Frequently Asked Questions About Grammarly vs QuillBot

Is Grammarly better than QuillBot for academic writing?

For academic writing, Grammarly generally offers more comprehensive grammar and style checks that can be crucial for formal papers. Its plagiarism checker is particularly valuable for ensuring academic integrity, while its formal tone suggestions help maintain consistent scholarly language throughout your work. In our testing, Grammarly caught subtle grammar issues that many other tools missed, which is essential when your grade depends on clean, error-free writing.


QuillBot, meanwhile, shines in different aspects of academic writing. Its multiple paraphrasing styles (with 9 different modes in the premium version) give you incredible flexibility when you need to restate ideas from sources without plagiarizing. This can be a lifesaver when you're stuck trying to incorporate research while maintaining your own voice. Many students claim they use QuillBot's summarizer tool to condense complex research articles – particularly helpful when you're working with lengthy source materials.


For the best results, many academic writers actually use both tools together – Grammarly for polishing grammar and style, and QuillBot for paraphrasing and restructuring sentences to improve flow and clarity. Each tool has free versions that work well together for basic academic writing needs.

Which is more affordable, Grammarly or QuillBot?

QuillBot is significantly more budget-friendly with its Premium plan starting at just $4.17 per month (when billed annually at $49.99/year), while Grammarly's comparable plan starts at $12 per month (annual billing at $144/year). This price difference of nearly $100 per year makes QuillBot about 65% less expensive, which is substantial for students, freelancers, or anyone on a tight budget.


Both tools offer free versions, but QuillBot's free tier provides more substantive features. While Grammarly's free version offers basic grammar and spelling checks, QuillBot's free tier includes limited access to its paraphrasing tool with two writing modes (Standard and Fluency), as well as three synonym options per word. You can also process up to 125 words at once and access the summarizer tool with a 5,000-character limit in the free version.


For occasional users who just need basic writing help, both free versions work well. However, if you're looking for the best value in a premium tool, QuillBot's more affordable pricing combined with its generous feature set makes it particularly appealing. Many users who upgraded to QuillBot Premium mention that the ability to process 10,000 characters at once and access all paraphrasing modes justified the cost almost immediately.

Can I use both Grammarly and QuillBot together?

Yes, and many writers find this combination particularly powerful! Based on feedback from both communities, a common workflow is to draft your content, run it through Grammarly first to fix basic grammar and spelling errors, then use QuillBot to enhance phrasing and sentence structure. This two-step approach gives you the best of both worlds – Grammarly's accuracy in error detection and QuillBot's creativity in rephrasing.


The good news is that both tools offer browser extensions that work simultaneously without conflicts. You can have both Grammarly and QuillBot extensions active in Google Docs, for example, switching between them as needed. We've found this especially useful when working on important documents where you want both perfect grammar and engaging variations in your writing style.


Many content creators use Grammarly during the drafting and editing phases, then apply QuillBot as a final polish to improve readability and flow. Others use QuillBot first to generate variations of their content, then run those variations through Grammarly to ensure everything remains grammatically sound. There's no right or wrong order, experiment to find what works best for your writing process!

What integrations do Grammarly and QuillBot support?

Grammarly offers more extensive integration options, making it accessible nearly everywhere you write online. Its browser extensions (Chrome, Firefox, Edge, and Safari) work seamlessly across most websites, email platforms, and social media. What makes Grammarly particularly convenient is how it automatically activates when you start typing in almost any text field online, from Gmail to Twitter to WordPress.


Beyond browser extensions, Grammarly provides dedicated desktop apps for Windows and Mac that let you edit documents directly. It also offers mobile keyboard integrations for iOS and Android, meaning you can use Grammarly's suggestions while texting or writing emails on your phone. For Microsoft users, Grammarly has a native Microsoft Office integration that works directly within Word and Outlook.


QuillBot has fewer integrations but covers the essential bases. Its Chrome, Edge, and Safari extensions work well, and it integrates directly with Google Docs and Microsoft Word. While QuillBot doesn't have quite the same "works everywhere" approach as Grammarly, many users actually prefer its more focused integration strategy. Instead of trying to correct everything you type everywhere, QuillBot is designed to be called upon when you specifically need its paraphrasing or summarizing features.


The integration you'll find most valuable depends largely on your writing habits. If you want continuous support across all platforms, Grammarly's wider integration range is better. If you primarily work in Microsoft Word or Google Docs and prefer to use paraphrasing tools deliberately rather than automatically, QuillBot's focused approach might suit you better.

Which tool is better for non-English languages?

QuillBot has a clear advantage for non-English users with support for over 30 languages in its translation feature. While its core paraphrasing tool works best with English, the ability to translate content between languages makes it valuable for multilingual writers. In our testing, we found QuillBot particularly useful for translating content from languages like Spanish, French, and German into English and then refining the translation with its paraphrasing tools.


Grammarly, on the other hand, currently only supports English content. While it does recognize various English dialects (American, British, Australian, Canadian, etc.) and can help you maintain consistency within your chosen dialect, it doesn't offer any support for writing in other languages. This is one of Grammarly's most significant limitations for international users or multilingual content creators.


If you frequently work with multiple languages, especially if you need to translate content before editing it, QuillBot is definitely the better choice. Many users who write in both their native language and English claim they use QuillBot to bridge the gap, first using its translation features and then its paraphrasing tools to make the translated text sound more natural.


It's worth noting that neither tool is a complete replacement for native language fluency or professional translation services for critical documents. However, for everyday multilingual writing needs, QuillBot offers significantly more flexibility.
