QuillBot is an AI writing assistant centered on paraphrasing, helping users rewrite sentences and paragraphs in different tones while keeping the original meaning intact. Formed in 2017 and based in Chicago, Illinois, QuillBot was acquired in 2021 by Learneo (formerly Course Hero), and continues to operate under its own brand as one of Learneo's core products.
Beyond paraphrasing, QuillBot has expanded into a full writing suite that includes grammar checking, plagiarism detection, text summarization, citation generation and multi-language translation, positioning it as a one-stop tool for students, non-native English speakers, and professional writers who need to refine and polish text quickly.
QuillBot's paraphrasing tool offers multiple modes, including Standard, Fluency, Formal, Academic, Simple, Creative, Expand and Shorten, so users can adapt output for casual writing, academic papers, or professional communication. The grammar checker flags punctuation, word choice and sentence structure issues alongside the paraphraser.
Additional tools include a plagiarism checker that scans against billions of web and academic sources, an AI summarizer for condensing long documents, a citation generator supporting APA, MLA and Chicago styles, and QuillBot Translate, which supports more than 50 languages. A Chrome extension, Word add-in, and mobile apps bring these tools into the environments users already write in.
QuillBot uses a freemium model: the Free plan limits paraphrasing to 125 words at a time and includes basic grammar checking, while Premium removes the word limit and adds advanced grammar suggestions, the plagiarism checker, translation tools and priority support.
Premium costs $19.95/month billed monthly, $39.95 per quarter (about $13.31/month), or $99.95 per year (about $8.33/month), the best value at roughly 58 percent savings versus monthly billing. A Team plan for 2 to 10 seats starts around $7.50 per user per month billed annually, and verified students receive discounted Premium access.
