About QuillBot
QuillBot started as a paraphrasing tool and has grown into a full writing suite. You can rewrite sentences in different tones, check grammar and spelling, summarize long passages, generate citations and translate.
Its summarizer lets you pick between short key points or a paragraph, and the paraphraser offers modes such as fluent, formal and simple. Browser extensions and a Word add-in bring it into the tools you already use.
QuillBot has a free plan with limits and a Premium plan for unlimited use. Students and professional writers use it every day.
