QuillBot

QuillBot rewrites and paraphrases text using AI, with selectable modes including Standard, Formal, Creative, and Academic — adjusting the output register for different contexts. It integrates with Google Docs, Word, and browsers through extensions, making it available during the writing process without separate application switching.

Students, ESL writers, and content producers use QuillBot to improve how they express existing ideas — rewriting drafts for clarity, changing formal register, or finding alternative phrasing for repeated terms. The summarizer and grammar checker extend its utility beyond paraphrasing alone.

QuillBot is a refinement tool, not a generation tool — it rewrites what you give it, not creates new content from scratch. Aggressive rewriting in creative mode can drift from the original meaning; reviewing outputs for accuracy is important before using them in high-stakes writing. The free tier provides limited paraphrase length; premium removes restrictions.
