What is QuillBot?
QuillBot has become the dominant AI paraphrasing tool in academic and student writing, used by over 35 million people. Its core paraphraser offers seven modes — Standard, Fluency, Formal, Academic, Simple, Creative, and Shorten — allowing writers to control how much the AI rewrites the original while preserving meaning. The Co-Writer combines the paraphraser, summarizer, and citation tools in a single editing environment. The Summarizer condenses long articles or documents into key points. The Grammar Checker identifies errors beyond what basic spell-checkers catch. The Plagiarism Detector checks content against 100M+ web pages. The Citation Generator formats citations in APA, MLA, Chicago, and other styles. This bundled tool suite at $9.95/mo makes QuillBot exceptional value for students managing multiple academic writing needs in one subscription.

Use Cases
Academic paraphrasing for research papers
Use QuillBot's Academic mode to paraphrase source material in scholarly language appropriate for research papers — preserving meaning while sufficiently transforming phrasing to avoid plagiarism. The synonym slider controls how much vocabulary changes, and the preserved-words feature protects key terms that shouldn't be altered.
FOR: Students and academics paraphrasing sources for research papers and dissertations
ESL writing fluency improvement
Write in your natural phrasing and use the Fluency mode to improve grammatical correctness and natural English flow. The fluency improvements are more extensive than basic grammar correction — restructuring sentences for idiomatic English rather than just fixing individual errors.
FOR: ESL students and non-native English speakers writing in academic or professional English
Research article summarization
Paste a long academic article or report into the Summarizer and get the key points condensed to a manageable length. Useful for quickly screening whether an article is relevant before reading in full — a significant time saver when reviewing large numbers of potential sources.
FOR: Students, researchers, and academics doing literature screening and source evaluation

QuillBot FAQ
Does QuillBot count as plagiarism?
Paraphrasing with AI is a complex academic integrity question — policies vary by institution. Using QuillBot to understand and rephrase ideas in your own words, then citing the original source, generally complies with academic standards. Using QuillBot to paraphrase source material and pass it off without citation is plagiarism regardless of how much the phrasing changed. Check your institution's specific AI writing policy before using QuillBot in academic submissions.
What is the difference between QuillBot's paraphrasing modes?
Standard makes moderate changes preserving meaning and flow. Fluency prioritizes grammatical correctness and natural English. Formal makes writing more professional and formal. Academic targets scholarly register appropriate for academic writing. Simple makes writing clearer and easier to understand. Creative makes larger, more expressive changes. Shorten reduces word count while preserving core meaning. Choose based on what change you need — most students use Standard or Academic.
Is QuillBot Premium worth it for students?
At $9.95/mo (or $4.17/mo on the annual plan), QuillBot Premium is excellent value for students — it bundles paraphrasing, grammar checking, plagiarism detection, and citation generation that would cost significantly more as separate subscriptions. For students writing regularly with multiple sources, the bundle replaces Grammarly, a plagiarism checker, and a citation manager simultaneously.
