Whether you’re sending out cold emails all day or drafting up campaigns and proposals, it’s tedious to spend time pouring over grammar. You can waste precious time deciding if you’re supposed to be using ‘affect’ or ‘effect’ or if you’ve used the word ‘very’ too many times. Instead, finding the best grammar checker for your work can automate this task and boost your productivity.

These days, there are many grammar checkers out there that all claim to be the best. Here are some of the best grammar checkers used and trusted by thousands of users every day.

Some grammar checkers may automatically edit content as you write, while others will flag incorrect spellings or awkward phrases for you to review. Many editors will even take you line by line to identify passive sentences, overly long paragraphs, or other complex errors that even keen human eyes may miss.

Using a grammar checker can give you some peace of mind when you’re writing a lot of content daily. Never again will you accidentally and embarrassingly leave off the ‘o’ at the end of ‘hello’ or misspell a simple word on a huge event poster. This software can help automate editing, so you can focus on getting your thoughts written down and submitted by the deadline.

What are the best functions of a grammar checker?

Some grammar checkers may just check the basics, like spelling and punctuation. More advanced programs can identify passive sentence structures, awkward phrases, and copy that is too complex for the average reader. How you work will greatly determine what functions you need.

Consider looking for options that check spelling, grammar, readability, redundancies, sentence length, and repeated words. For example, some grammar checkers can even tell if you have started consecutive sentences with the same word, so you can avoid your copy sounding monotonous.

If you’re wanting to create error-free copy, consider one of these top grammar checkers, both free and premium. You’ll find options that even work for emails, social media, and on your phone.

1. Hemingway Editor

Looking for a free grammar checker? Consider Hemingway Editor, which is one of the best free grammar checkers with plenty of advanced features. This website and desktop app reviews your writing to determine readability with the Flesch-Kincaid reading level, which generally recommends that you aim for easy, conversational language to fairly easy-to-read content (grades 6 through 8 on the scale).

This program will scan content for adverbs, passive sentences, and complex or long sentences. It highlights issues in various colors, so you can edit in real-time. The big drawback with this free program is that you’ll need to copy and paste your text over into the editor; it doesn’t scan your text in emails or other documents.

2. Grammarly
