 free credits for new users and free rewrites until the AI similarity score drops below 20%. The tool returns the file with its original styling intact and also offers an API that can be called with a single line of code for integration into custom workflows.
