AI-assisted drafts
What the humanizer fixes in AI-assisted drafts
AI drafts often repeat the same generic words in a flat, monotonous sentence rhythm. The humanizer rewrites them into natural, human writing style.
Generic Phrasing
AI drafts repeat the same mechanical openings and linking words. The humanizer varies them, while preserving your intended meaning.
Monotonous rhythm
When every sentence has the same length, a paper sounds stiff. The humanizer varies sentence lengths for a more active, bursty rhythm.
AI-flavored wording
Commonly preferred AI words make research writing sound robotic. The humanizer replaces them with concise wording actually used by humans.

FAQs
Questions before you start
What does the AI humanizer change in my text?
It changes the wording and the sentence rhythm. Repetitive phrasing and stiff sentences are rewritten into natural academic prose, and your meaning, key terms and citations are preserved. You see every edit in the Diff view.
What is ULTRA?
ULTRA is the sixth and highest intensity setting and our deepest rewrite, for drafts that need the most work. Readability and grammar are slightly lower than at the other settings, so revise the output before you submit it. ULTRA comes with the Academic Plus plan.
Does it work for writers using English as a second language?

Yes, with Academic Plus. The Doc Humanizer takes a .docx file of up to 15,000 words and processes it in one round. Headings, lists, tables, equations, footnotes and the reference list are preserved.
