The Best Grammar Checker Apps – Overview

In our opinion, Grammarly is the best grammar checker out there, but it’s not always the best fit for every writer. That’s why I’m going to walk you through other best grammar checkers so that you can find one that’s just right for your needs.

So, these are the best grammar checkers we’ve rounded up. We will get to them in a moment but before then let’s find out some basic information on Grammar checkers including the things to look out for when you decide to choose one.

What Is A Grammar Checker Tool?

Just as the name implies, a grammar checker detects your writing for grammar mistakes and offers suggestions on how to fix them. So, it is not just a grammar checker but a grammar “corrector”.

So, basically, a Grammar checker is a computer program that detects errors in written text. It can detect typos, misspellings, incorrect punctuation, and other common mistakes. Many grammar checkers also offer suggestions on how to correct the errors they find, helping you improve your writing and avoid making similar mistakes in the future.

What Are The Categories of Grammar Checkers?

Grammar checkers come in a variety of forms, from free online tools to more advanced software packages. Here are some of the most popular types:

  • Word Processing Programs: Many word processors, such as Microsoft Word and Apple Pages, have built-in grammar-checking features that can help you spot mistakes as you type them.
  • Online Grammar Checkers: There are a variety of free online grammar checkers available, such as Grammarly and Ginger. These tools can help you identify mistakes quickly and easily.
  • Desktop Software: Standalone programs such as WhiteSmoke offer more advanced features, including detailed explanations of errors and suggestions on how to fix them.
  • Mobile Apps: There are a number of apps available for smartphones and tablets that can help you spot mistakes as you write. Apps like Grammarly Keyboard and Ginger Page offer grammar-checking capabilities on mobile devices.
  • Cloud-Based Solutions: Some companies offer cloud-based solutions that allow you to access your grammar checker from any device, even when you’re away from home.

How To Choose the Best Grammar Checker Software

Choosing the right grammar checker software can be a challenge. There are so many different options out there, and it’s hard to know which one is right for you. Here are some of the things you’ll want to consider when choosing the best grammar checker software:

  • Accuracy: Look for a grammar checker that has been designed to accurately detect errors in grammar, spelling, and punctuation, and suggest corrections
  • User Interface: Make sure the interface is user-friendly and easy to understand.
  • Deep Grammar Analysis: It should offer deep analysis of your writing, such as identifying sentence structure issues or common problems with language use.
  • Cost: Consider the cost of the grammar checker – is it suitable for your budget?
  • Capabilities: Does the grammar checker offer features suited to your needs? For example, if you require plagiarism detection, then ensure this is included in the package you choose.
  • Compatibility: Ensure that the grammar checker is compatible with your computer, web browser, or other devices. 
  • Customization Options: Some grammar checkers allow you to customize settings and preferences so that it can better suit your writing style or the type of document you’re working on.
  • Support: Check what kind of support services are available should you need help using the tool or making changes to it down the line.

Do You Need A Grammar Checker Tool In Modern Writing?

A grammar checker is an important tool in modern writing. Even with the rise of pop culture text messaging and social media, grammar rules are still needed for producing error-free texts. And so while casual writers may find it not all that important, you’ll still need it to spot typos and other errors that could otherwise go unnoticed.

It is even more important for writers who write professionally. You don’t want to be embarrassed by errors or typos that may damage your reputation, so having a grammar checker is a mandatory asset for you. Even the best writers make mistakes, and a grammar checker can help you catch them.

Imagine having to deal with the following mistakes which are pretty common in writing:

1. Misused Words: Using a word incorrectly, such as using “affect” instead of “effect” and vice versa.

👎 Wrong: “Taking Soda may effect your health

👍 Correct: Taking soda may affect your health

2. Dangling Modifiers: Having a modifier that does not refer clearly to any word in the sentence, and creates ambiguity about what it is describing.

For example:

👎 Wrong:Walking to school, the flowers were in bloom.”

👍 Correct: I walked to school and the flowers were in bloom.”

In the first case (wrong example), it means the flowers doing the walking. It should actually be “I walked to school and the flowers were in bloom.”

3. Comma Splices: Incorrectly using a comma instead of a semicolon when connecting two independent clauses. An example of this would be:

👎 Wrong: “I like ice cream, it is my favorite dessert.”

👍 Correct: “I like ice cream; it is my favorite dessert.”

4. Misplaced Modifiers: Placing a modifier in the wrong part of a sentence, leading to confusion about what it is referring to. For instance, writing:

👎 Wrong: “He ate pizza quickly with pepperoni.”

👍 Correct: “He quickly ate pizza with pepperoni.”

Writing “He ate pizza quickly with pepperoni” could mean either he ate the pizza quickly, or he ate it with pepperoni. It should be “He quickly ate pizza with pepperoni.” These kinds of mistakes are common but they can be avoided with the help of a grammar checker. It not just helps you to save time but also makes sure that your writing is error-free and up to standard.

Knowing these kinds of mistakes, how can you choose the best tool to spot these errors and more? Let’s find out next.

Now, let’s dive in to explore the best grammar checker tools available.

Source: Ginger

Ginger Software does more than only check the spelling of words against dictionaries. The features that I like the most are the spelling and grammar checks, as well as the writing tools that give definitions, sentence rephrasing, and language translations. Tools come in handy if you’re stuck and in need of advice. Ginger provides audio editing so that you may listen for mistakes. I’ve used it to draft ebooks, website page copy, and blog entries.


Ginger costs $19.99 a month, but as you can see in the image, they often provide discounts. Additionally, the free version offers plenty of benefits, and you can use it for a very long period.

