Quillbot Grammar Checker Review 2023: Can it Compete?

A famous American writer C.J. Cherryh once said that it is okay to write garbage as long as you edit brilliantly.

I agree with her. If you want to become a great writer, you have to learn and master the art of proofreading and editing your drafts.

Editing by hand, line-by-line, and word-by-word is time-consuming and, frankly, a tedious endeavor. Imagine correcting grammatical errors, spelling mistakes, and punctuational errors for a 10,000-word document.

Luckily, there’s no need for you to do any of that.

There are a lot of tools out there that you can download or use online that will check and correct grammatical errors for you for free or for a fee.

The Quillbot Grammar Checker is one of the best tools, and, guess what? It is free!

Let’s take a closer look at this too-good-to-be-true writing tool.

Quillbot Grammar Checker Overview

Quillbot is the best all-in-one editing option for text content creators, students, and professionals alike. It boasts over 50 million global users, and 85% of students report scoring better grades after using it.

It is a robust, AI-powered tool with advanced grammar-checking capabilities. It is based on the GPT-3 model developed by OpenAI.

The advanced artificial intelligence and natural language processing behind Quillbot help it possess a human-like understanding of our language and thus correct even the most negligible grammatical, punctuational, or spelling errors.

Why Quillbot Grammar Checker Stands Out

There are a lot of tools out there designed to correct grammatical errors in your write-ups, and you might be asking yourself what’s so special about the Quillbot Grammatical Checker.

That’s a totally justifiable sentiment to have.

Below, I will show you why the Quillbot Grammar Checker is a must-have tool for any writer. As a matter of fact, I’m going to make it clear to you why this tool is one of the kings of grammar-checking tools on the market.

Read our in-depth comparison between Quillbot and Grammarly, where we discussed how they are friends and not rivals and why they must be used together.

Without much ado, let’s get into it.

1. It is free!

No matter how you look at it, nothing beats free. The human species loves free stuff.

I know there are a lot of free tools that can be used to check grammatical errors out there. None come close to Quillbot Grammar Checker regarding pure versatility and functionality.

The Quillbot Grammar Checker is not only powered by advanced artificial intelligence. It is also free!

Do you know what that means? It means it’s not the same as these traditional in-built grammar checkers found in word processors like Microsoft Word and Google Docs.

This tool is robust. It can pick up even the tiniest mistakes in grammar usage or punctuational errors and correct them for you.

Not only that, Quillbot looks for formatting mistakes in your writing, like double spacing, and corrects them. If you are not that fluent in English, Quillbot will suggest a fluently rewritten option.

And you caught the ‘FREE’ part, right?

Quillbot will not ask you to provide credit card details or anything else. Quillbot Grammar checker is 110% free with virtually zero limitations.

2. Quillbot Has A Click-Fix-All Option

Fix All Errors feature of the Quillbot Grammar Checker

I have used many grammar-checking tools in my life, and some of them were alright, but what they all had in common is that they took up too much of my time correcting each error one at a time.

Imagine editing a 5000-word article. Sometimes I had to literally correct up to 1000 grammar, punctuational, and spelling mistakes individually by hand.

Now you don’t want that, do you?

Quillbot allows you to correct bulk grammar issues in a single step without going into individual details. Honestly, I can never get enough of this feature.

Quillbot has increased my productivity with literally just a single feature.

3.    Quillbot Has an Easy-To-Use Intuitive Interface

Quillbot Grammar Checker User Interface

One of the main reasons why people tend to shy away from tools that claim to be free is the annoying ads that keep on popping up with virtually every click.

And the design is often clunky with minimal inspiration and consideration for the user.

Quillbot Grammar Checker is an exception to this tendency.

As you can see above, Quillbot has a very well-thought-out user interface to provide the best user experience.

This tool is ridiculously easy to use. You can pause reading this article and head over to the Quillbot Grammar Editor dashboard, and I promise you, in seconds, you’ll be editing your document like a pro.

4. It can be customized to your preferences.

Quillbot Grammar Checker Customization

Depending on what you’re writing and the audience you’re addressing, you may want to use some slang.

If you’re writing social media content or a teen blog post, using your standard Elizabethan English won’t cut it.

