QuillBot is an AI writing suite that paraphrases text, checks grammar, and improves fluency for students and professionals.

QuillBot is an AI writing suite built around a paraphraser, a grammar checker, and a set of supporting tools for clearer writing. It is made for students, content creators, and working professionals who want to rewrite, correct, and polish text without switching between separate apps. You can paste, type, or upload your work and run it through paraphrasing, summarizing, citation, and originality checks in one place.
QuillBot's core draw is its paraphrasing engine, which rewrites sentences in different tones and styles while keeping the original meaning. Rather than acting as a single grammar checker, it bundles paraphrasing, summarizing, citation, plagiarism detection, and AI detection into one workspace, so you stay in one tool instead of copying text between tabs.
The paraphraser offers built-in modes (Standard and Fluency on the free plan, plus 9 modes and custom modes on Premium), works in 23 languages, and lets you adjust synonym frequency. The grammar checker, summarizer, and citation generator handle routine cleanup, while the plagiarism checker and AI detector help verify originality before you publish.
QuillBot runs where you already write through Chrome and Edge extensions, a macOS app, a Word add-in, and Android and iOS apps. Documents save into QuillBot Flow, and Premium adds faster processing, larger summaries, and unlimited paraphrasing and humanizing.
QuillBot holds a 4.4 out of 5 rating on G2 from roughly 113 reviews, and its Chrome extension is rated 4.5 out of 5. The company reports more than 35 million writers across 180+ countries. Users praise how quickly it rewrites text and improves clarity while keeping the meaning intact. The most common criticism is that the free version is limited: paraphrasing caps at 125 words, and several stronger features are locked behind Premium.
The free tier is enough to test the paraphraser and grammar tools, while Premium unlocks unlimited rewriting and the full toolset for regular writers.
