AI paraphrasing, grammar checking, and writing assistant for students
What is Quillbot?
Quillbot is an AI-powered writing toolkit popular with students, researchers, and professionals. Its core paraphraser rewrites text in multiple modes — Standard, Fluency, Formal, Academic, Simple, Creative, and Expand/Shorten — giving users fine-grained control over tone and style while preserving meaning.
Beyond paraphrasing, Quillbot bundles a grammar checker, summarizer, citation generator, plagiarism checker, and AI content detector into one platform. The summarizer condenses long texts into key bullet points or paragraph form. The citation generator supports APA, MLA, Chicago, and other formats. The plagiarism checker scans against billions of web pages and academic databases.
Quillbot integrates with Chrome, Word, and macOS, making it accessible directly within writing workflows. The free tier allows paraphrasing up to 125 words at a time with Standard and Fluency modes. Premium unlocks unlimited paraphrasing length, all writing modes, advanced grammar rewrites, and the plagiarism checker.
Acquired by Course Hero, Quillbot has grown to over 35 million monthly visitors, making it one of the most-used writing tools in education.
