QuillBot is an AI writing tool focused on paraphrasing, summarisation and writing improvement. Its core paraphrasing engine can rewrite text in multiple modes — Standard, Fluency, Formal, Academic, Simple, Creative and Expand — giving users fine-grained control over how their content is transformed.
The platform has expanded significantly beyond paraphrasing to include a grammar checker, plagiarism checker, summariser, citation generator, translation tool and full AI writing assistant. This suite of tools makes it particularly popular with students, academics and non-native English speakers who need help refining their writing.
With over 35 million users worldwide, QuillBot has become one of the most widely used AI writing tools. The free plan is genuinely useful with 125 words per paraphrase, and the Premium plan unlocks unlimited paraphrasing, all rewriting modes and the full tool suite.

QuillBot occupies a unique niche — it is not trying to generate new content from scratch, but to help you improve what you have already written. For students and academics this is particularly valuable, and the citation generator is a genuinely useful feature that competitors don't offer. The 20% recurring affiliate commission is solid, and the large user base (35M+) makes it an easy tool to recommend credibly. A worthwhile listing for AI Tool Bible.
