Grammarly is arguably the most popular, and one of the best grammar checker free options around. It launched in 2009 and has more than 20 million users – a true testament to its worth. Both its great writing aid capabilities and many integrations make Grammarly a safe choice.

Overview

Grammarly refers to itself as a writing assistant, and that’s precisely what it is. This software relies on its own database – as well as anonymous data collected from its users – in order to provide grammar and spelling correction while helping writers improve their writing style and readability.

The reason Grammarly is regularly on top of most of the best free online grammar checker lists is the pure quality and accessibility of its writing tools, even in the free plan. This is in part thanks to the data collected from Grammarly’s huge user base, which leads to constant improvements across the board.

Grammarly operates by providing real-time corrections as you type, but you can also paste or import an already existing text into the software to check it for mistakes. Grammarly highlights any serious mistakes in red, while word substitutes and style improvements are marked in green and yellow. The software allows you to immediately make necessary corrections by clicking the highlighted word or sentence. Grammarly is considered the best English grammar checker by many, as it provides a seamless writing experience, quickly and efficiently making corrections as you go, without the need to devote additional time to ironing out the text.

Grammarly is available on just about every platform. It comes as a browser extension, a desktop client for Windows and macOS, and it is available on Android and iOS smartphones as well. When you have the desktop client installed, it integrates with Microsoft Word and Outlook mail, while the browser plug-in handles basically everything you do in-browser. This includes social media, team messaging apps, email, and so on. Furthermore, Grammarly also has a Google Docs plugin, which is why it’s often revered as the best free grammar checker.

As far as the quality of the corrections and suggestions go, Grammarly is top-notch. Thanks to its powerful AI, its corrections – especially the style and readability suggestions – are unmatched by its competitors. One crucial feature that helps Grammarly achieve this status is its ability to select the preferred style or intent of the text.

When you first install the plugin or paste a text into the desktop client, it allows you to select whether you want the text to sound authoritative, informative, casual, and so on. On top of that, Grammarly provides weekly feedback on your writing, and features a plagiarism detector in its paid plans.

Pricing

If you want any of the advanced features that make Grammarly the best online grammar checker – anything beyond spelling and grammar corrections – you’ll need to subscribe to Grammarly Premium.

Readability and vocabulary improvements, a greater selection of writing tones, and the plagiarism detector are all available only if you use the paid version. Unfortunately, Grammarly does not come cheap.

The monthly cost of Grammarly Premium is $29.95. The price is lower if you subscribe quarterly ($19.98/month) or yearly ($11.66/month). Grammarly offers discounts regularly, so keep an eye out for those. It also offers Business plans that cost $12.50 per month/user.

Final Thoughts

Without a doubt, Grammarly holds a deserved place among the best online English grammar checker options. While it does not provide translations or language learning capabilities like some of its competitors, its core writing features are unmatched in quality. However, these features come at a hefty price.

Another robust and powerful grammar and spelling checker, Ginger employs powerful AI and contextual spelling corrections to keep your writing proper, engaging, and professional. Besides its wide plethora of correction features, Ginger also offers translation and language learning options, making for a complete writing improvement package.

Overview

Like most grammar correction software, Ginger is best used as a real-time correction tool that highlights your mistakes as you type. Similarly to Grammarly and other best grammar checker free online options, Ginger highlights your mistakes as you go and provides the correct spelling as an alternative. However, Ginger not only corrects spelling and grammar mistakes, but can completely rewrite sentences or change their word order when needed. 

This is thanks to its Contextual Spelling Correction technology, which takes into account the meaning and intent behind your sentences, offering improvements without altering the essence of the sentence. This patent-pending technology easily handles sentences with multiple mistakes in them, and it only takes one click to make suggested changes.

The Sentence Rephraser is equally valuable. While grammar and spelling corrections are important in any best grammar checker review, they only get you so far. Idioms and phrases are what breathe life into writing, and the Sentence Rephraser does precisely that – changing even grammatically perfect sentences so they sound more natural.

When it comes to language learning capabilities, Ginger’s Personal Trainer has got you covered. This feature analyzes your writing mistakes to pin down the areas you struggle in the most. Ginger then provides you with weekly feedback reports so you can see where you make the most mistakes. Not only do you get weekly reports, but you can also then practice on your own sentences, allowing you to effectively iron out your own mistakes.

