About this tool

QuillBot is a writing utility best known for its AI paraphraser, which rewords sentences and paragraphs across multiple style modes such as Standard, Fluency, Formal, Simple, Creative and Shorten. The platform has grown into a wider suite that includes a grammar checker, summarizer, translator, citation generator, plagiarism checker, AI detector and an AI chat assistant that can answer questions and draft text. A Word and Google Docs add-in, a Chrome extension and mobile apps put the same tools inside everyday writing workflows. QuillBot is heavily used by students, ESL writers, researchers and content marketers who want to rephrase or polish existing text rather than write from scratch. Premium plans unlock unlimited paraphrasing length, more style modes and higher word limits on the other tools.
