It cut my editing pass in half, and the rewrite still sounds like something I would have written myself.
Fast, clean output every time. I have not had a flagged draft yet.
The awkward phrasing that gives AI drafts away is simply gone, and the meaning of the original survives.
Output quality is the real surprise here. It reads far more naturally than anything else we trialled.
We tested six rewriting tools across a month of client work. This was the only one we kept.
Rankings held and the copy finally sounds human. That combination is rare.
Undetectable results
Detectors look for patterns that show up constantly in machine writing: predictable phrasing, uniform sentence length, vocabulary with no human variation. StealthGPT restructures sentences, rewords stock expressions and restores the small irregularities of real writing without changing what you meant.
The output reads more naturally, keeps its readability, and holds up when evaluated by detection tools and by people.
Sample run: 30 passages humanized, 0 flagged across five leading detectors.