What I like/Don’t like About Ginger

What I likeWhat I don’t like
– Gives quick tips for spelling
– Only at Ginger is a complimentary rephrasing service offered
– It is more accessible because of in-line recommendations
– Inappropriate for social media
– Ginger is not situational sensitive. Its advice seems a little too official in the email

Generally speaking, Ginger is a fantastic app for the majority of writers who need an app to hold them by hand, direct them, and offer suggestions while writing. It’s inexpensive, offers good spelling and grammatical checks (though the advanced reporting isn’t fantastic), and is simple to use.

It is compatible with operating systems, and web browsers (Safari, Edge, and Chrome). So this grammar checker will function well on any of these.

3. ProWritingAid

Best For Novelists

ProWritingAid will undoubtedly be of great use to both experienced writers and aspiring authors. Contextual problems, copied information, and grammatical and spelling faults are all detected by this app. After that, ProWritingAid tidies everything up. Additionally, it looks for repetition, ambiguous language, and variations in sentence length.

Key Features

  • It has integrated spelling and grammar checks.
  • Goes above and beyond to accommodate each writer’s unique writing style
  • Numerous connectors also increase the application’s capabilities to help prevent formatting errors.

Not only are grammar and spelling supported by ProWritingAid, but you are also able to choose genres. It enables you to assess your writing in comparison to one of your genre’s best-selling authors.

It also assists you in correcting sentence structure, identifying overused adjectives and adverbs, pacing, displaying a graph of sentence length, and much more. It’s like carrying an editor around with you 🙂 And they continue to upgrade the product.


ProWritingAid has a $20 monthly fee and a free version, although the free version lacks the capabilities that the majority of professional writers need.

What I like/Don’t like About ProWritingAid

What I likeWhat I don’t like
– You get access to all of the grammar and vocabulary correction options

– The ProWritingAid engine has the most recent and updated English lexicon available

– ProWritingAid’s user interface is simple, quick, and light overall

– A lifetime deal option is available from ProWritingAid

ProWritingAid sometimes experiences lags

My experience Using Reverso

Result output from reverso tool showing no mistakes detected in the content
Source: Reverso

For urgent translations, Reverso is the translator I choose to use above any other. I typically use it for translations between English, French, and Spanish. The app’s ability to provide you with several meanings for a term when there may not always be an exact match is something I admire. “Le dommage”, for instance, is a French term that may imply “hurt” or “damage,” as well as other things to help you understand the full usage of the phrase.


Reverso is free to use for a limited time before charging according to the number of words you translate. The cost per month for the Premium edition is $9.99.

What I like/Don’t like About Reverso

What I likeWhat I don’t like

I like the fact that Hemingway helps me to improve my sentence structure and reduce fluff. It also grades my reading and helps me to know if I am still within the required range or off. I also like the tab that is on the right that shows you your readability, the number of adverbs, if you have used passive voices, and the number of difficult sentences.


This is one of the best grammar checkers that are available for no cost at all. And the Hemingway App is available for just $19.99. Unlike similar editing services, there are no ongoing fees.

What I like/Don’t like About Hemingway

What I likeWhat I don’t like
– Helps you become a better writer
– Simple to implement

It’s one of the best ideas I’ve ever thought of. It’s not magic, but it saved me just too much time. I’m thrilled. I bought the premium version since it gives me more re-writing choices. This is for non-native English writers. Quillbot accepts what you enter. Thus, you must constantly verify to make sure the concepts flow properly. This review was written by Quillbot.


QuillBot is far more reasonable than other premium software, so even those without a budget may get it.

  • $9.95/month for a monthly plan
  • $39.95 semi-annually, payable every six months

It just requires that you open it, copy and paste your content, click “Check,” and then begin editing.

What I like/Don’t like About Scribens

What I likeWhat I don’t like

WhiteSmoke is one of the best multi-purpose grammar checker tools currently available. The style checker and the explanation of mistakes are some of its best features. It is one of the most practical alternatives to the available grammar checkers at the moment.


Does not have a free trial. However, compared to many other writing editors, WhiteSmoke is substantially less expensive.

  • WhiteSmoke Web – $5.00 per month.
  • WhiteSmoke Premium – $6.66 per month.

9. SpellCheckPlus

Best for Google Docs

The web-based grammar and spelling checker known as SpellCheckPlus makes it possible for students of the English language to examine their own work for spelling and grammatical problems.

My experience Using SpellCheckPlus

Since it provides a grammatical check for a very low monthly charge, SpellCheckPlus is a software that I have used for about six months. And I’ve come to realize that it is a very vital tool for book authors. New writers and users can take advantage of a five-day free trial.


There are two versions of SpellCheckPlus: a free and a paid one. The free version of the application has a 2000-character cap limit. The premium version, SpellCheckPlus Pro costs $15.99 per year.

SpellCheckPlus Pros And Cons

SpellCheckPlus Pros

  • Categories errors into a summary
  • Explanations of grammar
  • Mistake summary

SpellCheckPlus Cons

In contrast to other tools, I must say, Wordtune operates naturally. Even after revision of a text, it preserves the meaning. It is ideal for academic writing, such as research papers and reviews, since there really is no need to alter scientific terminology or the contexts in which they’re used.


Wordtune is free but to use its Chrome extension, you’ll have to get the premium version. Additionally, the new Microsoft Word add-on and the online editor are available. The premium costs $9.99 per month.

What I like/Don’t like About WordTune

What I like:What I don’t like
– Free program is offered
– Simple to use
– Helps you clarify your message
– Excellent AI rewriting editor
– Not accessible on mobile
– There is no desktop application

I believe that the majority of writers and other professionals who regularly send emails and other types of communication can benefit from using this tool. It’s undoubtedly a crutch that even authors with years of experience sometimes employ. However, I would only use it if I was really stuck, and no way to navigate out of it.