Beyond this, Ginger also has a Dictionary and a Translator, which is why it’s always considered among the best free grammar checker options. The Dictionary provides short definitions for words you type into it, allowing you to quickly find out what an unknown word means without needing to Google it. The Translator is self-explanatory and currently covers 40 languages.

Ginger is available as a desktop client for Windows and Mac, as a browser extension for Chrome and Safari, as well as an app for Android and iOS. Furthermore, there’s a Ginger Android keyboard plugin too. Unless you’re using the browser extensions, you’ll mostly have to work from within Ginger to get real-time corrections. The biggest drawback here is the lack of Google Docs integration, but it does integrate with MS Office.

Price

Ginger is one of the best online grammar checker free pieces of software around, with the free plan allowing unlimited grammar and spell-checking, as well as translation. All of the other features are reserved for its paid plans. Ginger currently has a 30% discount going on for its paid plans, making it a great time to subscribe.

A single month subscription costs $20.97, with the monthly price falling off to $7.49 or $6.66 per month if you subscribe for one or two years respectively.

Final Thoughts

While Ginger can go toe-to-toe with most grammar correction software in grammar and spell checking, its Contextual Spelling and English-learning capabilities are where it truly shines.

WhiteSmoke, a candidate for the title of best grammar checker for Mac, combines the strengths of Ginger and Grammarly into one package. It combines grammar checking capabilities with strong translation software, anti-plagiarism detectors, and business correspondence templates, making it a great all-round package for users of all stripes.

Overview

Let’s start off with the core features: grammar and spell checking. WhiteSmoke’s correction features are far from basic. Not only does it correct fundamental grammar and spelling mistakes but it also successfully detects and corrects incomplete sentences, subject-verb disagreements, double negatives, punctuation, and spacing. WhiteSmoke’s feature-rich corrections will guarantee that everything you write is top-notch.

On top of that, WhiteSmoke uses deep error analytics to analyze the structure and length of your sentences. This is what makes it potentially the best essay and grammar checker, as it provides suggestions on the lengths of sentences and the words used, then suggests improvements based upon that data. With it, you can make whole paragraphs or articles significantly better, as it leads to you using richer language and making your text a more engaging read.

WhiteSmoke exists as both a browser extension – available for most commonly-used browsers – and a desktop client. It integrates with most writing platforms and its browser extensions grant you correction capabilities in most online environments. As far as the corrections themselves go, WhiteSmoke goes a step beyond its competitors. Instead of just highlighting your mistakes and offering a correction like many a best grammar checker app, it offers an explanation as to why a particular word or sentence is incorrect, and provides multiple options you can change it to.

If you prefer to learn English the traditional way, and not only through writing, WhiteSmoke also offers comprehensive learning tutorials available in both video and text form. Similarly to Ginger, WhiteSmoke provides word definitions by drawing them from its Thesaurus feature. The software also comes with an anti-plagiarism detector that any teacher, professor, or editor would highly value.

A feature that truly separates WhiteSmoke from other best grammar apps is its correspondence templates. While other grammar check online software offers templates as well, none of them have such a wide selection. The available templates are divided into four groups: medicine, law, business, and personal. On top of all this, WhiteSmoke has a pretty powerful translation tool as well.

Pricing

Since WhiteSmoke is so feature-rich, it’s not surprising that it has no free plans available. There are three different pricing packages you can choose from: Web, Premium, and Business. All are currently available for 50% off regular prices. While this isn’t the best grammar checker software that’s free, it’s still pretty affordable.

The Web plan can only be used as a browser extension and includes the grammar checker, plagiarism detector, and translator. It currently costs $5/month.

The Premium plan gives you access to desktop clients, as well as MS Office and Gmail integration. The price for this package is $6.66/month and it integrates with all writing platforms and offers one-click proofreading.

Lastly, the Business plan costs $11.50/month. It allows the software to be used on three PCs and gives you access to phone support.

Final thoughts

No one can dispute that WhiteSmoke deserves a spot on every best grammar checker and proofreading software list. While it doesn’t offer a free plan, it justifies this move by offering a huge number of robust features.

As the name suggests, ProWritingAid is a grammar checker aimed at professional writers. This bit of software presents a full-rounded package that not only corrects your mistakes, but helps you improve your English knowledge, overcome writer’s block, and more.

Overview

While most grammar software we review focuses on helping everyday writers improve their English writing, ProWritingAid is the only one with a clear focus on people who write for a living. This software aims to provide a high level of automatic editing, greatly reducing the amount of work human editors will have to do afterward.

