Grammarly, as one of the most popular writing tools, fully deserves its spot on the list.

Its simplicity and the sheer number of features you get makes it an ideal place to start if you’re just beginning your writing tasks, whether for work or school.

Grammarly includes a free version, which is available online for your browser.

It covers all the basics, like grammar, punctuation, and spelling.

The great thing about it is that there is no word count limit regarding how much you can use it, and it integrates right into Chrome.

When you create an account, you select your preferred dialect, and you can then add words to your dictionary.

The dictionary expansion is incredibly helpful if you’re writing a fiction novel.

You can use Grammarly by itself, integrated into the browser, or install it as a part of Microsoft Word.

Grammarly also has a nifty tone detection system.

Your sentences will be evaluated and rated on how they sound to an outsider.

The system is excellent when you want to differentiate between a more formal request or an informal piece.

If you want to step up your writing game, Grammarly Premium has you covered.

Using Premium allows you to get additional functionalities, such as writing tips, consistency checks, and stylistic advice. It also has unlimited plagiarism checks for your articles.

The Premium package costs $29.95 per month, $59.95 per quarter, or $139.95 annually.

If you’re a part of a team, Grammarly offers a great Business option that allows up to 150 people to be in a single group.

If you’ve got a large team, you pay only $12.50 per team member per month.


  • Automatic suggestions on the side
  • Tone detection and clarity checks
  • Browser and MS Word integration, as well as a mobile version


  • The free version can annoy you with advice about Premium functions

ProWritingAid, along with Grammarly, is one of the grammar checker tools with the most options available.

It might look too robust to use at first glance, but don’t worry.

ProWritingAid has the capabilities you need and more.

As a free version, ProWritingAid can integrate with Chrome, allowing it to check your spelling and punctuation as you write anything online.

The web-based checker has a limit of 500 words, though, so you’ll need to split up larger pieces for processing.

ProWritingAid’s most amazing feature is its Premium version.

You can integrate Premium with several apps, such as MS Word, Google Docs, Scrivener, and all major browsers.

Premium allows you to use ProWritingAid on just about anything you write.

When it comes to pure checking capabilities, the checker also provides tips for future writing and compiles reports to see how you’ve improved over time.

It offers interactive information or advice on every error you make.

The Premium version costs $20 per month, or $79.99 if you go for an annual subscription.

ProWritingAid also has a lifetime subscription at $399, which might sound a lot, but it can pay off in the long run.

If you want to add plagiarism checking to ProWritingAid, you’ll need Premium Plus, which costs 20% more than Premium.

If you’re a student, you can also get a 20% discount on ProWritingAid Premium, so definitely consider this option if you’re doing a lot of writing for your school needs.


  • Free version has lots of features
  • Includes reports and plenty of writing advice
  • Discounts for students


  • Can look intimidating with too much advice


If you want to try something a bit different, you can go for Ginger instead.

Ginger offers a flexible tool to check your grammar and spelling for you.

With a free version, you can choose between a 350-word limited web app or an extension for Chrome. In both cases, you get the basic functionality of spellchecking and grammar.

However, there’s a limit to how many checks you can perform monthly, so it’s not very helpful if you do plenty of writing.

However, with a premium version, you can access Microsoft Office integration and an app that works on both Android and iOS.

It doesn’t limit the advice it can dispense and provides plenty more options, such as style choice changes and translating into over 40 languages.

It also includes a trainer to help you improve your writing over time.

Premium version costs $29.98 a month, $149.40 for an annual subscription, or $239.76 if you decide to subscribe for two years.

Note that Ginger doesn’t have a plagiarism-checker included, which might be a deal-breaker for some, but it’s still one of the best grammar checkers available.


  • Mobile, browser, and Office integration
  • Great translation options on the go
  • Provides writing training as a Premium service


  • Very minimal free options
  • No plagiarism checking available

WhiteSmoke includes plenty of options to improve your writing, all based on natural language processing and AI-assisted technology.

It’s a great grammar checker to have.

WhiteSmoke doesn’t have a free option available. Its only free option is quick video tutorials to improve your writing.

However, the next best thing is the Web version, which is compatible with all browsers.

It allows you to check your grammar and spelling quickly and has access to plagiarism options.

It also can translate over 50 languages.

You also get over 100 templates to assist you in designing the perfect article for the task at hand.

The Web version costs $59.95 per year or $124.95 for a three-year subscription.

WhiteSmoke’s Premium version allows for all the grammar-checking capabilities and stylistic advice.

Also, it comes with a button to instantly proofread your work.

It’s compatible with Microsoft Office, Gmail, all browsers, or Windows and macOS.

The Premium package costs $79.95 for a year or $199.95 for a three-year contract.

If you’re working in a team, WhiteSmoke offers a business option, including three computer licenses, with all Premium benefits.

With every purchase, you will receive 500 plagiarism check credits, with the ability to purchase additional credits separately.

