scribens screenshot

It’s easy to use with a pleasant interface, and you are not limited by the number of characters, words, or uses.

As the adage goes, “you get what you pay for.”

10. Writer

Writer is an interesting entry in our best grammar checkers list. It uses sophisticated AI technology to allow corporate customers to brand their grammar checker so that all their writers are consistent, using the same phrases, terminology, and voice that the company uses to brand its products and services. You simply define a style guide, and Writer does the rest.

qordoba screenshot

Writer covers the grammar basics by detecting issues with spelling, punctuation, and tone. It also caters to the business crowd by integrating with dozens of platforms making constant suggestions using vocabulary lists that you upload. Some big-name brands use Writer to keep their entire company on target and error-free.

Pricing is pretty good for the individual, only $11/per month using up to 200 custom terms. Enterprise pricing is available but can get expensive with large teams. Writer is a heavy hitter when it comes to grammar checkers. It is reliable, trusted, and full-featured for anyone looking to produce error-free, perfectly branded content.

It’s more of a writing assistant than a full grammar checker but definitely worth checking out.


  • Keeps brand voice consistent across all channels.
  • Multiple teams/multiple style guides.
  • Dozens of helpful integrations.
  • Specialized for companies and branding.
  • Multiple style guides.
  • Full featured.

It streamlines communications and makes sure everyone uses the same responses, voice, tone, and style across all channels.

It isn’t meant to be used as a grammar checker for individuals or students, but it an excellent resource for companies who want to make sure nothing goes out the door that isn’t approved.

12. Zoho Writer

Zoho Writer is another contender in our lineup of best grammar checker software. The program is part of the Zoho suite and is sort of a combo between Google Docs and MS Word.

zoho-writer image

They offer a free version that will suit many users and a paid version for those needing additional features. Unfortunately, if you are looking for the best grammar checker online, Zoho may disappoint you. The program works well on all major browsers, but the problems begin when it comes to using Zoho Writer's built-in grammar check, Zia.

Even though it was designed to catch spelling and grammar mistakes, look for clichés and other common missteps, it fails to catch even the most glaring errors. Users complain of Zia not picking up repeated words, incorrect contractions, and other standard issues.

If you are looking to use Zoho Writer exclusively for a grammar checker, you would be better off using a service like Grammarly instead. When tested side-by-side, the results were overwhelming, and Zoho Writer lost big.


  • Clean, distraction-free interface for writing.
  • Plenty of word-processing features for the pickiest of writers.
  • Works with the Zoho suite of products.

⛔️ CONS:

  • Very poor grammar checker functionality.
  • Unreliable AI system.

  • Effective and reliable.
  • Works in over 20 languages.
  • Completely free; no subscription plan needed.

⛔️ CONS:

  • Free version is limited to 20,000 characters.
  • No plagiarism checker.
  • No style guides.

14. GrammarCheck

If you are looking for the best plagiarism checker on the market, GrammarCheck won't be your first option. GrammarCheck is a bare-bones grammar checking tool online.

grammarcheck image

The website seems like a throwback from about twenty years ago, but it does the job. If you need basic error detection, you can get away using this tool. You basically copy/paste some text into the box and hit the Free Check button. From there, any errors will be underlined in red, and if you hold your cursor over them, you may see a suggestion or two to change it. There are not many frills with this one, and you won't see any complex sentence re-write suggestions or any advanced features. The Deep Check button offers more, but you have to pay for that service.


  • Free version.
  • Simple to use.

⛔️ CONS:

  • Sorely lacking in features.
  • Bare-bones website looks antiquated.
  • No plagiarism features.
  • Feels cheap and scammy.

What is Grammar Checker?

A grammar checker is a software that checks a writing sample for grammatical mistakes, spelling issues, proper punctuation, and sentence structure. Some of the more sophisticated programs also check for style, tone, and syntax to make sure your writing is flawless.

How Do You Use a Grammar Checker?

