QuillBot
AI Paraphraser and Writing Suite
What is QuillBot?
QuillBot is the most widely-used AI paraphrasing tool, with over 50 million users relying on its rewriting engine. While most AI writers generate from scratch, QuillBot specializes in transforming existing text into clearer, more polished prose. The QuillBot paraphraser offers seven modes including Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten, each tuned for a specific rewriting goal. Beyond paraphrasing, QuillBot bundles a grammar checker, summarizer, citation generator, plagiarism checker, and AI-powered translator. Students, researchers, and content writers use QuillBot to elevate prose, escape repetitive phrasing, and meet word counts. QuillBot's browser extension and Word add-in bring rewriting into every writing context.
