Structural rewriting, not word swapping
Most paraphrasers swap synonyms. RewriteKit changes sentence architecture — length variation, transition removal, rhythm variation — which actually reduces detection and improves readability.
Three variants, choose the best
Natural, Clean, and Readable are tuned for different purposes. You see all three at once and pick the right one, instead of rerunning a single-output tool.
Detect and humanize in one place
The AI Detector and humanizer are designed to work together. Check your score, humanize flagged sections, check again. The full workflow without switching tools.
40+ languages supported
English, Korean, Japanese, Spanish, French, German, and dozens more. Structural rewriting principles are language-universal.
Frequently Asked Questions
Is RewriteKit completely free?
Yes. All tools — humanizer, detector, rewriter, and all pages — are free with no account required.
How does the humanizer differ from the rewriter?
The humanizer focuses on reducing AI detection signals. The rewriter focuses on writing quality — tone, clarity, and structure. Both improve the text, but for different primary goals.
What languages does RewriteKit support?
40+ languages including English, Korean, Japanese, Spanish, French, German, Portuguese, Italian, and more.
Does RewriteKit store my text?
No. Submitted text is processed and immediately discarded. Nothing is stored.
What is the detect → humanize → detect workflow?
Check your score first with the AI Detector, humanize the flagged sections, then verify again. One or two passes typically reduces a High score to Low.
