What Is Quillbot?

Quillbot is an all-in-one writing solution that enables students, bloggers, and professionals to quickly paraphrase, check grammar, and summarize the content. It also has a citation creator where you can easily generate citations for both – webpages and books. 

Quillbot is a web-based platform, and you don’t have to download it to use it. In fact, you can start using Quillbot even without registration. This tool is mostly used for its paraphrasing feature that allows you to quickly reword and restructure the text. It supports different paraphrasing modes and you can automatically rewrite articles in 6 different styles.

The reason why Quillbot is so popular is that offers a lot of value for free. While it does have a premium version, you can get a lot of value from its free version alone.

How Does QuillBot Work?

Quillbot is not difficult to use but it still requires some basic learning. Here we will go through each feature of this platform and demonstrate how does everything works. We will cover paraphraser, summarizer, citation generator, and grammar checker.

Paraphraser Tool:

There are 6 paraphrasing modes on Quillbot. The free version of the platform will only let you rewrite on 2 modes and will limit the character number up to 700 – that’s approximately 110-150 words. With the free version, you are also limited to adjusting the synonym accuracy.

Anyway, we have a premium version of this software, so we can show how everything works without limitations. We are also going to test the quality of rewriting and compare the outcome of different paraphrasing modes – Standard, Fluency, Creative, Formal, Shorten, and Expand.

Let’s have a look at all paraphrasing modes and see how they are different:

Quillbot’s Paraphrasing Modes:

The text on the left side is the original text, and the text on the right side represents the paraphrased text:

Standard: This is a default mode. It keeps the balance between changing the input and keeping the original meaning in order to maintain the most natural outcome.

Standard mode

Fluency: This option guarantees that the content is free of grammatical errors and sounds authentic. The least text modifications are done in Fluency mode, and it ensures that the meaning remains the same. Synonyms are set to the lowest level possible.

Creative: This option changes the text the most, giving it a completely new appearance and tone. This mode may affect the meaning.

Formal: This mode adjusts the text to make it look and sound more professional. This is an excellent choice for academic or business writing.

Formal Quillbot Mode

Shorten: This option reduces the length of the text while keeping the original meaning. This helps to minimize the word count.

Expand: This mode prolongs the text as much as possible by adding extra words. This is useful when you need to increase your total word count.

Other Paraphraser Features:

Despite the automatic rewrite function, Quillbot is also capable of manually altering the Spintax. In case you don’t like automatically picked synonyms for certain words, or paraphrased sentences, you can manually change them within few mouse clicks.

To change the word you don’t like, simply click on it, and choose a synonym from the options:

Manual Word Rewrite
Rewrite words manually

And to do the same, but for the sentences, click on any sentence that you’d like to change and click on the feather icon. This will allow you to rewrite that sentence in different paraphrasing modes:

Manual Sentence Rewrite

Synonym Tool:

Synonym Tool allows you to adjust the number of words you want to replace with synonyms. You can adjust this setting by using the slider at the top of the input and output boxes. The more words you change with synonyms, the more you will possibly alter the meaning.

synonym tool quillbot

There are 4 synonym settings available: the 1st setting will replace the least amount of words, and the 4th will replace the most words. However, the maximum synonym setting is only available to Premium users.

Freeze Words (Premium):

Freeze Words is another great feature that allows you to protect certain words from rewriting. To use this function hit the snowflake icon located in the input box, and a tiny window will open. There you can type in all the words and phrases that you want the paraphraser to ignore, and separate them with a comma.

Compare Modes (Premium):

This is a handy feature available to Premium users. It allows you to compare individual sentences paraphrased in different Quillbot modes. To use this feature, just select the sentence in the input box that you want to compare, and hit the Compare Modes icon.

compare modes quillbot

Then, a sidebar will open, and you will be able to see the variations of that sentence in each mode. There you will be able to select the sentence variation that you’d like to replace or you can keep the original. From there you will also be able to adjust the synonym quantity.

Summarizer is another powerful feature of Quillbot, which is completely free to use. This tool allows you to condense big articles or chunks of information into a manageable paragraph or a list of the most essential bullet points of the text.

To use the summarizer, start by selecting a summary type. You can either summarize by the Key Sentences or Paragraphs.

Then start typing, pasting, or uploading the text you’d want to have summarized. Select the multiple or main Keyword to enhance your summary, and hit the “Summarize” button. Then, summary or key sentences will show up once your content has been processed.

Here’s how a summary by the Paragraph looks like:

And here’s an example of Key Sentences summary:

Also, note that you can adjust the summary length, and paraphrase it once you are happy with the results.

Citation Generator:

Quillbot allows you to quickly and easily generate citations for essays, presentations, and documents. This feature also comes completely for free, and everyone can access it.

You can either citate a book or a website, and you can do it in three different styles – APA Citation (American Psychological Association), MLA Format (Modern Language Association), and Chicago Style Citation.

To generate citations, paste an URL of a website, or search for a book that you want to citate. Then, select the citation style, and the Quillbot will quickly generate the citations.

Once you have your citation list, you can export and download them in a Word file.

Grammar Checker:

Lastly, there is a lovely Grammar Checker tool available to all users for free. It checks for correct grammar, spelling, and punctuation. It also allows you to correct multiple grammatical errors within one click.

