Rewriting involves taking your text’s meaning and recreating the actual sentences from scratch. If we were to rewrite this sentence, you probably wouldn’t see a lot of the same words. Paraphrasing is pretty similar. It involves taking existing text and putting it into new words, though changes may be less extreme than with rewriting.
Humanizing keeps your text largely the same but changes things like sentence structure and length, as well as word choice, to remove those distinct AI “tells.”