The best way to talk to a younger demographic is to allow yourself to break a few grammar rules and speak to them in their language and slang.

The problem is that most grammar-checking tools, as helpful as they may be, tend to flag slang as errors. Quillbot grammar is no exception. which is fine but, in this case, annoying.

Luckily, the Quillbot Grammar Checker allows you to unflag slang words, any foreign language, or words that the AI does not recognize.

All you have to do is click on the highlighted word and the “ignore” button. That’s it. Now you can click on the ‘fix-all’ magic button, and your slang won’t be auto-corrected.

5. Powerful Integrations

Let the Quillbot Grammar Checker follow you where you work.

Writing somewhere else and pasting it into the online grammar checker is doable but not the most convenient way of editing your work.

This is why Quillbot has an extension that allows you to integrate this powerful tool with Chrome and Microsoft Word.

The importance of connecting Quillbot to these powerful tools is a no-brainer.

Integrating the Quillbot Grammar Checker into these platforms instantly improves your workflow.

You can edit your writing and correct any grammatical mistakes as you type, or you can correct them at the end. You can always use the ‘correct all errors’ magic button without switching to another tool.

Remember that the Quillbot Grammar Checker is not the same as your in-built grammar checkers that come with Google Docs or Microsoft Word.

It is far better than them, to the point that there’s no competition.

Quillbot Grammar Checker: Pros And Cons

What are the benefits and downsides of using the Quillbot Grammar Checker tool? Good question.

Everything has strengths and weaknesses. And the only objective way to judge something is to consider both its strengths and weaknesses.

It is in that spirit that I have dug up some of the clear-cut pros and cons of using the Quillbot Grammar Checker tool.


  • Generously free (Create your free account here)
  • It is extremely simple to use.
  • It has a 3-day money-back guarantee for the premium.
  • Very robust.
  • When you subscribe to the premium plan, you get additional writing tools like the summarizer tool, a plagiarism tool, a rewriting tool, and more.
  • It has important extensions.
  • It is relatively cheap compared to similar tools like Grammarly.


  • The free account is somehow limited.
  • You need to upgrade to access more advanced features.
  • The editing process is not fully autonomous.

Pricing: How Much Does Quillbot Grammar Checker Cost?

Just to make it clear, the Quill bot Grammar Checker is FREE! You don’t have to pay anything to have your school essay edited.

The paid option is for those who seek access to the super advanced editing features Quillbot has to offer.

In other words, Quillbot has two pricing plans: the free one and the premium one.

Below, we’re going to examine both of them under a microscope and figure out what you get from either of the plans.

1.    The Free Plan

Quillbot plagiarism checker free plan

This free plan from Quillbot is amazing.

It is free forever. If you decide to go this route, you’ll pay Quillbot $0 for the rest of your life but still use the tool whenever you want.

As far as grammar checking and grammar correcting go, this free plan is all you truly need for your editing tasks. This AI-powered tool will catch everything and polish your write-up with one click in a fraction of a second.

If you’re looking for more than just correcting grammar, punctuation, and spelling errors, the free plan has more in store for you.

The free plan will get you:

  • 125 words in the Paraphraser
  • Standard and Fluency modes
  • Three synonym alternatives
  • 1 Freeze word or phrase
  • 1200 words in the Summarizer

However, the free plan will not get you:

  • Faster processing speed
  • Advanced grammar rewrites
  • Compare modes (Desktop only)
  • Plagiarism checker
  • Tone detection

To get these features, you’ll need to subscribe to the premium plan.

Note: No credit card is required.

2.    The Premium Plan

Quillbot Premium Plans
  • Best for: Professional writers
  • Price: $4.17 to $9.95 per month.
  • Discount: 33% when billed semi-annually and a massive 58% when billed annually.
  • Promotion: 3-day money-back guarantee and a Quillbot 40% back-to-school discount.

Quillbot is cheap compared to other popular tools like Grammarly, which costs about $30 per month when billed monthly. That’s almost a $20 gap!

Affordability is not the only best part of the premium plan.

For me, it is the extra features that come with it that make sparing a little change every month for your premium subscription worth it.

What I like the most about the premium plan is that you can pause your subscription.

This means that when you take a break from writing, you can tell Quillbot to stop billing your account until the day you decide to resume using the tool again.

