Quillbot Review (2025): Is It A Useful Tool for Authors?

Modern software has functionality that we couldn’t have imagined a couple of decades ago. However, for every genuinely useful tool based on the power of AI, there’s at least one other that fails to deliver the goods. So how does AI paraphrasing and writing tool Quillbot perform and does it live up to its own hype? That’s what this full Quillbot review is set to answer.

This Quillbot review explores exactly what Quillbot is, how it works, and what it’s capable of. We break down how much Quillbot costs and other alternatives that you should know about.

What is Quillbot?

Quillbot is an AI-based writing tool that has several core functionalities. Its primary purpose is as a paraphrasing tool that uses artificial intelligence to reword your writing in a number of different styles. It can also check for grammar issues and plagiarism.

Quillbot was created by Roham Gharegozlou, David Silin, and Luke Lau in 2017. The idea behind Quillbot was to develop a tool that could help people improve their writing by providing suggestions for rephrasing and restructuring sentences.

Quillbot has a very large team compared to many other author software tools out there on the market. 

By itself, this fact is neither good or bad. On the one hand, a larger team suggests a careful end product. On the other, a larger team requires more revenue in order to pay everyone.

One thing that’s reassuring about the Quillbot team, in spite of its large size, is the type of people hired by the organization. Research scientists and linguists make up some of the people working on Quillbot, suggesting it’s a tool that will benefit from the input of experts.

Quillbot Review: Service Offerings

Here are some of the services that Quillbot offers:

Quillbot Paraphrasing Tool

You can either type directly into Quillbot or paste in an existing section of text. It then uses AI to reword your writing. You can specify that Quillbot should make your writing simpler or more formal depending on your needs and the purpose of your writing.

You can use Quillbot through your web browser or integrate it into Word, Google Docs, or as a Chrome extension.

Quillbot Grammar Checker

One of the fastest ways to ensure a reader stops focusing on the message of your writing is to use improper grammar, spelling, or punctuation. Quillbot has a free grammar and punctuation checker tool.

While there’s no doubt this tool is useful, most writers will probably already have a grammar checker solution such as Grammarly or ProWritingAid. It’s hard to imagine there are many people who hear about Quillbot without first having a grammar check solution in place.

Quillbot Plagiarism Checker

Although plagiarism checkers have the most utility in the world of academic writing, that’s by no means their only use. You might want to check that your own writing hasn’t subconsciously used material you’ve read elsewhere. Or, you might have outsourced some written content, such as a blog post for your author website. In such cases, it’s a great idea to make sure the content you’re paying for is actually original.

Quillbot Summarizer

One of the most interesting features in this Quillbot review is the summarizer tool. Every writer knows that the quality of the research they carry out has a huge impact on their final book. This is the case for fiction and nonfiction authors alike.

For example, nonfiction authors need to be true experts in their subject matter. It’s essential to read widely to have a solid grasp of the topic at hand and understand it well enough to offer some kind of unique twist or insight on the body of knowledge currently out there.

Similarly, fiction books can live and die on the level of detail they provide. If you’re writing about a topic or location you’re not personally familiar with, it’s vital to become as familiar with it as possible in order to offer an immersive level of detail for your reader.

How Much Does Quillbot Cost?

If you like the sound of what Quillbot has to offer from this Quillbot review so far, you’ll be excited to learn that it’s available as both a free and paid offering. Here are the differences as well as how much the paid version of Quillbot costs.

The free version of Quillbot allows you to paraphrase up to 125 words, and limits the paraphrasing styles available. You can summarize up to 1200 words of research.

The paid version of Quillbot allows you to paraphrase text of unlimited length. The summarizer tool has a 6000-word limit. You also unlock different paraphrasing styles as well as access to the plagiarism checker. 

