About QuillBot

QuillBot has grown into one of the most comprehensive free writing toolkits on the internet, serving over 35 million users globally. Its flagship paraphrasing tool offers multiple rewriting modes — from Standard and Fluency to Creative and Formal — giving users precise control over the final output. The integrated grammar checker catches errors in real time, while the plagiarism checker scans against billions of web pages to ensure originality. Students particularly benefit from the citation generator, which supports APA, MLA, Chicago, and other major formats automatically. A built-in summarizer condenses long documents into key points, and the Co-Writer combines all tools in one workspace. MS Word add-in and Chrome extension ensure QuillBot fits naturally into existing workflows. Premium users unlock unlimited paraphrasing length, faster processing, and access to advanced writing modes.
