Do you want to write a better version of your online content? Quillbot is a paraphrasing tool that switches your text to make it unique and better—almost like a thesaurus for complete sentences!

As a bestselling author and content creator, I love programs like this. I tested Quillbot to check it out, and here’s my honest review.

My Quillbot review will discuss the program’s features, who it’s for, and the best alternatives. Keep reading to know whether you should stick to the free version or subscribe to a premium plan.

What is Quillbot?

Quillbot is an online writing assistant that uses artificial intelligence and machine learning to paraphrase sentences. It boasts several tools used by millions of people worldwide who want to improve their writing.

Its name comes from the idea that Quillbot has a requilling or rephrasing functionality. It’s designed to include up to seven modes, so you have many options for rewriting and enhancing your sentences. I thought that was pretty cool!

Quillbot also guarantees you find the ideal tone, language, and style while paraphrasing your work. You have to enter your text on the text box, and the AI will build the best alternative paragraph for you. The program also features the following:

  • Vocabulary enhancements. 
  • AI-powered thesaurus. 
  • Integrations.
  • Plagiarism checker. 
  • Grammar checker.
  • Summarizing tool. 

What are Some Ideal Uses for Quillbot?

Quillbot is ideal for anyone in the following fields.

Search Engine Optimization

If you’re a digital marketer, blogger, or SEO writer, this web-based tool will help you optimize your online content. Quillbot is one of the few powerful content generation tools that paraphrase your text to be more original, engaging, and concise.

Avoiding duplicate content is central to SEO writing. Google automatically lowers your SEO rankings if they find plagiarized works. The Citation Generator and Rephraser will stop you from getting in trouble.

Academic Writing

Another ideal use for Quillbot is academic writing. This isn’t me, but I can see how it’d be great for those who are into that. You can quickly turn around online content from different source materials through the rephraser tool. The academic writing tool offers a vast extent of synonyms that will prevent your work from being flagged as plagiarism.

Quillbot offers in-text and complete citations for these references to ensure your work stays ethical. There’s no more need to consult your style guide when citing sources because the app automatically produces your bibliography.

You also can correct spelling, grammar, and punctuation errors with Quillbot. It’s not as elaborate as Grammarly, in my opinion, but it does the job. 

Media and Journalism

Whether you work in print or digital media, Quillbot will save you lots of time polishing hot topics you’re writing. Depending on the audience preference, it’s a quick and easy way to make your journalistic pieces more conversational, formal, or shorter.

The variety of writing modes allows you to avoid style errors. Whether formal or friendly, Quillbot gives you several choices on how to rephrase your pieces. 

Aside from news articles, you can use Quillbot for press-related materials. You can summarize long bodies of the text so that readers will focus on the essential elements.  

Quillbot Features

Here are the primary tools you’ll discover upon using Quillbot. Some are available on free and premium versions, while others are only for premium subscribers.

Quillbot Paraphraser

Quillbot Paraphraser

Quillbot’s paraphrasing tool is the software’s unique selling point as it rephrases your sentences to guarantee originality. This unique feature lets you adjust or restructure your whole output through its artificial intelligence technology.

The paraphrase is available in seven editing modes. There’s also a default option that appears when you launch the program. Just paste your text on the search bar or upload a document, and Quillbot will modify your content. 

You can also take advantage of Quillbot’s synonym bar, which lets you choose the number of synonyms you want in your document. The more synonyms you allow, the more unique it becomes. However, this may also mean more inaccurately paraphrased text.

I like that you can choose from four points, which start from low to high. The default option sets it on the second dot, except when you’re on Fluency mode. However, the free version only has three levels of synonyms options and two writing modes.

The free version of Quillbot also has a 700-character limit per check compared to the premium plan’s 10,000-character limit. 

Both free and premium versions of the paraphrase are available on Google Docs and Chrome extensions.

Quillbot Summarizer

Quillbot Summarizer

As an all-in-one writing tool, Quillbot also has a summarizer apart from its rewriter tools. This nifty feature shortens entire articles into a summary. Its usage range from essay abstracts of different topics to SEO summaries or meta description. 

You can also use the summarizer to produce email newsletter summaries and shorten some parts of a book. It’s perfect for almost any writing context. 

Two functions operate under Quillbot’s summarizer. First, you can try the Key Sentences mode, which extracts the essential parts of a text into bullet points. The other is a Paragraph mode which shortens the whole text, removes the fluff, and makes it cohesive.

As always, just type your text, upload a document, or copy and paste it. Then select “Summarize.” Quillbot will do the rest for you as you adjust the depth and length of the summary.

If your text exceeds the 10,000 limit, you need to pay for a subscription. The premium plan allows you to summarize an entire document with a 25,000-character limit. 

Quillbot Citation Generator

Quillbot Citation Generator

Quillbot lets you generate a complete citation of any reference for your academic writing. Paraphrasing content is still plagiarism if you don’t give credit to the original author. It’s a great thing that this app also offers citation generation for your convenience.

This service helps university students produce original content as it makes in-text citations in MLA, APA, and Chicago. This feature has additional benefits for those who want to save time from manually creating a reference list.

