What is QuillBot?

QuillBot is an AI-powered paraphrasing tool that rewrites text while preserving meaning, making it the go-to platform for students, researchers, and content creators who need to rephrase content. The tool offers seven distinct rewriting modes — Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten — each optimizing for a different outcome.

Users can control the level of change on a slider from minimal tweaks to complete rewrites. Beyond paraphrasing, QuillBot includes a grammar checker, summarizer, citation generator, and plagiarism checker, creating a comprehensive writing toolkit. Its summarizer can condense long articles into key bullet points or a coherent paragraph, which is valuable for research workflows.

QuillBot integrates directly into Google Docs and Microsoft Word via extensions, enabling in-place rewriting without switching tools. The platform supports multiple languages for paraphrasing, though English produces the highest quality results.

QuillBot was acquired by Course Hero in 2023, which expanded its academic feature set including the citation generator that supports APA, MLA, Chicago, and other formats automatically.