The Quillbot’s extension supports this tool, so you can use a grammar checker from your Chrome browser, Microsoft Word, or Google Documents.

Pros & Cons:

Like any other writing tool, Quillbot has some pros and cons. After heavily testing and using this platform for a while, we have found some distinctive positives and negatives. Here’s exactly what we found:

What’s Good:

quillbot pros

Web-based: This platform is entirely based online, and you can access it from any device. Whereas similar tools like Chimp Rewriter only support the Desktop version, and you are limited to 2 devices.

Easy to use: Quillbot offers a clean and easy-to-use interface that even a complete beginner could understand. In case, you are struggling with something, it has an informative Help Centre where you can find guides on every feature of this tool.

Free value: Quillbot gives out a lot for free. You don’t even need to register to use the paraphraser, grammar checker, summarizer, or citation generator. However, some of the advanced features are limited and require upgrading to Premium.

All in one: The platform offers an all-in-one writing solution for students, bloggers, writers, and other professionals. Here you can find everything you need to create a perfect piece of content.

Affordable – Having in mind that the vast majority of Quillbot’s features are free, we can definitely call it an affordable solution. And for the Premium, it only charges $7.95 a month, while other paraphrasing tools like Word AI cost $57 per month.

What’s Not So Good:

quillbot cons

The Average Paraphrasing Quality: Compared to other article rewriters, Quillbot could do a better job when automatically rewriting the text. As you can see from the examples shown above, often paraphrased text does not look natural and requires a lot of manual editing.

Limited Pharaphraser Features: As being said, Quillbot performs as an all-in-one writing tool, and does not solely focus on paraphrasing. Compared to other rewriting and paraphrasing tools, Quillbot lacks some essential features, such as Bulk Rewriting, Copyscape Integration, Article Fetching, Image & Video Fetching, List Reordering, API Integrations and many more…

No Copyscape Integration: For bloggers writing blog posts, or students writing essays, it would be useful if the platform was Copyscape integrated, and would display the uniqueness score of each written piece. Unfortunately, Quillbot does not have Copyscape integration.

Limited characters for Paraphrasing: A free version of Quillbot only allows you to paraphrase up to 700 characters, and the Premium up to 10,000 characters at once. Even if you’d upgrade to premium, you wouldn’t be able to rewrite longer articles consisting of more than approximately 2000 words.

No free trial: Although you can test the limited Quillbot’s version at no cost, there is no way how you can test the Premium version without paying. And for the money-back guarantee, you can only claim your money back within 3 days after the purchase, and that’s quite short compared to other article spinner tools that offer 30, or 60 days.

No lifetime membership: You might want to use this tool forever and save yourself time in the long run, but Quillbot does not offer a lifetime membership. The maximum subscription time for this tool is 1 year.

Bottom Line:

For those who want to quickly rewrite, paraphrase, summarize, and check the grammar of the text, Quillbot can be a fantastic option. Quillbot gives you access to most of its features instantly, and you can start using this platform for free.

And if you want to get slightly more out of this tool, like the option to paraphrase a bigger piece of the content or paraphrase on different modes, then you can upgrade to premium for a small monthly fee.

But, if you are looking for an advanced rewriting tool, which is packed with more features, and has a better ability to generate more natural and unique content, then there are better Quillbot alternatives for you.

The Best Quillbot Alternative:

spin rewriter

Spin Rewriter is a web-based rewriting tool that is truly capable to produce 100% natural and unique content in seconds. This platform is entirely based on article rewriting and paraphrasing, and it covers a lot of features that Quillbot doesn’t.

This tool stands out from others because it uses the revolutionary ENL Semantic Spinning Technology, which is based on convolutional neural networks. By that, Spin Rewriter is able to analyze and understand not only the meaning of the entire text, but also the relationships between words, phrases, and sentences.

Compared to Quillbot, Spin Rewriter has the same paraphrasing features, plus a lot more. Here’s what this tool has to offer:

  • Easy to use interface
  • Manual & automatic rewrite
  • Unlimited and fast bulk rewriting
  • Article, image & video fetching
  • The multilevel spinning
  • Side-by-side comparison
  • Keyword protection
  • Copyscape integration
  • Automatic paragraph creation
  • List reordering
  • Many API integrations (including WP)
  • Blog submissions
  • Amazing customer support
  • Lifetime membership
  • Free 5-day trial
  • And more…

Talking about the quality of automatic rewriting, Spin Rewriter can do a better job than Quillbot as it uses more advanced machine learning. Spin Rewriter allows spinning hundreds of articles at a time, and there’s no character or word limit for each article. You can watch this demo video to see how exactly this tool works.

Talking about the pricing, because Spin Rewriter is solely focused on content rewriting and paraphrasing, it may cost you slightly more than Quillbot. However, it offers a lifetime subscription plan and that can save you tons of money if you are willing to use this type of tool forever.

Here’re the pricing plans:

  • Monthly – $47/month
  • Yearly – $77/year (60% off)
  • Lifetime – $497 

Additionally, these guys offer a free 5-day trial, as well as a 30-day money-back guarantee.
