What Is Quillbot?

Quillbot is known for its enthralling paraphrasing capability, where an incorrect sentence gets detected and transforms into a well-drafted, grammatically correct statement. 

Using Quillbot is no rocket science. You just have to copy and paste the content and click a button. Boom, you are good to go with the best-rephased content. 

Quillbot vs Grammarly - Quillbot Overview

In Quillbot, you get plenty of writing modes, which include standard, fluency, formal, simple, and creative. Say you are writing an employment letter to your superior, and obviously, you would want to sound formal, but you might accidentally use certain informal words.

In such cases, Quillbot becomes a life savior and rewrites the content in a formal tone for you. You are basically getting fully drafted content by artificial intelligence. How cool is that? 

Even if you had written an essay on something but did not hit the word count marked by your teacher, Quillbot has got your back since it has unique features like expanding and shortening, which literally expands and shortens the desired paragraph or sentence that has been pasted.

What’s more? Quillbot is supported via Google Docs, a great advantage for students and writers since most of them use Google Docs for their school essays, writing gigs, and projects, respectively.

Who Should Use Quillbot?

Quillbot is suitable for:

  • Content publishers who require SEO optimization tools.
  • Students who demand a paraphrasing tool to write essays.
  • Anyone who wants to expand/shorten their content to hit the word count.
  • People who need a summarizer to give an overview of specific content.

Since Quillbot and Grammarly come in free versions, you can use both simultaneously. I did that, and it was effective, primarily with features like tone detection and expanding/shortening tools.

Quillbot key features

Following are the features of the Quillbot that make it stand out from other tools.

Let’s have a look at the exceptional features of Grammarly.

1. Grammar checking tool

The grammar checking spots all the errors in real-time and instantly enhances the content.

2. Advanced genre-specific suggestions

Although you might have written the content in a specific genre, the third-party proofreader cannot grasp the genre and replace specific words. 

 Grammarly - Specific Suggestions

With Grammarly, you can forget all that since the advanced genre-specific suggestions perform excellently well and show accurate results.

3. Tone detection

Isn’t it amazing if you could instantly get human-like feedback on how your content sounds? 

Grammarly has the outstanding feature of tone detection, which can detect the tone of your content within seconds and tell you if it is formal or informal.

It is evident that Grammarly definitely works towards improving its users’ English better.

Main Differences: Quillbot vs Grammarly (My Experience)

You have read about the features and what all Quillbot and Grammarly hold in store for you, but what makes Quillbot different from Grammarly?

Here are a few key differences I found during my tests for Grammarly and Quillbot.

1. Grammar checking

There is no denial on the fact that Quillbot provides a grammar-checking tool, but Grammarly has the best AI-powered grammar detection and does it perfectly. 

While both platforms let you check for grammatical errors, Grammarly is solely made to check your content for any grammatical errors. Quillbot overlooked many minor mistakes, but Grammarly was quick to catch up on them. 

Again, if you compare the free versions of both tools, Quillbot and Grammarly have equal ways of helping you. However, Grammarly Premium takes a step ahead with its powerful grammar detection.

Verdict: While both have a grammar checker, Quillbot falls a little behind Grammarly in terms of grammar checking. With Grammarly, you can focus highly on the correctness of your content. 

2. SEO optimization tools

The most powerful feature that is absent in Grammarly but present in Quillbot is the SEO optimization tools feature which plays a significant role in optimizing your written content.

As a writer, the SEO tool in Quillbot immensely helped with the optimization process.

On the other hand, Grammarly doesn’t specifically provide SEO tools.

Verdict: Quillbot clearly takes the lead against Grammarly when it comes to SEO tools. 

3. Paraphrasing tool

The most talked-about feature in Quillbot is extraordinary. 

Although Grammarly can rephrase concise words into a new sentence with zero mistakes, the paraphrasing tool in Quillbot does it better. Additionally, you can rephrase sentences only if Grammarly detects it, but Quillbot allows users to do it overall.

Quillbot is widely popular for its paraphrasing feature. After all, Quillbot’s paraphrasing capability brought the tool into the limelight. You can easily paraphrase your existing content to get entirely new content. This feature is excellent for people who want to repurpose their existing content and save the manual hassle. 

