Writing can be a challenging endeavor, especially when trying to maintain perfect grammar and error-free content. Thanks to technological advancement, we now have advanced AI writing tools that help writers improve and polish their work.

Among the top contenders on the market are Quillbot and Grammarly, both of which offer unique features and claim to enhance writing proficiency, but in slightly different ways. In this comparison, we will thoroughly evaluate and contrast these two popular writing assistants to help you determine which one is best for your needs.

Overview of Quillbot

Quillbot is an AI-powered writing tool that stands out for its remarkable paraphrasing capabilities. Quillbot utilizes cutting-edge natural language processing (NLP) techniques to help users write better and find new phrases.

In addition to paraphrasing, Quillbot offers several features that assist you with your writing, including summarizing, grammar checking, plagiarism checking, citation generation, and AI content creation.

With an intuitive user interface, multiple writing modes, thesaurus support, and seamless integration with popular platforms, Quillbot becomes a powerful tool for writers, students, and professionals looking to avoid plagiarism or simplify complex ideas.

Overview of Grammarly

Grammarly is a popular AI-integrated writing tool renowned for its ability to effectively modify, correct, and proofread content. It offers a wide range of features, including real-time grammar checking, contextual suggestions for clarity and conciseness, vocabulary enhancement, plagiarism detection (in the premium version), and support for multiple writing styles.

Grammarly’s recent introduction of the GrammarlyGo tool helps it compete with Quillbot neck to neck by enabling users to enhance their sentences and even generate new content.

Quillbot vs. Grammarly: Differences

Although Quillbot and Grammarly are both AI writing assistant tools, they serve different purposes. Quillbot is popularly known as the best paraphrasing tool, whereas Grammarly excels as the best grammar checker. Alongside this prominent difference, the two tools have several other distinctions:

1. Paraphrasing

Grammarly and Quillbot both offer paraphrasing capabilities, but one clearly excels over the other in terms of accuracy and effectiveness.

Grammarly’s new AI tool, GrammarlyGO, does an incredible job at rephrasing short paragraphs and long blocks of text by rewriting the whole thing in a completely unique way without losing the original meaning. You can also set the tone for the rephrasing, such as Neutral, Formal, Casual, Informative, and more.

Quillbot’s paraphraser, on the other hand, lacks significantly in its paraphrasing ability, which is shocking considering that it’s primarily known as a paraphraser tool. It works by simply replacing some of the words in the sentences with synonyms, which aren’t always entirely accurate either. In the premium version, you can set the tone for paraphrasing and even choose to expand or shorten a sentence while rewriting.

One thing that we do like about Quillbot’s paraphraser tool allows you to paraphrase sentences in several languages, including English, Spanish, German, French, Chinese, Italian, Japanese, Romanian, Polish, and more.

2. AI Content Creation

Quillbot lets you generate content from scratch using its Suggest Text feature, and so does GrammarlyGO. Both tools do a great job at suggesting and writing new content from scratch, but they differ in the way they work.

Quillbot’s AI content creation feature works by suggesting the next paragraph that you should incorporate into your writing. The tool requires constant input from the user, and you need to write a sentence or two yourself before it can generate the next content suggestion. This can be inconvenient if you’re looking to write an entire essay or article without putting in any information yourself.

Thankfully, GrammarlyGO understands this need and works similarly to some of the best AI writing tools, like Jarvis and ChatGPT, by generating entire essays and articles of 1000+ words, all on its own. All you have to do is type in the topic you want to write about and press Enter.

The tool generates an entire article within just a few seconds! What’s more? You can also request the AI to refine the content it produces by giving commands such as “make it more descriptive” or “make it sound formal” or ask it to rephrase its own work.

3. Translator

The one feature that Quillbot has, but Grammarly lacks, is a built-in translator that allows you to translate content between different languages. You can translate content into 34 different languages using Quillbot’s translator.

Grammarly does not offer any translation capabilities, and even its new GrammarlyGO feature is only available in English.

4. Writing Style and Tone

Grammarly shines in understanding and adapting to different writing styles and tones. It offers personalized suggestions on fluency, consistency, clarity, engagement, delivery, and a style guide based on the tone set and the target audience. It also intelligently provides vocabulary ideas and synonyms for words as they appear in your document.

