When I first began my writing journey, grammar checkers were stern old ladies who did everything by hand and were prone to making as many mistakes as was I.

Luckily, things have changed for the better, though I wish I could have had such a program at my disposal when I wrote my novel, Iron Dogs. It would have made my life so much easier!

Quillbot is perfect for students, professionals, bloggers, authors, screenwriters, and anyone who wants to improve their writing skills.

Let’s look more into Quillbot’s features, benefits, cost, and my own experiences using the Quillbot plagiarism checker, summarizer tool, and grammar checking tool!

Quillbot Pros and Cons

As everyone knows, grammar is essential. It’s the difference between sounding like an educated professional and sounding like, well, someone who doesn’t know the difference between ‘your’ and ‘you’re’.

In today’s fast-paced world, ensuring that our communications are clear and error-free is more important than ever. That’s where Quillbot is amazing.

Quillbot is a grammar checker that can help you to spot errors in your writing and correct them quickly and easily. But is Quillbot the right choice for you?

Let’s take a look at some of the pros and cons of using Quillbot as your go-to grammar checker.

What’s Great About Quillbot

  • Quillbot offers a free version, letting you try out the software before you upgrade to the premium version.
  • Most people seem to find that Quillbot is a true time-saver!
  • It works very well to correct spelling, punctuation, and grammar errors for non-native speakers of English.
  • Because it’s powered by artificial intelligence, Quillbot gets smarter the more you use it. So over time, it will become even better at spotting and correcting errors in your writing.

What’s Not Great About Quillbot

  • Some people find Quillbot’s corrections overly aggressive; however, you can easily dismiss changes you don’t want to make.
  • Quillbot isn’t always 100% accurate (this is the case for all AI-assisted programs – you, as the human, still need to double-check everything!).
  • The plagiarism checker is reported to be not 100% perfect – you might want to use a separate checker.
  • Some people have found that the software can be glitchy (I had no problems during my experience with Quillbot).

My Personal Experience with Quillbot

Being a blogger as well as a writer, I put this blog post into the Quillbot grammar checker to see how well it would work as a grammar tool. And was I ever pleased! I found Quillbot to be a fantastic budget-friendly writing assistant and grammar-checking tool.

First, I enjoyed watching Quillbot’s proofreading tools scan my document, looking for grammar errors. It counted the errors as it scanned, and I had a good overview of the work still needed when it had finished scanning!

I ran the same blog post through both Quillbot and Grammarly and was pleased to see that there were quite a few differences. While they found many of the same errors, Quillbot seemed to be a bit more thorough. I didn’t agree with some of the changes, but it was easy just to ignore the suggestion.

One issue I had with the software is that I decided to check out the co-writing tools in the middle of fixing my grammatical errors, and when I returned to the grammar checker, the text I had been working on was gone! So, just do one thing at a time, I guess!

Here’s what happened when I entered some text from a blog post on writing great characters in a story:

Quillbot Summarizer Example

Here’s what Quillbot did when I added the same text into the paraphraser too. You can see that it kept the same approximate number of words as the original text (as opposed to the summarizer, which condensed the text a lot):

Quillbot Paraphraser example

To check the spelling and grammar checker, I added the same text into the grammar check function (I did change the text slightly to add in some mistakes, to see if the program would find them). Here’s what it did (and yes, it found all the errors!):

Quillbot grammar check example

To check the translator function, I added the same text and asked Quillbot to translate it to Spanish! Take a look here:

Quillbot translator example

All in all, I am very happy with what Quillbot can do to help with my writing, and I love that it has a free version! I’d say that Quillbot is well worth checking out, if you are a writer of any kind.

3. Hemingway

When it comes to grammar checkers, there is plenty of fish in the sea. But if you’re looking for an alternative to Quillbot, Hemingway is a great option.

Named after Ernest Hemingway, this app is designed to help you write more concisely and clearly. It highlights adverbs, passive voice, and complex phrases in your writing.

Hemingway also makes it easy to see how many words you’ve used in a sentence, so you can make sure your writing is as concise as possible.

And like Quillbot, Hemingway can be free to use (for a limited number of words and with limited features). So if you’re looking for a change of scenery, give Hemingway a try.

4. Google Docs

Google Docs is a free, web-based word-processing application from Google. It allows users to create and edit documents online while collaborating in real-time with other users.

Google Docs also has a built-in grammar checker that can be used to identify and correct errors in your writing. While the grammar checker is not as comprehensive as Quillbot, it can still help catch simple mistakes.

In addition, Google Docs offers some other features that Quillbot does not, such as the ability to insert images and videos, create tables and charts, and add comments and notes.

As a result, Google Docs may be a better option for those who need collaboration tools and visual capabilities and are less concerned with spelling and grammar checking.
