QuillBot

QuillBot started as a sophisticated paraphrasing tool and has expanded into a full suite with a summarizer, grammar checker, citation generator, and plagiarism detector. It remains a go-to for students and academics needing to rephrase research, summarize papers, and ensure originality. The freemium model is generous, and the core paraphrasing engine offers multiple modes (Fluency, Formal, Creative). Its rank is built on reliability for text transformation and its strong utility in the education and research sectors.