How does this best free grammar checker online contender do this? Of course, ProWritingAid corrects grammar and spelling mistakes. This also includes punctuation mistakes, double negatives, subject-verb disagreements, and so forth. Additionally, it detects redundancies and terminology and contextual errors.

ProWritingAid also features a plagiarism detector – an invaluable tool for anyone who aims to publish their writing in any form. Furthermore, the software employs a variety of readability improvement features. It improves paragraph structure, detects overused phrases and sentence constructions, and corrects repetitive paragraphs and terminology errors.

While some grammar correction software just highlights your mistakes and offers improvements, ProWritingAid provides whole reports. This is why it’s widely considered to be the best grammar checker for writers. After the program scans your text, it offers a variety of different reports like grammar or style. Each contains thorough explanations of your mistakes and the ways to improve them. While this might be too much for people looking to get quick, short corrections for their emails or social media posts, professional writers will love it.

ProWriting aid also provides synonyms, draws words from the Thesaurus database, and can pull up famous quotes or words that rhyme with the word you’ve highlighted. It even offers tools to help you get over writer’s block by providing plot twists, writing assignments, or giving you inspirational quotes from famous writers.

Like any free best grammar and plagiarism checker, ProWritingAid is available on multiple platforms. You can use it as a browser extension for Chrome or Firefox, download its desktop client for Windows or Mac,or install it as a direct WordPress plugin – a great feature for blog writers. Fiction writers will appreciate the fact that ProWritingAid integrates with Scrivener. It also integrates with Open Office, MS Word, and Google Docs.

Pricing

ProWritingAid has a free plan that provides spelling and grammar checking, without any of the additional features and reports we’ve talked about previously. Furthermore, you can only process up to 500 words in one go.

If you want the full might of this best grammar checker for Word, you’ll have to subscribe to one of the paid plans. The monthly price is $20, but you can get a discount if you subscribe for longer periods. There’s also a lifetime license available for $224. Business plans are available for larger teams or companies – just contact the company’s salespeople to get a quote.

Final Thoughts

ProWritingAid is the optimal choice for professional writers, for whom no other software fully caters to their needs. However, if you just need quick and simple grammar/spelling correction, other providers might be more suitable.

Just as ProWritingAid is built with professional writers in mind, PaperRater is marketed as an ideal tool for high school and college students. If you’re looking for a grammar checker best suited to quickly and efficiently checking your papers for mistakes and possible plagiarism, PaperRater is the software for you.

Overview

PaperRater presents itself as software best used by students wishing to check their term papers before turning them in. Before you start checking your essay, PaperRater will ask for your education level and the type of paper you’re writing in order to provide the appropriate corrections.

This is a great feature, as different papers on different educational levels vary greatly in tone, language, and the precision required by professors. Furthermore, PaperRater compares your paper to essays written by other users of the same educational level in order to provide better corrections.

Unlike many best grammar app and sentence checker options, PaperRater does not provide real-time corrections. Instead, it requires you to copy and paste your paper into the software in order for it to scan the text and provide corrections and improvements. This is a huge drawback compared to competitors like Grammarly, which seamlessly provide corrections as you go. However, due to the marketed purpose of the product, which is checking papers for errors before you turn them in, this is somewhat understandable.

What errors does PaperRater detect? It mostly provides grammar and spelling correction, as well as stylistic improvements based on your sentence length and vocabulary. However, it lacks the contextual analysis many best free grammar and punctuation checker software providers offer.

By comparing your paper to others of the same level in its database, PaperRater can give you an estimate on what grade you’ll receive. Do note that due to the lack of contextual analysis, it can’t detect how well you’ve understood and presented a certain topic – it mostly just bases the grade on style and readability.

Another pitfall of PaperRater is that it does not correct your mistakes automatically. It underlines your mistakes, detects plagiarism, and provides a report, but it’s less than an ideal tool for quickly ironing out grammar mistakes.

Pricing

PaperRater is listed among the best grammar checker for free providers thanks to its generous free plan. It comes with completely free grammar and spelling corrections, writing suggestions, and grade scoring. However, it does limit your paper submissions to a maximum of five pages per submission. You can make 50 monthly submissions, and 10 monthly plagiarism checks.

The paid plan costs $11.21/month or $71.55/year. It allows 20 pages per submission, 200 submissions per month, and 25 monthly plagiarism checks.

