What is QuillBot?

QuillBot built its name on paraphrasing, and its rewriter remains one of the most used on the web. Multiple modes — Standard, Fluency, Formal, Creative, and more — restyle text for different purposes, with a slider to control how much vocabulary changes. Around that core sit a grammar checker, summarizer, citation generator, plagiarism checker, and co-writer in one account.

The free tier is generous enough for everyday student and professional use, which explains its huge adoption in universities and offices. Premium lifts word limits, unlocks every paraphrasing mode, and adds faster processing. QuillBot now writes and translates in many languages as well. Its AI tools are practical rather than flashy, aimed at polishing and repurposing text you already have.
