AI paraphrasing and summarization for better writing
About QuillBot
QuillBot is an AI writing tool built around a highly capable paraphrasing engine that can rewrite text across seven distinct modes — Standard, Fluency, Formal, Academic, Simple, Creative, and Expand or Shorten. This range of modes makes it adaptable to a wide variety of writing contexts, from academic papers and professional emails to casual blog posts and social media content. Beyond paraphrasing, QuillBot includes a summarizer for condensing long articles and documents, a grammar checker, a plagiarism detector, and a citation generator — making it a comprehensive writing toolkit particularly suited to students and researchers. Its Google Docs and Microsoft Word extensions bring all features directly into the document editor without requiring users to switch between tools.
