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.