Final Thoughts

If you ask yourself “what is the best grammar checker software,” PaperRater probably won’t be the first one to come to mind. Still, it deserves a spot on our best grammar checker list. Thanks to its generous free plan and ease of use, it’s a great tool for students looking to improve the quality of their papers

Methodology

As we’ve mentioned, grammar checking software is now much more than just an online spell-check. There’s a variety of features to look out for when choosing the best grammar checker online, from writing suggestions to translating capabilities and sentence rephrasing. It all depends on your needs, whether you’re a student that needs help with essays or a journalist that needs a press release with perfect grammar. In this section, we’ll go over the features and metrics we found to be the most important when reviewing each software tool.

Grammar Correction and Spell Checking

Grammar correction and spell checking are the core features of any grammar software on the market. In fact, spell checkers have been around for quite a while – you don’t even need specialized software to access them. Microsoft Word, Google Docs, web browsers, and smartphones all have some sort of basic built-in spell checker.

While these are good for catching basic spelling errors, most grammar checker software is much more thorough. The best checkers have a more sophisticated vocabulary database so they can recognize and correct more words. They also tend to be more precise, allowing you to automatically correct misspelled words as you’re typing.

On the other hand, grammar correction is a bit trickier, and here we usually see bigger discrepancies in quality between different software. Grammar checking and other more advanced correction and rephrasing features rely mostly on AI and contextual grammar technology. This goes far beyond correcting spelling errors – it offers word substitutions, rephrasing, and sentence restructuring.

Advanced rephrasing and restructuring features are a hallmark of the best grammar checker software. Grammar checking takes into account the meaning and intent of each sentence and corrects it accordingly. Sentence or essay rewriters on the other hand expand on that and offer better ways to construct your sentences, making them more concise, clear, and well-written. This is useful for both native and non-native speakers alike, as online checkers can greatly increase the quality of your overall writing.

Correction and sentence improvement features are rightfully considered to be the most important in any grammar checking software. While other tools and metrics should not be looked over, correction capabilities make or break grammar software.

Platform Availability and Integration

The best grammar and spell checker software should be available on as many platforms as possible. Some software exists only in the form of a browser-based service where you paste in the text you want to check. Others work as browser or software plugins that provide corrections while you work.

Browser plugins are incredibly useful, as they provide corrections whenever you’re writing online, be it emails, social media comments, or blog posts. If you’re using apps – like Facebook or Gmail – instead of using their browser-based versions, you’ll use grammar checkers that integrate with those apps directly. Google Docs and Microsoft Word are especially important integrations, as most writers work on either one or both of the platforms. On the other hand, those working in WordPress can rely on the best grammar and punctuation checker options that work in browsers.

Spelling correctly on small smartphones is notoriously tricky, especially when you’re in a hurry. Who hasn’t sent their friends completely unreadable messages because you were typing while walking or working? While our friends are pretty forgiving, your clients, bosses, or colleagues might not appreciate your word salad. Hence, grammar editing software that works on Android and iOS platforms is a godsend.

Translation

While it might not be the main feature people look for in grammar software, translation is still a very handy tool. Instead of heading over to Google Translate, writers can just use the translation capabilities embedded in their grammar checker. Just remember that even the world’s best grammar checker is not as good as a real live translator, but it’s still pretty helpful.

Language Learning

Some of the grammar checkers we’ve reviewed also come with language teaching tools. While the process of grammar and spelling correction is a learning process, some providers offer in-software courses, give tests, and provide feedback based on your previous writing samples.

This helps you improve your knowledge of a language substantially or can serve to overcome common mistakes you’re making. Both Grammarly and Ginger provide reports on your readability and precision, as well as pointing out your most common spelling errors. If you’re already on the lookout for the best grammar checker software, why not take the opportunity to learn a new language while you’re at it?

Note that the vast majority of grammar software only works in English, or at least most of its features are geared towards English. If you’re looking for a Spanish or German correction software tool, for example, there are some options available, but don’t expect the same range of features.

Pricing

The first thing most users look at when checking out any bit of software is the price. Grammar software is no different, and pricing plays an important role in our best online grammar checker comparisons and reviews as well.

Thankfully, a lot of grammar checking programs have a free version available. Some services, like Grammarly, have pretty generous free options, which provide core grammar and spell checking features at no cost. Others may limit you, only allowing corrections when you paste your text into their program and so forth.

However, in most cases, advanced features like rephrasing and restructuring, as well as advanced writing suggestions, are reserved for paid plans. In our reviews, we’ve compared the pricing for each service and what it provides with its paid options.
