All you fantastic (and soon-to-be fantastic) writers out there know you need the best writing tools if you want to create writing that’s fluent, error-free, and original. So you’ve been asking: Which is better, QuillBot or Grammarly?

In this article, we break it down for you. Read on to learn about the key features of these two tools, how they compare, their price points, and who should use them.

QuillBot features and overview

QuillBot is centered around improving your writing holistically, rather than correcting errors. Our AI has analyzed millions of existing texts, and learned how to offer suggestions that help you write clearly and impactfully.

Our founders initially developed QuillBot to assist with paraphrasing. Since then, its use cases have expanded. It now offers the following:

  • Paraphraser –  rephrases your text in a variety of styles. It offers two free modes (Standard and Fluency) plus five Premium modes and unlimited Custom modes. Currently, Paraphraser works in 23+ languages.
  • Summarizer – helps you save time by condensing long texts into a list of key sentences or a single paragraph
  • Grammar Checker – corrects errors in English, German, French, and Portuguese
  • Translator – converts text into 45+ languages
  • Plagiarism Checker – scans a text to identify content that’s not original and helps add missing citations
  • Citation Generator – automatically cites sources in hundreds of citation styles, generates bibliographies, and allows you to save and organize your citations
  • QuillBot Flow– Our AI-first word processor. QuillBot Flow provides a central dashboard for all of our tools, and assists with research, citations, and much more. Plus it offers generative AI to spark ideas as you write. You can generate outlines, suggest text, add examples, and more.
  • Word Counter – displays the number of words and characters in your text, lets you choose whether to count spaces, and shows character limits for different social media platforms

Within these tools, you’ll find even more helpful features, such as the option to:

  • Select from American, British, Canadian, or Australian English.
  • Tone insights to help you connect with your audience.
  • Eliminate contractions and/or passive voice.
  • Determine whether you want more or fewer synonym suggestions.
  • The ability to prevent specific terms from changing in Paraphraser.

When it comes to creating your best work yet, QuillBot has the tools to help you with every step of the writing process.

QuillBot pros: QuillBot focuses on strengthening every aspect of your writing, and offers support from the first drafts to the final edits. It doesn’t just fix mistakes or auto-generate text. You’ll get help with research, writing, refining, reviewing, and much more. With QuillBot, you can enhance your natural abilities and write efficiently and effectively.

QuillBot cons: Free accounts are subject to limitations. For example, free accounts can only paraphrase 125 words at a time, only summarize 1,200 words at a time, only translate 5,000 words at a time, et cetera. Additionally, the number of times free accounts can use generative AI is subject to a daily limit of 50 times per day. Some features, such as recommended rewrites, are only for Premium accounts. However, with a Premium account, you don’t have to work with these limitations. By upgrading to Premium, you unlock the full power of QuillBot.

Grammarly features and overview

While Grammarly offers many features, its core focus has been spelling, punctuation, and grammar checking. It's a great tool for spotting mistakes such as typos and commonly confused words. You can set it to American, British, Canadian, Australian, or Indian English.

Besides cleaning up your grammar, it offers assistance in the following areas:

  • Tone – analyzes your words and sentence structure to give you feedback and suggestions for the right tone
  • Inclusiveness – points out words and phrases that may be offensive or exclusive and suggests alternatives
  • Clarity – highlights long sentences and other structures that may be unclear and suggests clearer phrasing
  • Engagement – finds repetitive word choices and other writing flaws that cause readers to lose interest and suggests more engaging choices
  • Fluency – detects points of confusion between English and other languages and suggests phrasing to make your text read more naturally
  • Formatting – suggests formatting that can make the text easier to read, such as bullet points and paragraph breaks
  • Ideas – generates outlines, drafts text, and offers other ideas to help you overcome writer’s block or organize your thoughts
  • Plagiarism – searches the internet for similar texts and shows you where yours appears to be unoriginal
  • Citation – creates citations in Chicago, APA, or MLA style using information you enter in a form
  • Emails – summarizes emails for you and suggests responses
  • And more!

Grammarly is a good tool for correcting mistakes, improving your sentences, and enhancing collaboration in writing teams.

