While pristine English is not a necessity in everyday life, making sure your grammar is correct in documents, communications, and submissions go a long way towards giving your work a professional feel.


Luckily, we no longer have to rely solely on tools like Microsoft Word’s spelling checker. From browser extensions to web applications, there are a variety of options to choose from based on your needs and budget.

Here are the best grammar checkers to choose from.

1. Grammarly: Best Grammar Correction Tool for Everyday Use

The mobile version of the app is a useful perk that few other grammar checkers include for free. This flexibility and Grammarly’s overall quality as a grammar checker make it perfect for everyday use.

The main criticism of Grammarly is that it is occasionally overzealous in its identification of errors. Furthermore, its free version often prompts you to upgrade to a paid version to correct some errors.

2. Scribens: Best Free Grammar Checker for Students

Academics raise red flags about free grammar correction apps and plagiarism checkers over concerns about the ownership of their intellectual property. But not every student has access to paid software that guarantees their papers are not stored.

However, Scribens is a free grammar checker that does not transfer any submitted text to their servers. This means you can feel secure in your privacy, but also in your ownership over your intellectual property.


You can not only submit your text for checking via the web tool, but you can also download browser extensions.

Scribens checks your grammar and style, identifies repeated words, and sorts your errors with color coding. The downside is that the web checker converts all your text to plain text, meaning you will have to redo any formatting after correcting your errors.

3. ProWritingAid: Best Grammar Checker for Writers and Professionals

ProWritingAid is a great choice for writers and professionals since it does more than check your grammar for structure. In fact, the app also checks your writing for redundancies, repetition, cliches, and other writing errors.

The tool also provides suggestions for improving your writing in terms of flow and ease of reading. ProWritingAid also has the ultimate goal of improving your writing overall, rather than simply correcting the errors you’ve already made.

You can either use the company’s web editor or its various software integrations. ProWritingAid includes extensions for Firefox, Chrome, Google Docs, and a few other platforms.

The major downside is that there is no free version of ProWritingAid—a subscription is required to use the software. However, a two-week free trial is available for users who want to try it out first. After that, a yearly subscription purchase is required.

4. Ginger: Best Free Grammar and Punctuation Checker

Many of the grammar checkers on this list offer free or trial versions. But you’ll often find that a significant number of features are locked out of these versions.

However, Ginger offers a robust free version through its browser extensions. The benefit of Ginger’s free version over other grammar checkers is its number of features as well as its lack of prompts to upgrade.

The free browser extension includes an easy-to-use editing window with translation, dictionary, and thesaurus tools.

When Ginger’s grammar checker flags grammar errors in your writing, it doesn’t use the flag for a forceful subscription. For example, Grammarly’s extension flags stylistic errors, but you can choose to subscribe and explore these apparent errors in detail.

In terms of accuracy, Ginger’s extension doesn’t over-identify errors or insist on comma placements that are inaccurate or jarring.

Its open-source nature means that the tool is very simple and doesn’t come with the same features as paid grammar checkers. However, it is still a useful tool that is proficient at identifying errors.

After The Deadline identifies spelling errors, grammar errors, and stylistic errors. It is also able to preserve most of the formatting of the text that you submit for checking.

The site provides a few extensions. However, these are available on GitHub rather than the usual browser store pages. The easiest way to use After The Deadline is with its web app.

    I use Grammarly on my Chromebook, but it will not work in Evernote, which I use for a lot of writing. I also would like to read if there is any conflict with using more than one of these spell checkers.

      I just realized after I posted the comment that I actually have Ginger installed on my Chromebook, not Grammarly.

    Grammarly is good if someone wants to use iy everywhere on every website. But if you wanna just check on a particular site and have privacy then is the best one in my opinion.

      Obviously it doesn't also check spelling.

    Too bad that grammar checkers are not routinely used by journalist and reporters for the written media. It seems they mostly rely on spellcheckers. Over the past ten years the number of grammar errors has risen significantly. Homophones are the biggest problem.