Quillbot Free will ask you to input the type of reference, author’s name, the title of the work, and year. It will generate the appropriate bibliography, whether you’re citing a book, website, or journal article. 

Grammar Checker

Grammar Checker

Quillbot has a built-in grammar checker that corrects your grammatical errors no matter how many times you commit them. The versatile tool also spots some punctuation and spelling mistakes, helping you save time editing your content. 

It doesn’t have advanced features like Grammarly, but Quillbot is enough to make your writing error-free. Both causal users and professional writers will benefit from the one-click grammar checker.

Use Quillbot’s grammar checker to correct the inaccuracies from the article spinner. It will also help make your final document more natural sounding. If you trust the application enough, you can click on “Fix All Errors” to correct all grammatical mistakes at once.  

Quillbot’s styling options save more writing time, which is an excellent and much-needed feature. Feel free to adjust your text’s alignment, headings, and bullet points.

Quillbot Modes

The online writing assistant is available in seven writing modes or settings when using the paraphrasing tool.

Standard Mode

The first mode you will experience is the Standard mode, the default option when you open Quillbot from the user dashboard. The primary goal of this writing mode is to help you rephrase your statements neutrally.

It will help you change the wording of your text without tweaking the meaning. In most situations, it merely switches the order of your clauses and modifiers. For example, if you write “Because of him, I’m early,” Quillbot’s Standard Mode will suggest, “I’m early because of him.”

It also changes some words into their synonyms. You can adjust the paraphrased sentence to remove errors by increasing or decreasing the synonym bar.  The Standard Mode is available in both Quillbot Premium and Free.

Fluency Mode

The Fluency Mode of Quillbot makes minimal changes to your sentences while still showing accuracy. The AI also smooths your English text by correcting any grammatical errors. However, it doesn’t fix the passive voice and lengthy statements. 

Creative Mode

The Creative Mode is a fantastic assistant tool for writers who want more options for their word choices and sentence structures. Use this premium feature to express your idea in a completely different way. 

However, the Creative Mode makes your writing more vulnerable to grammatical mistakes. Make sure to perform a manual intervention on your piece to correct any errors. 

Formal Mode

The fourth mode that Quillbot offers is the Formal mode, which rephrases your text for the formal setting. It’s ideal for academics, business owners, and government employees who want to make their documents sound professional.

Simple Mode

You can use the Simple Mode if you’re a blogger or social media manager who wants to sound friendly or conversational. Quillbot will rewrite your text to become as readable as possible. It’s perfect for blog articles, landing pages, advertisements, and emails. 

For example, Quillbot may change “ensure” to “make sure” to make your message more understandable. 

Shorten Mode

The Shorten Mode is different from the Simple Mode in that it makes your sentence length smaller. It’s not necessarily concerned with using simple words as it is with conciseness.

This writing mode is similar to the Summarizer. However, the Shorten Mode still keeps all your sentences. Use this feature if your field requires a character or word limit.

Expand Mode

The last Quillbot mode to try is the Expand Mode, the opposite of the Shorten Mode. Instead of shortening your statements, it tries to make them lengthier. 

You might be tempted to use the Expand Mode if you can’t reach the minimum word count required by your professor. Or if you have a specific number of pages for your document. 


Students who write academic papers and employees in corporate settings will love using the built-in thesaurus setting of this article rewriter tool. Quillbot is an excellent tool that offers a wide range of casual synonyms.

The powerful tool also provides the closest synonym of your word, depending on the original context of your work. This thesaurus makes sure there are clear connections between your input and output through cohesion. 

Compare Mode

I made a separate section for Quillbot’s Compare Mode because it’s an exciting feature of the paraphrasing tool that benefits everyone. Thie premium feature allows you to see various phrases and check how they stack up against each other.

Only premium users can enjoy this feature, so they get an overview of different sentence structures to try. They’ll save more time choosing which one sounds better and more natural.  

Can Turnitin Detect Quillbot?

Turnitin cannot detect statements produced by Quillbot because the plagiarism tool’s algorithm cannot spot paraphrasing. They only compare your work against online and offline publications, finding parallel grammatical phrases and patterns.

The plagiarism detector also finds similar sentence structures between the original and duplicate content. What makes Quillbot amazing is its ability to paraphrase pieces of writing very uniquely. 

Some consider Turnitin as a text-matching software rather than a plagiarism checker. The scores only reveal the percentage of writings that match. 

Does Quillbot Have a Plagiarism Checker?

Quillbot finally performs plagiarism checks on your work. 

Plagiarism checkers should be one of the core features of writing tools that aim to make your work original. Thankfully, the program now has one alongside its citation generator and rephraser to help you avoid duplicate content.

The affordable AI-powered paraphrasing tool looks for accidental and intentional plagiarism in your work. Grammarly, QueText, and Turnitin usually highlight copied content and provide links to the primary sources. The same is true for Quillbot.

It even has a feature that lets you know how much your text has changed from the original text.