Additionally, you can also ask the GrammarlyGO AI assistant to identify any gaps in your writing, provide suggestions on improving the content or even rewrite entire paragraphs in your desired tone and style.

Quillbot is not as nuanced in understanding the subtleties of different writing styles. The most it does is identify passive sentences and offer suggestions for turning them into active. However, this feature is only accessible in the premium version of the software.

Quillbot vs. Grammarly: Similarities

Despite their differences, Quillbot and Grammarly share a few similarities:

1. Browser Integration and User Interface

Both Quillbot and Grammarly have made significant efforts to create user-friendly interfaces. They offer seamless integration with web browsers and popular word processors, making it incredibly convenient for you to access their features. Additionally, their user interfaces are intuitive, making it easy for writers of all levels to navigate and utilize the tools effectively.

2. Plagiarism Checker

Both Quillbot and Grammarly offer plagiarism checkers that need to be accessed via a premium subscription to the platform. They function similarly, examining your content against their databases to provide information about originality percentages and instances of plagiarism as well as presenting matched results along with their sources.

However, Quillbot’s plagiarism checker is somewhat restrictive, as it only allows you to check 20 pages per month, even with a premium subscription. Grammarly does not have any such restrictions.

3. Grammar Checking

Quillbot and Grammarly both offer effective grammar-checking functionality, correctly identifying punctuation, agreement, capitalization, and spelling mistakes. However, both offer functionalities that make them stand out.

Grammarly offers an explanation for every grammar suggestion that it makes, which helps improve your overall grammar.

On the other hand, Quillbot’s Grammar Checker stands out due to its capability to not only provide grammar checking for English but for German, French, and Spanish. This is a great feature, especially if you often write in languages other than English. This functionality is missing from Grammarly, which only allows grammar checking for the English language.

4. Premium Plans

Both Quillbot and Grammarly offer the convenience of choosing between premium and free versions of their writing assistant tools. With Quillbot’s premium version, you can access unlimited words in the paraphraser, faster processing speeds, plagiarism checking, and more. It has the following three plans:

• Monthly: $9.95
• Semi-annually: $39.95 billed every six months
• Annually: $49.95 billed every 12 months

Grammarly offers two different subscription plans: Premium and Business. The Premium version offers everything in the free version, plus advanced grammar checking, genre-specific writing suggestions, plagiarism checking, and enhanced writing insights. You can choose to pay $30 monthly, $60 quarterly, or $144 annually for the premium plan.

In contrast, the Business plan is mainly for businesses and teams and offers advanced security and style guide features. Grammarly offers a 7-day trial for its Business plan, and you can choose a monthly plan at $25 per member or opt for the annual plan at $12.25 per member per month.

5. Citation Tools

Quillbot and Grammarly both have a citation generator tool that helps you generate citations and check for proper citation formats. With support for APA, MLA, and Chicago styles, they offer a free solution for generating full and in-text citations for your academic papers and essays.

However, Quillbot’s citation generator is a lot simpler to use. All you have to do is paste the URL of the website you want to generate citations for and choose the citation format, and the tool generates a citation within seconds.

Grammarly’s citation tool is a lot more complicated, and you need to manually enter all the required details for it to generate a citation.

However, with Grammarly’s Chrome extension, you can simplify this problem.

Simply go to the website you need citations for and click Get Citations at the bottom of the screen to generate auto-citations in your desired citation format.

Quillbot vs. Grammarly: Ideal Users

Quillbot is best suited for students, academics, content creators, and multilingual writers. It aids students and academics in avoiding plagiarism, grammar checking, auto-citations, and translations, while content creators benefit from AI content generation.

On the other hand, Grammarly is suitable for writers of all levels, including students, academics, business professionals, and content writers. It caters to anyone striving for polished writing, making it a versatile tool for several users.

Quillbot and Grammarly are powerful AI writing assistants, each with unique features catering to different writing needs. While Grammarly initially focused on grammar checking, style recommendations, and plagiarism checking, it now offers content generation, rewriting, and summarizing capabilities, similar to Quillbot.

In our comparison, we found Grammarly to be better at almost everything except for translating, plagiarism checking, and affordability in premium plans. Quillbot, however, is great for multilingual users and people who require basic grammar checking and summarizing.
