What are QuillBot and Grammarly: Facts and Features
Anyone who wants to refine their writing should consider these two convenient tools: QuillBot and Grammarly. Understanding which one best meets your needs depends on how you evaluate each feature and its main benefits.
QuillBot
QuillBot is a tool that offers primary functions for text condensation alongside text rephrasing. Students and professionals alike choose QuillBot for its strong summarizing and paraphrasing capabilities. The application offers 9 writing modes that allow users to adjust the stylistic and tonal aspects of their text. You may benefit from this tool because it supports a wide range of languages for paraphrasing.

Here are QuillBot’s main benefits:
- The Grammar Checker tool within QuillBot scans your text for grammatical mistakes before it finalizes polished written work.
- The text paraphrasing system offers various formatting options (Standard, Fluency, Formal, Shorten, etc.) to help you find the best wording for your content.
- Summarizer provides fast document or article compression, creating short yet precise summaries.
- A Plagiarism Checker is a system that scans your work to check for possible duplicate content.
- Through its Citation Generator, you can automatically convert citations into the correct referencing standards.
We value QuillBot for its flexible paraphrasing and summarization tools, which save time when drafting. Its multiple modes allow you to vary your tone and style. However, we find that its results sometimes lack nuance, so careful proofreading is still necessary.
Grammarly
Grammarly is a tool that helps writers create texts that are both brief and direct. The application enhances tone quality, brevity, and word selection. Additionally, Grammarly’s wide range of supported platforms enables writers to achieve excellent writing standards across all their digital content creation endeavors.

Check out Grammarly’s main benefits:
- Grammar and Spell Check functions within the program to identify errors before your work becomes free of mistakes.
- The convenience tool provides recommendations to reduce the number of repetitive words, maintaining straightforward language.
- The tool enables you to set a formal or casual tone through its guided adjustment features.
- Plagiarism Detection works by comparing your content against numerous databases to verify its originality.
- The system provides wide integration with platforms like Gmail and Google Docs, allowing you to write with confidence across different web applications.
We think that Grammarly is a reliable tool for quick daily revision of drafts. The grammar check and integration with other tools make everyday editing easy. However, sometimes it simplifies the style too much, so we use it more as a helper than a final editor.
QuillBot vs Grammarly: 6 Key Differences
At We-Right Factory, we’ve tested QuillBot and Grammarly to their limits. We’ve thoroughly tested them on key parameters and are ready to provide you with the details. Let’s get into the comparison to help you decide which tool is best suited for your writing needs.
- Grammar Checking Capabilities
Grammarly reveals every grammatical and punctuation problem to users with stellar efficiency. The program detects 250 different errors in rapid succession. Having advanced style-relevant recommendation engines enables this tool to refine your writing, making it polished while maintaining accuracy. The tool provides accurate error detection, making it a worthy choice for professional proofreading situations. It highlights missing letters, incorrect punctuation marks, and grammatical errors in words. Plus, it identifies lexical inaccuracies. For example, when confusing British and American English.

In contrast, QuillBot does have a grammar checker, but it’s more basic. It may overlook minor mistakes that Grammarly would detect. The program allows you to correct errors in grammar, spelling, punctuation and word usage. It also sees nuanced errors and homophones. Still, if you’re searching for a tool that offers in-depth grammar checking, QuillBot may not suffice.

Our Verdict: We consider Grammarly as the most effective solution for grammar verification purposes. The tool’s ability to thoroughly detect errors, along with its sophisticated suggestions, makes it the superior option in this domain.
- Paraphrasing and Rewriting Tools
QuillBot’s strongest feature is its paraphrasing functionality. The tool supports 52 languages and functions specifically as a rewriting tool, offering Standard, Creative, Fluency, and five additional writing modes. The available writing modes in the system enable you to rephrase text according to various vocal and stylistic preferences. You can also benefit from a summarizer tool that transforms lengthy texts into brief outlines through this platform’s interface.

