Why whole-file processing matters
Pasting paragraph by paragraph into a text-box tool means manually splitting the document, checking each chunk, and stitching it all back - formatting gone, passages missed. Uploading the whole file processes everything in one pass: table of contents, heading levels, and figure numbering never need rebuilding.
Frequently asked questions
Does it work on Claude or Gemini output too?
Yes. The rewrite does not target one vendor; it works on the sentence and rhythm patterns that AI-generated text shares.
Do I paste my ChatGPT output somewhere?
No pasting. Put the content in Word or PowerPoint and upload the whole file.
Will the rewrite distort what I meant?
Meaning comes first: arguments, conclusions, and data stay unchanged - only the expression is restructured. You can also add your own phrasing preferences under extra requirements.
Is the whole document rewritten?
By default, yes; you can also select specific passages, or import a detection report to rewrite only the flagged parts.
How is it billed?
1,000 words costs 100 credits, charged only for the words actually rewritten - and new accounts start with 100 free credits.