If you want to invest in Quillbot, the tool is only available on a subscription basis. You have the following three options:

• Monthly Quillbot subscription for $19.95 a month
• 6-month Quillbot subscription for $79.95 every 6 months
• Annual Quillbot subscription for $99.95

Overall, we honestly feel that the Quillbot subscription cost is expensive and not justified by the functionality on offer. If more benefits for authors are added, perhaps the cost would be more justified. Let’s look at some pros and cons in our Quillbot review next so you can see where we are coming from.

Quillbot Review: Pros and Cons

Now that we’ve explored the functionality behind Quillbot, let’s summarize its key pros and cons from the point of view of an independent author. 

Pros of Quillbot

• Paraphrasing assistance: Quillbot can help users rephrase sentences, which is particularly useful for improving the clarity and readability of writing.
  
• Vocabulary enhancement: It can suggest synonyms and alternative words to improve the richness and variety of vocabulary in a piece of writing.
  
• Grammar and style suggestions: Quillbot can identify and suggest corrections for grammatical errors and help improve the overall style of writing.
  
• Time-saving: Using Quillbot can save time by quickly generating alternative phrasings and suggestions for improvement.
  
• Learning tool: Quillbot can be used as a learning tool to help users understand how to express ideas more effectively and learn from their writing mistakes.

Cons of Quillbot

• Accuracy: While Quillbot is generally accurate, there may be instances where the suggested rephrasings or corrections are not ideal or contextually appropriate.
  
• Over-reliance: There’s a risk that users may become overly reliant on Quillbot and not develop their own writing skills.
  
• Limited context understanding: Quillbot may not always understand the context of the text it is analyzing, which can lead to inaccurate suggestions.
  
• Subscription costs: While there is a free version of Quillbot, some features and advanced functionalities are only available with a subscription, which may be a drawback for some users.
  
• Privacy concerns: There may be concerns about the privacy of the text being processed by Quillbot, especially for sensitive or confidential information.

Who is Quillbot For?

Although Quillbot is an interesting tool that uses AI in an innovative way, we don’t necessarily see it as being ideally suited to the needs of self-published authors. Think about your own writing process and how often you need to have AI paraphrase your work when writing. 

However, that’s not to say that Quillbot is entirely useless for indie authors. We can think of two primary reasons why you might want to check out Quillbot if you’re writing and publishing your own books:

• If you regularly feel the need to rewrite your work, either simplifying it or making it more formal, Quillbot might save you time over having to do this manually. 
  
• If you need to digest large amounts of research, but don’t want to sift through everything manually, the Quillbot summarizer tool might play a helpful role in your process. 

Ultimately, we feel most self-published authors would find better value by investing in a tool such as Grammarly or ProWritingAid, not to mention a dedicated writing environment like Scrivener. However, if you’ve tried those options and still find Quillbot has something different to offer, give it a go and see if it plays a valuable part in your process. 

Other Quillbot Reviews

Now let’s take a look at some Quillbot reviews from users so you can learn more about everyone’s experience with the AI tool.

As you can see in the Quillbot review above, students may find the app extremely helpful when writing papers. Unfortunately, not all Quillbot reviews are so glowing.

It seems like Quillbot reviews are an extremely mixed bag, so think carefully before signing up.

Alternatives to Quillbot

So what else is out there offering similar functions to Quillbot?

Regarding Quillbot’s paraphrasing capabilities, we will almost always advocate for manual paraphrasing. It’s essential to retain your voice and unique style as a writer. If you let AI do the work for you, is it still truly your writing?

If you really want a tool similar to Quillbot, then Wordtune is probably the closest thing.

We also highly recommend using a tool like Grammarly or ProWritingAid. It can help you rewrite your work according to a more formal or straightforward style. The free versions are arguably better than Quillbot. 

Quillbot review: The Final Verdict?

Overall, after our full Quillbot review, we award Quillbot 3 stars. 

We feel that the free version of the tool is interesting and a nice use of AI. 

However, we feel the paid version does not represent the best value for money, and authors are better off looking at options such as Grammarly or ProWritingAid. You can check out our reviews for those writing apps (and more) below:

• Grammarly Review
• ProWritingAid Review
