The 13 Best Free Grammar Check And Grammar Corrector Apps

The Best Free Grammar Checkers

We are all writing so much now and for so many different reasons. It doesn’t matter what level your writing skills are.

An online tool is the easiest way to correct your grammar, spelling and punctuation for any form of writing, from blog posts to books.

Word processors such as Microsoft Word do a very poor job.

They can only perform a simple spell check and rarely find anything more than the most basic grammatical errors. They do not examine sentence structures.



You have a lot of grammar apps to help you

There are many online grammar checking tools that do a much better job of offering you suggested corrections.

Some tools even give you an explanation or examples of grammatical rules to help you correct your texts.

If the English language is not your mother tongue, using online tools to check your English grammar and find any spelling mistakes in your writing is always good practice.

For students, a quick online check is the best way to help you correct your writing assignments, papers and essays.

You haven’t got money to burn, so using a free online grammar checker is one of the most practical ways to improve your writing skills.

All of the grammar correction and spell checker tools listed below are available for free or have a free version. Some are available as mobile apps too.

If you are an author, content writer or pro blogger, you might need to consider a premium tool at some point that will better suit your workload.

So what are your choices for a free grammar check tool to help you enhance your writing?


1. Grammarly


There is no doubt that Grammarly is one of the most popular grammar tools.

Since it began in 2009, it has become a favourite app for writers. For many, it is the best English grammar checker of them all.

It has so many ways to check your writing. You can use the editor, connect to Word and Google Docs as well as the different browser extensions. There is also an iOS app.

If you are looking for an advanced level grammar tool, this is it. Grammarly can check your text for run-on sentences, incorrect pronouns and misused words.


It is great for synonyms and gives you many suggestions to improve your writing.

I use Grammarly every day for my online and blog writing. So I can vouch for how useful, accurate and effective it is. 

It is one of the best grammar checker tools you can have in your writing toolbox.

2. Prowritingaid


Prowritingaid is one of my favourite writing checkers for long-form writing.

Any tool that can find your common writing mistakes and offers you quick and easy corrections is going to help you make your writing so much better.

You can use Prowritingaid for free to check your writing with its Chrome extension. Then you’ll have peace of mind that what you write will be as error-free as possible.

It’s a great free tool for checking your online writing for blogs post or articles and social media posts. It’s also ideal for students who need a little help with improving their assignments or essays.

Are you are an author or long-form content writer? Prowritingaid offers so many different ways to analyse your long texts and documents. It includes over twenty reports that you can use to analyse your text or manuscript in depth.

It does far, far more than simply giving you a grammar suggestion list.

I use it all the time to find ways to improve my writing because it is without a doubt, the best checking tool for long-form writing.

What I like most is that I can really investigate my sentence patterns and structure and find better ways to make my writing much clearer and more effective.

It works with both Windows and Mac, with Word, Google Docs, Scrivener and has a free Chrome extension.

3. Ginger Grammar Checker


Ginger spelling and grammar is so simple and easy to use. Ginger Grammar has been around for a long time now and is a favourite of many writers.

It will find your spelling and grammar errors so you can quickly fix them with a single click.

With the browser extension, you can correct your mistakes anywhere. One of the best features of Ginger is the sentence checker that uses contextual spelling correction.

It will highlight your spelling errors based on the context of your sentence such as mistakes including bare and bear, to and too and many other common homonyms. Just let Ginger spell the word right.

Ginger software is a robust grammar checker app that is a very accurate sentence, spelling and grammar checker. It is perfect for working writers and students alike.


4. Hemingway Editor

Hemingway App


This is one of my favourite free online grammar check tools. The Hemingway App is just so easy and simple to use.

All you have to do is go to the website and paste your text into the editor. I call it my quick fix passive killer.

If you have a habit of using the passive voice too often, this grammar checker app will certainly be for you.

It will find your passive sentences in a flash. Then you can change your text to use much more direct active sentences.

5. Language Tool

Language Tool

Language Tool has one very big advantage. You can check more languages than English.

The free version offers a generous 20,000 character limit as well as access to check your German grammar too.

You can also get a Chrome extension for free.

It is very much worth a look.


6. Gradeproof


Gradeproof is an online grammar and spelling checker.

It works with Google Docs, Microsoft Word, iOS, and on the web as a browser extension. Like similar grammar checkers, there is a free and a premium option.

With the free version, you get spelling check tools and grammar checking plus a custom dictionary.

If you only need the basics in a grammar checker app, it could be a good choice for you.


7. After The Deadline

After the Deadline

What makes After The Deadline different is that it is free to use open-source software.

It is available to download for Chrome, Firefox, WordPress and Open Office as well as other applications.

I haven’t tried this software, so I can’t make any recommendations about how well it finds grammar mistakes. 

But if you are looking for a truly free solution, this one might be for you.


8. Grammar Lookup

Unlike many other free apps, with Grammar Lookup, there seems to be no limit on the number of words you can check.

I pasted 3,000 words from a book manuscript into the text box, and the app started checking for grammar, spelling and punctuation errors.

If you’re looking for a totally free grammar app with a generous word limit, this one is well worth trying.


9. Grammar Check

Grammar Check

Another good free grammar site. Just paste your text into the Grammar Check editor and that’s it.

Nothing fancy, but if all you want to find are basic grammar mistakes, this app will work fine for you.


10. Online Correction

Another easy to use online application. When I tested Online Correction, it found some spelling and grammar errors as well as some typographical points.

While it is an advertising-supported tool, it is not bad at all. I pasted around 3,000 words which the tool analysed very quickly.


11. Spell Checker Plus


Another advertising-supported tool. But Spell Check Plus handled my 3,000-word text with ease.

It did a decent job of finding spelling error corrections and some punctuation errors.

Useful for a quick check of a short article or essay for students.


12. Paper Rater

Paper Rater

Paper Rater is definitely aimed at students.

I had to cut back my 3,000-word text to around 1,500 words as there is a word limit restriction on the free version.

However, it produced a detailed report, but it was a little slow compared to other similar apps.


13. Reverso


Reverso is best known as an online translator for people learning English.

However, it has a grammar and spellchecker as well.

It is quite basic though, with a very small limit of only 600 characters. Not enough to check very much at all apart from perhaps short social media posts.



You want the best grammar checker, free, of course. But there is always a price that you pay for free.

All of these apps above are free to use. Some are cut-down and restricted versions of a premium app and others are heavily advertising supported.

Choosing the best free grammar checker for your needs will mean that you will have to check how well each one performs for you.

For students, there are many apps that can help your writing as long as you can ignore the ads. They might prove to be exactly what you are looking for in a writing checker.

Look for apps that allow you a reasonable and fair word limit though. If you are restricted to less than 1,000 words, it will not help you a great deal.

For writers, bloggers and authors though, I would have to say from experience that Grammarly, Prowritingaid and Ginger Grammar are by far the best three choices.

The choice between the free and paid versions of the three will depend on how much writing you do, and if you are monetising your writing.

For professional online writers and also authors, you might need to consider a premium version at some point in time.

But free or paid, there are plenty of options for you to choose from if you are looking for a grammar checker app or an online writing tool.
