Which is the Best Online Grammar Checker?

If you’re writing for an audience, using a good online grammar checker is an indispensable skill. Grammarly, AutoCrit, PaperRater, Hemingway, and PaperQueen are some of the top tools. Which one is right for your needs? This article compares and contrasts their features. Hopefully, you’ll be able to choose the one that suits your writing style best.


Grammarly is an online tool for proofreading your writing. This tool is free and offers free Google extensions. To begin using the tool, sign in to your account and click the “New” button. Type your content in directly or copy and paste it from another document. Alternatively, you can upload your content for proofreading. You can even upload your own document, so that Grammarly can check it for you. Once you’re done, you can save the document and continue proofreading it later.

There are several ways to use Grammarly, but the most convenient is to install its extension in your browser. You can install Grammarly on Google Chrome and Mozilla Firefox. After downloading the extension, sign up using your email address. The tool will analyze your writing and recommend corrections within seconds. You can also upload a document to Grammarly and have it checked in real time. The web tool is free to use, but you can only access its premium features if you’re a paid member.


The AutoCrit online grammar checker can highlight nonexistent words and characters. It can also highlight invented languages, locations, and cities. Its free plan does not include genre-based guidance, but it does offer instant feedback on your draft. Its premium version allows you to add as many as ten grammar rules. Despite its free plan limitations, AutoCrit is well worth a try. We’ll look at how to get the most out of AutoCrit in this review.

The free plan comes with a limited number of features, such as an online dictionary. There’s no mobile app, and many features are reserved for the premium version. The desktop version only supports internet connections. Premium users also receive lifetime updates. The premium plan offers the same benefits as the free version, but with a little extra. Those with a tight budget should opt for the Professional plan. It costs $30 a month and includes two free months.


While you might be tempted to use the free grammar-checking apps on the market, they are hardly worth the money. A free grammar checker is not nearly as powerful as Hemingway, and its main focus is to identify and fix fundamental writing problems, such as passive voice and overused adverbs. Still, the free Hemingway editor can help you improve your text, and it will highlight suggested improvements as you write.

Hemingway is easy to use, and it has a simple, uncluttered interface. The homepage contains an editor that evaluates your writing and grades it for readability. Toggling between distraction-free and non-distracting modes makes it easy to focus on the most important parts of your writing. Once you’ve entered your text, you’ll see whether Hemingway has highlighted any errors, and how many they are.


The most important feature of PaperRater is its low word count limit, so it is limited to checking around 1,500 words per month. In addition, its free account does not include a chat or phone support option. If you are looking for human proofreading, you may want to consider purchasing a premium plan. This subscription comes with additional features like no ads and enhanced audits. However, it has one major flaw: it does not support non-English texts. Occasionally, PaperRater flags a sentence as non-English, and it does not deal well with various grammar styles.

Unlike most free tools, PaperRater also provides automatic essay scoring, readability statistics, and plagiarism detection. PaperRater uses Google and Bing search indexes to compare your text to the ten billion documents in their databases. It is free to use, and requires no login or sign-in. It also provides automatic proofreading suggestions for essays and other types of papers. The paper you submit is reviewed by a human, so you will never be left wondering if you misspell something!


The NOUNPLUS online grammar checker is an excellent tool for improving your writing skills. With a massive database, extensive dictionary, and facility for using synonyms, this tool will provide you with a wealth of grammar tips. The free service offers a great way to improve your English.
