What Is a Spell-Checker?

A standard English spell-checker is a tool that searches a document or website for misspellings and suggests fixes. It can catch unintentional mistakes that occur when you’re typing or texting quickly, or clear up common confusing word pairs, such as “affect” and “effect.” A free spell-checker provides extra reassurance that the work you’re submitting is polished and free of mistakes that distract from your main points.

Grammarly’s spell-checker helps you write confidently in more than 500,000 apps and websites on your desktop and phone. Ordinary spell-checker apps tell you if a word is misspelled, but Grammarly also lets you know when you’re using a correctly spelled word in the wrong context.

Frequently Asked Questions

How does Grammarly’s spell-checker work?

Grammarly analyzes your writing in real time to detect not only misspellings but also correctly spelled words used in the wrong context.

Where can I use Grammarly’s spell-checker?

Grammarly’s spell-checker works in your browser and across all your favorite websites and desktop apps, such as Google Docs, Microsoft Word, and Outlook. You can even use it on your Android or iPhone by downloading the Grammarly Keyboard.

How is Grammarly’s spell-checker different from my built-in word processor’s spell-check?

Standard English spelling checkers will flag words that don’t appear in the dictionary, but they’re less helpful when it comes to commonly confused homophones. Grammarly’s free spell-check can help ensure you’re not tripped up by “affect” and “effect,” “to” and “too,” and other tricky pairs.
