Grammarly vs QuillBot: Which Writing Tool Should You Choose?

What Are Grammarly and QuillBot?
What is Grammarly?
Grammarly is a writing assistant. It checks grammar, spelling and punctuation, flags wordy or unclear sentences, and detects tone. Paid plans add stronger rewrites, tone adjustment, plagiarism detection and a larger monthly allowance of AI prompts. It works in browsers, apps and common document editors, so it follows you across emails, docs and posts.
Pros- Checks writing in the places you already work
- Useful free plan for grammar and spelling
- Suited to professional and team communication
- Rephrasing is not its main strength
- Pro costs more than QuillBot Premium on annual billing
- Free AI prompts are limited
What is QuillBot?
QuillBot began as a paraphrasing tool and now bundles related writing tools: a paraphraser, grammar checker, summarizer, citation generator and translator. You paste text, choose a mode, and get a reworded version. Premium removes most free-plan limits and adds a plagiarism checker.
Pros- Dedicated paraphrasing workflow
- Several tools in one place
- Lower annual price than Grammarly Pro
- Free paraphraser is capped at short passages
- Rewrites can drift from the original meaning
- Monthly billing is expensive
Grammarly vs QuillBot: Feature-by-Feature Comparison
Grammar and Spelling Checking
Both tools catch spelling, grammar and punctuation errors. Grammarly is built around this job and checks as you type in many apps. QuillBot’s grammar checker is one tool inside a larger set, usually used on a draft you paste in. We have not seen reliable independent evidence that one is more accurate, so test both on your own writing.
Paraphrasing and Rewriting
This is the clearest difference in the Grammarly vs QuillBot paraphrasing question. QuillBot gives you a dedicated space to reword a passage, switch modes and compare versions. Grammarly suggests rewrites inside the text you are already editing. If you regularly reshape existing copy, a dedicated paraphrasing workflow saves steps. Always read the output to confirm the meaning has not changed.
AI Writing Assistance
Both products now include generative AI. Keep three things separate: grammar correction fixes errors, editing suggestions improve existing sentences, and AI generation creates new text. Check generated text for accuracy before you publish it.
Tone, Clarity and Style
Grammarly detects tone and suggests clearer, more concise wording, with more control on Pro. QuillBot handles style mostly through its rewriting modes, such as fluency-focused output. Confirm which tone features sit in which plan on the official pages.
Summarization and Research Workflows
QuillBot has a dedicated summarizer and a citation generator, which suits research-heavy work. Summaries and generated citations can contain mistakes, so check them against the original sources.
Plagiarism Checking and Originality
Both tools offer plagiarism checking on paid plans. These checks compare text against other content and flag possible matches. That is different from AI-content detection, and no detector can definitively prove who wrote a document. Treat results as a prompt for review, not a verdict.
Integrations and Ease of Use
Grammarly is designed to sit inside your browser, desktop and mobile apps. QuillBot offers a browser extension and document add-ins, but many people use its website for rewriting. If you write across email, docs and social tools all day, an always-on assistant is more convenient. Confirm the current integration list on each official site.

Choose Grammarly if you want ongoing proofreading and clearer communication across the apps you use.