Grammar software works in different ways. With some grammar checkers like Grammarly, you can copy and paste text into it or upload a file to check it for errors. Sometimes these grammar checkers have plugins for web browsers and email clients, and they continuously check everything you write and suggest corrections when necessary.

Key Features to Look For

When evaluating the best grammar checker to use, you want to consider a few key features. First, you want the grammar checker to be top-notch, catching all your spelling mistakes, suggesting ways to re-word sentences to make them better, fixing your punctuation, and overall evaluating the text for tone, style, and readability.

Why Use a Grammar Checker?

Grammar checkers also help avoid plagiarism, help you learn where you make mistakes, and improve your writing skills.

How To Choose The Best Grammar Checker Software

Ready to pony up the big bucks for a badass grammar checker? Hold your horses. You must weigh your options carefully. Here are some of the things to look out for when choosing a grammar checker.

  • Price
    Many apps allow you to perform an online grammar check for free. But the majority of online checkers follow a subscription model. If you want to use a grammar checker for professional work, it makes sense to pay for one. You get access to more features this way. Pick one that falls within your budget.
  • Accuracy
    You already have a firm grasp of grammar rules, but it does help to have a companion who can pick out the niggling issues that you might miss. Grammar correctors come with different levels of accuracy. Our list below features some of the most accurate in the market.

  • Support
    Does the grammar checker come with reliable customer service? This may not be important if you’re looking for a one-off free grammar check. But if you’re paying for it, you’ll want to know that help is there if you ever need it.

Best Grammar Checker Apps FAQs

How do you check if a sentence is correct or wrong?

It depends on the grammar checker tool. Some programs like Hemingway Editor highlight an incorrect sentence. Grammarly parses out the entire text and shows you where your mistakes lie and how to correct them, even re-writing the sentence to make it more readable.

How can I check my grammar mistakes?

Using one of the best grammar checker apps from our list, you can check grammar mistakes in an email, Word documents, and using a browser plugin, on forms you fill out online.

Using one of these tools, you can upload a document or copy/paste in your raw text. The grammar checker will go through your document line-by-line and identify all the mistakes and issues. Some of these offerings check all your text on the fly as you type.

Which grammar checker is the best?

Especially for writers, the best grammar check app is a personal choice. However, popularity-wise, ProWritingAid has a strong user base and great reviews. It’s continually evolving through updates adding new features, and it checks all the boxes for anyone who writes professionally.

Is Grammar Checker safe to use?

Before you purchase a grammar checker, be sure to read their privacy policy and check into their security protocols. Most of them, like ProWritingAid, and Grammarly vow to keep your information safe and private.

How can I correct my grammar?

Depending on which tool you use, the process may be different. However, with most of them, you will see an alert and highlighted or underlined text that needs correction. The grammar checker may suggest a fix that you can then accept or reject or change it yourself.

Is Grammarly better than Word?

Absolutely! Grammarly is much better than Word, although it is not perfect.

Many writers use Grammarly to fix their commas and other more serious grammatical and spelling issues and then open the same document in Word to do a final check. Sometimes Word will find a couple of issues that even Grammarly missed. It’s best to use more than one to cover all your bases when writing professionally.

Is there any good free English grammar checker?

Yes. Grammarly has a free version you can use online. You can simply copy and paste in your text, and the program will examine it for you and present a list of corrections for you to review. Other programs also have free versions, but not many are as accurate as Grammarly.

What is the best grammar checker software for writers?

There is no one perfect grammar checker for writers. Good writers that strive to produce perfect content consistently use a combination of grammar checkers to be sure they catch every single error, missed comma, typo, and misspelled word.

Is there any website to check grammar?

Yes. Many of these programs are online grammar checkers. Most of them have websites where you can type text directly into a box and review it; you don’t have to download any software or install any apps.

Is a grammar checker accurate?

Again, that depends on the grammar checker you use. Some are more accurate than others. Typically, those that use extensive databases and AI learning are the most reliable.


If you’re looking for the best-in-class grammar checker, then you have to go with Grammarly . It’s a cut above the rest.