Grammarly doesn’t have a particular tool for Paraphrasing. 

Verdict: Quillbot is clearly a winner when it comes to paraphrasing. 

4. Plagiarism checking

Like the paraphrasing tool in Quillbot, Grammarly has a competitive feature called plagiarism checker, which performs significantly well. 

You can detect duplicate content in no time and instantly replace it with original content with the help of Grammarly.

On the other hand, Quillbot also has a built-in plagiarism checker which supports more than 100+ languages. Moreover, you also get a detailed report of plagiarism along with the source. 

Verdict: While both offer their built-in plagiarism checker, Grammarly takes the lead here. This is because Quillbot has restricted scans. You can only check up to 20 pages with Quillbot, whereas Grammarly doesn’t put limitations on the number of content you can check. 

5. Summarizer tool

A tool that minimizes the workflow and smoothens your experience would be the summarizer tool in Quillbot, which is absent in Grammarly. 

Although Grammarly has other interesting tools to back up your content, the summarizer tool is an added feature that is less likely to be present in other competitors in general.

The summarizer tool allowed me to get an overview of the content I wrote. Instead of reading the entire article, I used the summarizer tool to get it done within 2 minutes.

Verdict: Quillbot takes the lead here since Grammarly doesn’t have a dedicated Summarize tool. 

6. Addons & Extensions

Addons and Extensions are the best way to check any document through Quillbot and Grammarly without logging in to your account repeatedly. Grammarly offers more extensions and plug-ins than Quillbot. You can use Grammarly through Chrome Extension, Safari Extension, MS Word, Firefox, and Google Docs.

Quillbot also offers MS Word extension, Chrome Extension, and Google Docs add-on. These extensions save you a lot of time because you don’t have to go back and forth on the official website to check your documents.

Verdict: Both tools have excellent Add-ons and extensions that come in handy. You can use Quillbot and Grammarly on other platforms seamlessly. 

Best Suitability of Quillbot and Grammarly

Quillbot and Grammarly can be used simultaneously for different reasons and purposes since they offer different benefits and features. 

Regarding the suitability of Quillbot and Grammarly, you might have to look through certain criteria and make a wise decision. Let me help you with that from my experience:

Pricing Verdict: Quillbot vs Grammarly 

Quillbot and Grammarly have standard versions set up for free so that users can access them without paying any fee.

Quillbot Free

You can use Quillbot for free simply by going to the official Quillbot website or clicking on www.quillbot.com. There are no hidden fees or limited-period free trials. Quillbot is entirely free. Still, certain features in Quillbot are limited in the free version, but you can unlock them by opting for the premium version.

Quillbot Free allows users to paraphrase 150 words with two writing modes only, which is one of the drawbacks of the free version.

Quillbot Premium

In Quillbot Premium, you basically unlock all the additional benefits like a summarizer tool, freeze words, compare different modes side by side, and paraphrase unlimited words. 

Quillbot Pricing

Isn’t that good news? Quillbot Premium is a writing tool that is on a budget. The premium version can be bought in three subscription modules. Here is a quick pricing breakdown for Quillbot.

Monthly $9.95/month

I obviously settled for the mid-ground, but ultimately, the annual subscription turns out to be the best purchase since you are getting access to all the features in Quillbot for a whole year at a discounted price.

Unlike other competitors, Quillbot is stepping ahead and offering users the choice of pausing their subscription if they are not using it on a regular basis. That is such a thoughtful feature!

NOTE: Quillbot offers a 100% money-back guarantee which can be requested within the first 3 days of purchase..

Grammarly Free

Like Quillbot, Grammarly also provides a standard version that can be accessed for free with no hidden charges. In Grammarly Free, the features include changing the preferred language, spelling correction, tone detection, and punctuation errors.

Grammarly Free can be integrated via MS Word, Google Docs, or even a Chrome Extension. Even the official Grammarly website allows you to proofread your content within a few minutes.

Since the features in Grammarly Free might be limited, it is a better idea to upgrade to Grammarly Premium if you need powerful features like a plagiarism checker.
