WriteHuman and Quillify both solve the same immediate problem: AI-generated text that flags on Turnitin, GPTZero, or Originality.ai. Both rewrite the text using a language model. Both offer a free tier. The difference is scope. WriteHuman is a focused, single-function tool. Quillify is built around a broader writing workflow that includes citation tools, academic formatting, and professional writing modes.

Where WriteHuman Is Better
Simplicity
WriteHuman is a clean, single-purpose tool. Paste text, get humanized text. No workflow to learn. If humanization is all you need and you want to do it in 30 seconds, WriteHuman delivers that. Quillify has more features, which means more to learn.
Price at the entry level
WriteHuman's basic plan is priced lower than Quillify's Student plan. For users who only need humanization with no academic or professional extras, WriteHuman costs less per month.
Where Quillify Is Better
Sentence-level scoring — you can verify the result
Quillify shows you a GPT-2 perplexity score for every sentence before and after humanization. WriteHuman gives you humanized output with no visibility into which parts improved and which didn't. For high-stakes submissions, knowing the score dropped from 82% to 9% sentence by sentence matters.
Deep mode for the hardest cases
When a single humanization pass isn't enough, Quillify's Deep mode runs three passes: pattern variation, register calibration, and a surgical final pass on high-scoring sentences. WriteHuman has one pass.
Everything else in the workflow
For students: after humanizing, you still need to format citations, find references, and export a Word document. Quillify handles all of that in the same tool. For professionals: Quillify's Executive Email, Business Report, and Client Proposal modes apply different tone registers — a consulting report and a cold outreach email need different treatment.