How cool is that?

Don’t forget that when you cancel your subscription within the first three days of purchase, for whatever reason, Quillbot will refund your money.

There’s no risk of losing your money to Quillbot if you try it out and find their tool to be trash.

All features in the free plan are also available under the premium plan, plus the following:

  • Unlimited words in the paraphraser
  • Standard, Fluency, Expand, Shorten, Formal, Simple, and Creative modes.
  • 4 possible synonyms
  • Unlimited Freeze words and phrases
  • 6000 words in the summarizer.
  • Faster processing speed.
  • Advanced grammar rewrites
  • Compare modes (Desktop only)
  • Plagiarism checker
  • Tone detection

All of this can be accessed for as little as $4.17 per month if you choose the annual billing method.

Note: Discounts and promotions are subject to sudden withdrawals or unannounced changes.

What Else Does Quillbot Have To Offer?

1.    The Plagiarism Checker

Quillbot Plagiarism Checker

There’s so much content on the web that writing something purely unique is close to impossible these days.

This Quill Plagiarism Checker scans your text and compares it to billions of web-published content. After a deep analysis, it gives you a detailed report highlighting the plagiarized portions of your work and a total originality score.

With this tool, you can scan and flag plagiarism in your work in over 100 languages.

In addition to regular English, the Quillbot Plagiarism Checker accepts input in other languages such as French, Portuguese, Spanish, Arabic, Russian, Japanese, and Chinese, just to name a few.

Your premium subscription gets you about 20 scans per month.

Note: Quillbot regards 250 words as a single page.

2.    The Co-Writer

Quillbot co-writer

The Co-writer is what you need if you’re looking to increase your productivity levels. It combines all Quillbot’s tools into a single place.

I’m talking about paraphraser, summarizer, citation generator, et cetera. All your writing, editing, and polishing can be done in a single tab with no distractions.

The Co-Writer can also help you with your online research and note-taking with its AI-assisted autocomplete capabilities.

This is the tool you need in order to avoid having an all-over-the-place workflow.

3.    The Citation Generator

Quillbot Citation Generator

As suggested by the name, Quillbot Citation Generator allows you to create full and in-text citations in over a hundred citation styles, including the popular ones such as the APA, MLA, and Chicago styles.

This tool right here is a lifesaver.

There’s no way in 2023 you will sit there and manually look for sources and write the sources down one by one, following all the citation guidelines for a particular citation style.

I mean, that’s just mind-numbing and torture. Quillbot will scan your document and look for correct sources and generate a citation list for you, which can be copied to your clipboard or exported to Microsoft Word.

And oh, did I tell you that the Quillbot Citation Generator is free?

4.    The Paraphraser

Quillbot Paraphrasing Tool

You know that feeling when you write a well-thought-out piece you invested a lot of time in but somehow it just sounds off?

That moment when you feel like you’re not using the right words and sentences that are not connecting the way they’re supposed to?

And what about that moment when you finally write something epic, and you’re all over the moon about it, but the moment you try running it against a plagiarism checker, it ends up being flagged, even though you’re 100% sure every word in your work came right from your skull?

We have all been there before. At least I have, but not anymore.

Quillbot has a solution to this problem, and it is the Quillbot Paraphraser.

This AI-powered state-of-the-art tool can rephrase any text and come up with multiple variants of it.

You can also find synonyms for different words by highlighting a specific word in your write-up and selecting the appropriate synonym.

Plus, remember that Quillbot can be integrated with Google Chrome and Microsoft Word.

This means you can take this magic elsewhere apart from the online Quillbot editor and still work wonders.

5.    The Summarizer

Quillbot Sammarizer tool

This tool is one of those things you don’t know you need until you get it and can’t seem to get over it.

The Quillbot Summarizer is a well-kept productivity hack secret that no one talks about but keeps to themselves.

I mean, in this day and age of information and fast lifestyles. We all want to be informed and never miss out on trendy stuff or popular gossip, but no one likes reading anymore.

This tool takes long-form articles, social media posts, research papers, or anything text-based and summarizes it into a single consumable paragraph with everything you need to know.

It uses natural language processing (NLP), or some creepy AI stuff, to scan through a huge chunk of text, find out the main ideas being communicated, and present them to you.