The Grammarly paraphrasing tool set doesn’t include this level of detail. It doesn’t offer a big selection of paraphrasing styles. However, the program guides users in enhancing sentence clarity, while its Generative AI features assist in revising content to some extent. You should look elsewhere for your paraphrasing demands if Grammarly doesn’t meet your desired level of depth.

Our Verdict: Among the two platforms for paraphrasing and rewriting, QuillBot emerges as the most exceptional option. Users choose QuillBot as their primary rephrasing tool for its comprehensive feature set and multiple operating modes.
- Plagiarism Checker
Grammarly has a powerful plagiarism checker that searches your text against billions of web pages. The program allows you to proofread text of up to 10,000 characters per check. This guarantees thorough and precise detection of any plagiarized content. It’s a worthwhile feature for authors who must ensure their work is original.

QuillBot also features a plagiarism checker, but it has a limitation. It’s subscription-only, and even that has a word limit. You can only check up to 25,000 words a month. Still, the results of the check are visible only with an active subscription. This could be a limitation for users who want to check the text several times.
Our Verdict: When it comes to plagiarism detection, Grammarly is the better choice in terms of budget. Its unlimited access and vast scanning ability make it a better solution for comprehensive plagiarism checks. The algorithms for detecting plagiarism in Quillbot are stronger than those of Grammarly. But its main drawback is the inability to see the result of the check (even the smallest text) without a subscription.
- Additional Writing Support Features
Through its platform, Grammarly provides you access to tools that strengthen your writing style. Among them are Proofreader, AI Grader, Citation Finder, AI Detector and Text Humanizer.
QuillBot’s primary tone capability is its diverse range of translation options. Through its SEO optimization tools, the system enhances content to improve search engine rankings. QuillBot’s writing support capabilities include AI Detector, AI Humanizer, Summarizer, and Citation Generator.

Our Verdict: Grammarly offers a more comprehensive writing assistance package than QuillBot. The style improvement features, along with tonality and clarity enhancement tools that QuillBot delivers, exceed what QuillBot provides to users.
- Integration and Accessibility
The Grammarly platform supports more than 500,000 applications and websites, including Google Docs, Microsoft Word, and various social media endpoints. Grammarly distributes its editor across multiple platforms via browser extensions for Chrome, Firefox, Safari, and Edge.
On the other hand, the QuillBot application integrates with Google Docs, as well as Microsoft Word, Chrome, and Slack.
Our Verdict: The integration abilities of Grammarly exceed QuillBot, as Grammarly supports more than 500,000 applications and websites. Along with other supporting evidence, Grammarly emerges as the winner for its vast compatibility range that extends to different platforms.
- Subscription Pricing
Both tools have their free and paid versions. With Grammarly, you may access the following plans:
- Free. It allows you to write without mistakes, see your writing tone, and generate text with 100 AI prompts.
- Pro. In Pro plan, you may rewrite full sentences, generate text with 2,000 AI prompts, detect plagiarism and AI-generated text, and get instant citations in MLA, APA, Chicago.
- Enterprise. In addition to Pro features, you get dedicated support, BYOK encryption, data loss prevention, and unlimited AI prompts.

QuillBot offers two pricing plans – a free version and a Premium subscription. Here is all the information about them:
- Free. This plan enables you to paraphrase up to 125 words, utilize two paraphrasing modes, and create basic summaries. Additionally, the AI Detector function is limited to text inputs of 1200 words or fewer.
- Premium. The subscription allows you to paraphrase unlimited text, create custom summaries, get advanced proofreading, and access unlimited paraphrasing modes plus Google Chrome, Microsoft Edge, macOS, Word, and Android integrations.

Our Verdict: For budget-conscious users, QuillBot’s Premium plan is more affordable. However, Grammarly’s Pro plan offers a broader range of features, which may justify the higher price for some writers.
