What is QuillBot?
QuillBot is the leading AI paraphrasing tool, used by millions of students, writers, and professionals to rewrite and improve text. Its core feature is the paraphraser, which offers 7 distinct modes: Standard, Fluency, Formal, Academic, Creative, Expand, and Shorten.
Unlike general AI chatbots, QuillBot is optimized specifically for rewriting existing text rather than generating from scratch. This makes it ideal for students paraphrasing research sources, writers improving sentence flow, and non-native speakers polishing their English.
QuillBot has grown into a full writing toolkit with a grammar checker, plagiarism detector, summarizer, and citation generator — all accessible through a clean, simple interface.