Grammarly pros: Grammarly is a great choice for ensuring your writing is clear and free of errors. It’s also great for ensuring your tone is appropriate, even if you just have a free account. And if you’re a working professional or content creator, it can even help you sound on-brand. Grammarly also offers inclusivity settings, which can help reduce bias in your writing and prevent you from unintentionally offending your audience.

Grammarly cons: Grammarly primarily focuses on English writing. It is geared towards editing and error correction, rather than supporting writers holistically. Some features are only available to Premium users. Additionally, even Premium accounts have limits on the use of certain AI features, unlike QuillBot’s website features.

Who uses QuillBot or Grammarly?

The takeaway from all of the information above is that both of these tools have their advantages and disadvantages. It all depends on the type of writing you’re doing, so let’s look at a few specific use cases.

AI content generation

If you’re struggling with writer’s block or can’t seem to organize your thoughts, both tools can create an outline, complete your sentence or paragraph, suggest the next sentence, and more based on what you’ve already written. As you write, they both provide metrics that can help you meet your writing goals. Grammarly offers an analytics dashboard in its Business plan that shows metrics for all the writers as a group.

But QuillBot allows its writers to use this feature more extensively. Grammarly limits free accounts to 100 prompts per month, and Premium accounts to 1,000 prompts per month. Meanwhile, QuillBot allows free accounts 50 prompts per day (totaling about 1,500 a month!), while Premium accounts get unlimited access to this feature. As you can see, even QuillBot’s free plan offers more generative AI access than Grammarly’s paid plan.

Academic writing

Both QuillBot and Grammarly are helpful for students and educators alike. They are both excellent at making text more concise and formal, checking for plagiarism, and citing sources. But QuillBot also offers a more robust Citation Generator, which allows you to create, save, and organize entire bibliographies.

Besides its citation benefits, QuillBot is superior for students because QuillBot Flow offers enhanced research capabilities. QuillBot Flow allows you to research in the same tab you write in, and allows you to ask AI questions about your research. It also lets you save sources, take notes, and much more. While Grammarly does offer a word processor, it does not offer the same enhanced research capabilities.

Business writing

Grammarly is used for creating content that is inclusive, on-brand, and able to connect with the target audience. A team of content marketers or business writers can keep their content’s style and brand voice consistent with a Grammarly Business plan. But for professionals looking to optimize their writing for SEO, QuillBot may be a better choice. Here, QuillBot’s Freeze Words tool comes in handy. It lets you specify words that you don’t want to be changed, such as keywords. Finally, bloggers and content creators can benefit from the AI generation and creative functions in both tools.

Longform writing

Authors of longer pieces, such as books and white papers, can benefit greatly from both tools’ error-correcting, wordsmithing, and AI generation features. Fiction authors may prefer Grammarly since they might not need QuillBot’s research capabilities. On the other hand, nonfiction writers may find these functions helpful. Any writer who struggles with writer’s block or wants to enhance their productivity will likely love QuillBot Flow. This is because QuillBot Flow offers a variety of brainstorming and editing features to help writers feel inspired and boost their efficiency.

Language learning

Multilingual writers can find value in QuillBot’s Fluency mode, which is free in Paraphraser. While Grammarly does offer fluency suggestions, they are available to Premium users only. QuillBot also offers translation capabilities, and allows writers to view translations side-by-side with their original text. Additionally, QuillBot offers multilingual options in many of their tools.

On the other hand, Grammarly focuses primarily on English and lacks the same multilingual capabilities. However, they do have one advantage in that they offer the additional option of Indian English, while QuillBot only has American, British, Canadian, and Australian English.

Which is better, QuillBot or Grammarly?

When choosing between QuillBot and Grammarly, the winner depends on your needs. Let’s review and sum it up:

Because Grammarly is primarily a spelling, punctuation, and grammar checker, comparing the accuracy of the two means looking at only the grammar checkers of QuillBot and Grammarly. In this regard, not only does QuillBot offer more free suggestions to improve your grammar, but it also comes with a whole array of other tools to enhance your writing.
