Pick QuillBot Free if…
you rephrase a sentence or two at a time and can live with 125-word chunks.
QuillBot Free caps paraphrasing at 125 words and the humanizer at 6 uses a day, which means pasting text in small chunks. Premium removes those limits and adds AI chat and a plagiarism checker.
Free works for rephrasing the odd sentence or short paragraph. Premium ($19.95/mo billed monthly, much less billed annually) is for students and writers paraphrasing whole essays or checking for plagiarism.

Premium is $19.95/mo on monthly billing and much cheaper per month billed annually. Free costs nothing.
Paraphrase more than 125 words at a time, use the humanizer more than 6 times a day, use AI chat, or run plagiarism checks.
