What is QuillBot?
QuillBot is one of the most widely used writing assistants, built around a paraphraser with multiple rewriting modes including Standard, Fluency, Formal, Academic and Creative. Around it sit a grammar checker, summarizer, citation generator, translator and AI detector, available on the web and through browser extensions that work inside Google Docs and Microsoft Word. The free plan is genuinely usable but has one constraint that shapes everything: paraphrasing is capped at 125 words per run, so reworking a 3,000-word paper means feeding it through in roughly two dozen separate chunks. Free users also get only two of the ten-plus modes and no plagiarism checker. Premium removes the word cap and adds plagiarism checking around 25,000 words a month, at roughly $20 monthly or closer to $50 to $100 a year depending on the plan, with a student discount available.