The Premium version offers 20 pages or about 5000 words per check. If your document exceeds the page number, you need to buy additional pages. This can be expensive for anyone who checks around 20,000 words every week. 

I only recommend Quillbot’s plagiarism tool for academics and essayists. Content publishers can stick to QueText, Scribbr, or Grammarly to scan for duplicate content. 

How to Install Quillbot

Quillbot is available as a web editor on Google Chrome and other web browsers, so there’s no need to install it. But you can install the add-ons or extensions if you do your writing tasks on Google Docs or MS Word. 

Microsoft Word

Quillbot AI is compatible with Word Online and MS Word version 16.0.11629 or newer. Sign in on Word and click the “Insert” tab on the menu bar. Then, choose “Add-ins.”

Once you’ve selected “Add-Ins,” click on the “Office Store” button, and a window will appear. Try searching for Quillbot, and “Add.” 

After Quillbot has finished downloading, return to the “Insert” menu and choose “Quillbot” under “My Add-ins.” Open the application and log in. Then, you are ready to produce your most creative output.

Google Chrome

Installing Quillbot as a browser extension is easy. Search for the app name on the Chrome Web Store and click “Add to Chrome.” This Chrome extension is compatible with other Chromium-based browsers like Vivaldi and Brave. 

How Much Does Quillbot Cost?

Signing up for a premium subscription will increase your word and character limit. You’ll 

enjoy the complete writing modes for your text. The premium version of Qullbot is available in different plans.

The annual plan costs $79.95 a year. I recommend this plan for users who have tried and tested the application.

You can also try the 6-month subscription, which costs $59.99 every six months or $119.98 a year. The total amount is more expensive than the annual plan but is practical for writers on a budget.

The third plan you can try is the monthly subscription for $14.95 or $179.40 a year.

Quillbot Premium offers 100% money-back for users who are not satisfied with their subscription. Note that it’s a 3-day money-back guarantee, so make up your mind as early as possible. 

Quillbot Affiliate Program

  • 30-day cookie window.

Quillbot uses cookies to track your referrals, lasting for 30 days. If the user clicks on your link again, the 30-day tracking starts over. 

Are There Any Good Quillbot Alternatives?

If Quillbot isn’t the right online editor for you, here are three alternatives worth considering.


Grammarly doesn’t have a paraphrasing feature. But there’s a built-in thesaurus, personal dictionary, and plagiarism checker. You can also enjoy the grammar-checking functionality of this AI-powered tool.

It offers more than spelling, grammar, and punctuation corrections. Grammarly gives suggestions on correcting your sentence structure, correcting redundancies, passive voice, and lengthy sentences. Correct the tone, formality, and engagement of your text.

Add unique and personal words to your personal dictionary. This feature will stop the application from flagging the word as misspellings.

These suggestions are so elaborate that it’s almost like a paraphrasing tool. If you want to change a word, highlight it, and Grammarly will offer synonyms. Sometimes, it provides context-specific word alternatives if you’ve already used the term several times. 

Once you’re done editing, you can scan it for duplicate content against billions of other works. The built-in plagiarism checker links plagiarized content to the source so you can cite them properly.

Grammarly also has integrations with Google Chrome, MS Word, and Googe Docs so that you can work across different platforms. Or you can use it as a web editor on your browser.

Jasper AI

Jasper isn’t a direct competitor of Quillbot like Grammarly. However, it’s a famous software that uses GPT-3 technology to manipulate your text. Jasper can also summarize, rephrase, and expand your content to become unique. 

Previously known as Conversion AI or Jarvis, Jasper is one of the best and most similar Quilbot alternatives to try. Paste or type your text, and then the tool will rewrite everything for you. 

The best feature of Jasper is its ability to generate content from scratch. All you need to do is enter hot topics or keywords and let the software do its magic. The result is a human-sounding article that’s either short or long-form. 

The program is perfect for content publishers looking for post ideas or experiencing writer’s block. It’s also for business owners who want to generate sales copy for their services. Use Jasper AI to produce content for titles, introductions, and descriptions.

Jasper is compatible with Surfer SEO, which helps you optimize your content for keyword frequency. Your text automatically gets high rankings while sounding natural. 

Rewriter Tools

If you want a quick and free way to spin your articles, Rewriter Tools can help. It doesn’t have state-of-the-art features like Quillbot, but it’s enough to paraphrase and grammar-check your work. You also don’t need to sign up to use Rewriter Tools.

The web editor has an Article Spinner, which automatically spins your text. Try the Article Rewriter feature if you want more control over the document. There’s also a Paraphrasing Tool that rephrases phrases and sentences.

Rewriter Tools has a grammar checker for your grammatical mistakes and a Word Counter. This feature tells you how many words your text has.

Is Quillbot Worth It?

Quillbot is more than just an article spinner that changes a piece of writing to be unique. It also has a Summarizer, Citation Generator, and Grammar Checker to enhance every aspect of your text. Plus, you can control the number of terms replaced with synonyms.

Use Quillbot Premium if you want to unlock all the seven writing modes. Also, subscribe to the premium version if you want to increase the character limit of the paraphraser.
