Our review

QuillBot made its name with the Paraphraser: multiple rewrite modes plus a grammar checker, summarizer, plagiarism checker and citation generator cover students' and writers' most frequent needs, and the free tier handles light use.

Long-form creative writing isn't its game, and the free plan caps words and modes. But for making a passage smoother, changing its tone or avoiding repetitive phrasing, QuillBot is still the handiest knife in the drawer.
