QuillBot

QuillBot is a leading AI paraphrasing tool with grammar checking, summarizing, citation generation, and translation built around rewriting.

Overview

QuillBot’s paraphraser is its core: paste text and choose a mode such as Standard, Fluency, Formal, Academic, or Creative to rewrite at the word, sentence, or paragraph level with a slider for synonym strength. Around that core sit a grammar checker, a summarizer that condenses articles into key points, and a citation generator that formats references in APA, MLA, and Chicago styles. QuillBot integrates with Chrome, Microsoft Word, and Google Docs, and its Flow workspace helps students draft and paraphrase inside one document editor. The paraphraser’s strength is control: users can freeze words that must stay unchanged, which matters for technical terms and quoted material. Flow assembles research, notes, and drafting in one workspace designed around academic assignments. Recent additions of translation and summarization make the tool useful beyond rewriting alone.

Pricing

QuillBot is freemium.

Premium pricing is low relative to competitors, and quarterly and annual options reduce the effective monthly cost.

Who Is It For

QuillBot is for students, academics, and professionals who rewrite text regularly, whether to adjust tone, avoid repetition, or paraphrase sources while keeping meaning intact. ESL writers adjusting tone and avoiding repetition in professional documents also rely on its rewrite modes.
