Humanize AI text and check how human it reads
Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
An undetectable AI humanizer with a built-in multi-detector checker
Paste AI-written text and uPass rewrites it with vocabulary and sentence structures that read like a person wrote it, rather than simple synonym swapping.
Check a passage against several popular detectors in a single run instead of submitting it to each service separately, and see where your text stands.
Select Basic, Advanced or Aggressive depending on how much restructuring the text needs while keeping the meaning intact.
The rewriter generates varied phrasing designed to keep output free of matches flagged by plagiarism checkers as well as AI detectors.