Prices include a 50% off discount.


  • Powerful AI-assisted spellchecking
  • Great platform compatibility
  • Plagiarism detection


  • No free version or monthly subscription available

Language Tool

Language Tool is another commonly used tool, which is different from the others already listed.

It’s wholly open-sourced, allowing for some unique features compared to other best grammar checker apps out there.

Language Tool’s focus on simplicity will enable you to work without pausing to check on the tool to make changes for you.

It has a clean and intuitive interface, even if that lacks some of the advanced options other checkers have.

It also allows you to spellcheck in over 20 different languages other than English, such as Russian, French, or German.

The free version of Language Tool allows you to put 20,000 characters into its powerful spellchecker.

However, it doesn’t fix much more than basic grammatical errors.

The Premium version contains more options for every language it supports and allows you to check citation sources, such as ISBNs.

The web version limits 40,000 characters, but the integrated add-on for Microsoft Word has no such limitations.

The Premium package costs $4.92 per month or $50.00 per year.

Publishing houses can also gain access to Language Tool’s API to get customized benefits that suit them.


  • Easy spellcheck for many languages
  • Simple design
  • Access to API for developers and publishing houses


  • Lacks stylistic features of other checkers

Hemingway App

Hemingway is a powerful solution for those who need to simplify and streamline their writing.

Unlike other spellcheckers, it focuses on making the text as readable as possible and will show you the sentences that need to be changed.

Hemingway is entirely free when used as an online app.

However, the focus on simplicity means that there are no options available for stylistic choice or even spellchecking.

You can consider using another spellchecker to augment your work, along with Hemingway.

As such, it is a great, free addition to your writing tools suite.

However, Hemingway doesn’t tell you how to fix any problems it finds.

It just shows sentences that are hard to read, so you will need to adjust everything yourself.

If you want to work offline, Hemingway offers a desktop app for $19.99.


  • Detects long sentences
  • Complexity checks
  • Free


  • Lacks other options
  • Doesn’t fix problems by itself

PaperRater focuses on helping students with their work and provides some great tools to produce an excellent thesis.

PaperRater emphasizes quick spellchecking and readability for the chosen education level.

As such, it’s great if you’re trying to make a piece fit for a particular demographic or are a student yourself.

It will compare with other papers of a similar level and give you suggestions based on that.

PaperRater also does quick plagiarism checking, with a fast search across the internet to make sure you have great work on your screen.

PaperRater only comes in a webpage app; you then insert your content to check.

As such, you will need to write elsewhere.

With the free version, you will get access to 1500 words of content to paste in and check for spelling, grammar, vocabulary, or plagiarism.

You get 50 submissions and ten plagiarism checks per month.

Suppose you want to upgrade to a Premium version. In that case, you get the option of uploading documents for PaperRater to analyze directly.

You also have increased word limits to your submissions, allowing for up to 6,000 words per submission, 200 submissions a month, and 50 plagiarism checks in that period.


  • Fast results
  • Compares to reading level
  • Great for quick plagiarism checks


  • Limited features

We put Scribens on this list for one simple reason. It’s free.

Of course, there’s more to it, as Scribens is a terrific solution for your writing needs.

Scribens efficiently detects the most common grammar and style errors in your texts and provides reasons to make changes.

It also compiles useful statistics for word repetition and suggests alternatives to some overused or overcomplicated words of phrases. Scribens also works in French.

As a web service to import complete texts into and get results back quickly, Scribens allows you to finish all of your work before the checker starts to edit it.

If you want to purchase Premium, you get additional benefits, such as removing ads and improving the size of documents you can upload.

You also get a plugin for MS Word, OpenOffice, or Libre Office.

You can also directly edit texts in your email app, social media, blogs, and other online text fields.

The Premium package costs €5.90 a month, €14.90 for three months, or €39.90 for an annual subscription.


  • Free to use
  • Quickly provides useful statistics
  • Compatible in French

After the Deadline

After the Deadline (or AtD as the developers like to refer to it) is free software that enhances your writing quality quickly.

It is based on open-source AI-assisted designs that work to evaluate what you’re writing and provide intelligent advice to fix it.

It focuses on making your writing more readable, concise, and focused.

It also tracks misused words and typical clichés. It is available on Firefox and Chrome browsers or as a plugin for WordPress blogs and bbPress forums.

You can also integrate it into OpenOffice to be your editing software of choice.

It is less potent than other grammar checkers, but by default, it offers more options for a free upgrade to your writing repertoire.

  • Easily integrated into most common systems
  • Quick and unintrusive


  • Less powerful than paid checkers

Other options you can indulge in are plagiarism checking and inclusivity results.

Writer is available on Browsers as a web extension and integrates with many online services.

For experienced professionals, Writer comes at the cost of $11 per month, but if you’re looking to get Writer for your company, you will need to contact them to make a deal that will give you the best you can get.
