More Than a Grammar Checker
Whether you re a native English speaker or just beginning to learn, English grammar can be confusing. But proper grammar isn t the only thing you need to think about. Have you ever sent off an important email only to realize moments later that you forgot to run spell check and missed a mistake in the very first line? Do you struggle with apostrophes or spend way too long trying to identify the correct place to use a comma? Even if you re confident in your grasp of English grammatical rules, it s easy to mistype when you re writing fast and concentrating on your ideas.

Grammarly is more than a grammar check, more than a spell check, and more than a punctuation corrector. It s a comprehensive writing tool that helps you write clear, flawless text that will impress your readers. With Grammarly, you ll build writing skills while you re correcting grammar, spelling, and punctuation mistakes as well as sentence structure problems, misused words, typos, and more.
Why Use Grammarly s Writing Tool?
Good writing is for everyone. Whether you re working on an essay, a blog post, or an important email, presenting your ideas with clear, correct language makes a big impression on your reader. When the stakes are high, a grammar corrector can be a lifesaver. But with all the grammar checking tools available, it s critical to pick one that you can rely on to catch mistakes every time.

Grammarly s products run on a sophisticated AI system built to analyze English sentences. Unlike other tools (most spell checkers, for instance) that rely on a rigid set of rules, Grammarly takes context into account when making corrections or suggestions. This means that when you write “affect” but you meant “effect,” Grammarly will let you know that you spelled the word right but used it in the wrong context.

Try the online editor for checking longer papers and essays, the iOS or Android app for mobile writing, and the browser extension to make sure your writing is clear and mistake-free on any website.

When you create a Grammarly account, you ll be able to select your preferred English dialect, add words to your personal dictionary, and check your text from anywhere. Plus, you ll receive weekly updates about your vocabulary, productivity, and top mistakes, so you can track your improvement over time. Online Grammar Check for Everything You Write
