Ready to pony up the big bucks for a badass grammar checker? Hold your horses. You must weigh your options carefully. Here are some of the things to look out for when choosing a grammar checker.

Best Grammar Checker Apps FAQs

How do you check if a sentence is correct or wrong?

It depends on the grammar checker tool. Some programs like Hemingway Editor highlight an incorrect sentence. Grammarly parses out the entire text and shows you where your mistakes lie and how to correct them, even re-writing the sentence to make it more readable.

How can I check my grammar mistakes?

Using one of the best grammar checker apps from our list, you can check grammar mistakes in an email, Word documents, and using a browser plugin, on forms you fill out online. Using one of these tools, you can upload a document or copy/paste in your raw text. The grammar checker will go through your document line-by-line and identify all the mistakes and issues. Some of these offerings check all your text on the fly as you type.

Which grammar checker is the best?

Especially for writers, the best grammar check app is a personal choice. However, popularity-wise, ProWritingAid has a strong user base and great reviews. It’s continually evolving through updates adding new features, and it checks all the boxes for anyone who writes professionally.

Is Grammar Checker safe to use?

Before you purchase a grammar checker, be sure to read their privacy policy and check into their security protocols. Most of them, like ProWritingAid, and Grammarly vow to keep your information safe and private.

How can I correct my grammar?

Depending on which tool you use, the process may be different. However, with most of them, you will see an alert and highlighted or underlined text that needs correction. The grammar checker may suggest a fix that you can then accept or reject or change it yourself.

Is Grammarly better than Word?

Absolutely! Grammarly is much better than Word, although it is not perfect. Many writers use Grammarly to fix their commas and other more serious grammatical and spelling issues and then open the same document in Word to do a final check. Sometimes Word will find a couple of issues that even Grammarly missed. It’s best to use more than one to cover all your bases when writing professionally.

Is there any good free English grammar checker?

Yes. Grammarly has a free version you can use online. You can simply copy and paste in your text, and the program will examine it for you and present a list of corrections for you to review. Other programs also have free versions, but not many are as accurate as Grammarly.

What is the best grammar checker software for writers?

There is no one perfect grammar checker for writers. Good writers that strive to produce perfect content consistently use a combination of grammar checkers to be sure they catch every single error, missed comma, typo, and misspelled word.

Is there any website to check grammar?

Yes. Many of these programs are online grammar checkers. Most of them have websites where you can type text directly into a box and review it; you don’t have to download any software or install any apps.

Is a grammar checker accurate?

Again, that depends on the grammar checker you use. Some are more accurate than others. Typically, those that use extensive databases and AI learning are the most reliable.

Conclusion

If you’re looking for the best-in-class grammar checker, then you have to go with Grammarly . It’s a cut above the rest. However, Ginger, ProWritingAid, and WhiteSmoke are excellent alternatives, especially If you don’t want to pay the hefty fees charged by Grammarly.
