QuillBot

What QuillBot does

QuillBot is best known for its paraphraser, which rewrites a passage at different strength settings while keeping the meaning, and for a summariser that condenses long text into key points or a short paragraph. Around those it has assembled a grammar checker, a citation generator, a plagiarism check, a translator and a browser extension, along with a document editor that combines them. Its audience is largely academic: students rephrasing notes, non-native speakers clarifying their own sentences, and researchers compressing sources. It suits anyone who works with existing text more than with blank pages. Two limitations deserve stating plainly. Paraphrasing someone else's work does not make it your own, and institutions increasingly treat heavy use as academic misconduct. Technically, the higher rewrite settings frequently distort meaning or produce awkward phrasing, so output needs reading against the source rather than trusted.

How to use it

Go to quillbot.com and use the paraphraser without an account to see how it behaves; signing up raises word limits and unlocks the stronger modes. Paste a paragraph rather than a whole document, because quality drops over long passages and you lose the ability to check meaning carefully. Choose a mode, start with the mildest, and use the synonym slider sparingly since pushing it high is what produces unnatural phrasing. Words you want preserved can be frozen so technical terms survive the rewrite, which is the setting most people miss. The summariser works better on structured source material than on transcripts. If you are writing academic work, use the citation generator to keep references attached to the original source and treat paraphrasing as a drafting aid on your own sentences, not a way to reuse someone else's. Free accounts limit word count per operation and restrict the advanced modes; the premium tier removes those caps.
