This free extension ensures that your writing is error-free via the grammar and style checker LanguageTool. LanguageTool detects many errors that a simple spell checker cannot, such as grammar issues, commonly confused words, and punctuation oversights. Additionally, LanguageTool offers style suggestions to elevate your writing: synonym replacements for overused words, concise rephrasing of wordy sentences, and formal alternatives to commonly used expressions.

LanguageTool is designed with simplicity in mind, instantly analyzing your text as you type. It is compatible with most platforms, including social networks such as Twitter and LinkedIn, and e-mail services such as Gmail.

With LanguageTool, our aim is to give users a full-feature grammar checker and proofreader that will enable them to have control and confidence over their content. While LanguageTool is a vital extension for non-native speakers, it also recognizes many mistakes that are frequently made by native speakers. This grammar and spelling correction works across several varieties of commonly spoken languages, and is capable of distinguishing between American and British English. LanguageTool also features a personal dictionary for exceptions or words that you might commonly use, but are not found in a conventional dictionary; it will learn to recognize these words for future grammar checking and proofreading.

Unlike other services like Grammarly (a.k.a. Grammerly :-), ProWritingAid, and Quillbot, LanguageTool supports more than 25 languages including English, Spanish, French, German, Polish, and Russian (see below for the complete list).

Risk impact

Grammar & Spell Checker—LanguageTool requires some risky permissions and may not be safe to use. Exercise caution when installing this add-on. Review carefully before installing.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Grammar & Spell Checker—LanguageTool is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.

Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on, especially ones with higher risk impact and/or higher risk likelihood.

Very easy to use. And yes, indeed. Mate, any comment I write? Sound very professional. Great program. I recommend it for everybody.

After weeks of exasperation because Grammarly would not work on either Edge or Chrome when I was entering text on my continuing education website -- with personally embarrassing spelling errors which I am sure hurt my Google ranking -- I finally loaded LT onto Edge and my blood pressure has dropped at least 30 points (woot!). It works. Thanks, LT

This is the best grammar checker, that's all there is to it.

The manifest file declares the requirements and permissions that an Edge add-on will have access to. By reviewing the manifest, you may be able to determine if an Edge add-on is over-reaching (for example, if an extension is overriding your new tab page, or search provider, or requesting access to your web activities without any good reason).
