Good questions.
Clear answers.

HumanDoc humanizes AI-generated text inside Word documents. It rewrites robotic or formulaic wording into more natural prose for research papers, class homework essays, proposals, reports and other long-form writing.

Upload a draft made with ChatGPT, Claude, Gemini or another AI writing tool. You receive a clean .docx, tracked changes and a meaning-check report.

HumanDoc reports a 95% detector-pass success rate. This is HumanDoc’s reported rate, not an independently verified benchmark. Results vary by document and detector, and no individual document or score is guaranteed.

HumanDoc does not run an AI detector. The orange and green score cards on the Examples page are explicitly illustrative, not actual scans of the sample. HumanDoc is not affiliated with or endorsed by GPTZero.

Yes. HumanDoc is designed for AI-assisted research papers, manuscripts, class homework essays and proposals, including documents that already contain formatting and references. Review the changes, confirm the facts and follow the writing and disclosure requirements for your work.

One Word document (.docx) up to 25 MB. Research manuscripts, theses, essays, reports, proposals and book chapters are welcome. PDFs, older .doc files and macro-enabled documents aren’t supported.

We count source words in the prose we actually process. Preserved headings, references, captions, tables, front matter and other excluded paragraphs don’t count. Your quote shows the eligible words before you start; failed jobs aren’t charged.

The daily free allowance resets at 00:00 UTC.

The rewrite is placed back into the original Word document, retaining its styles and structure. Technical terms, measurements, quotations and citation text are protected where identified.

Paragraphs containing live fields, including EndNote or Zotero citation fields, as well as hyperlinks, comments, equations, drawings or content controls stay unchanged. If you want those paragraphs rewritten, convert citation fields to plain text in a copy first.

Text length can change pagination. Check the final Word document before sharing it.

Yes. A separate review compares the rewrite with the source and flags significant meaning changes with yellow highlights. Omissions are listed in the Issues tab and report.

The review cannot guarantee that it finds every problem. Tracked changes let you inspect, accept or reject edits in Word. You remain responsible for reviewing the result.

Uploaded documents and results are available for 24 hours after completion, or 24 hours after upload if you never start. They are then removed by the next automatic hourly cleanup. Download your files while they’re available. Job counts, charges and timestamps are retained for 90 days for support and accounting.

Your document is processed on our servers and by contracted third-party AI processors to produce your result. Documents are not used for training. See our Privacy Policy for the details.

Allow minutes rather than seconds. Time depends on your document’s length, the review steps and the queue. Your job page shows its stage, elapsed time and queue position when available. You can return to that link on the same device, or while signed in to the same account.

Failed jobs release their reserved words. Unused purchased word balance is refundable on request within 14 days of purchase. Contact support@humandoc.app with your purchase details. Read our Refund Policy.
