QuillBot is a paraphraser, grammar checker, summariser, and citation helper in the browser. Free paraphrases with limits. Premium is commonly about $8.33 a month billed yearly (around $99.95) or about $19.95 month to month, with a separate student checkout that discounts the annual plan (often cited around 25% off). Course Hero Premier Plus sometimes bundles it. Prices compiled 21 September 2026; use quillbot.com/upgrade/student if you have a school email.
Paraphrasing a source you have not understood is still plagiarism. Use it to clean your own sentences, not to launder a PDF.

Run your own draft through it once. If the output is a different paper, you did it wrong. Grammarly is the calmer grammar-only alternative.

The group essay window that never needs a version in the filename.
