Finding the best free grammar checker tool is quite a daunting task. As someone with a huge workload, you cannot possibly manually check things like emails, long blog posts, social media posts, documentation and so forth, and search for grammatical errors in each one at the same time.

And if you’re just starting your business or blog, budget limitations make it almost impossible to hire a professional team for something as trivial as fixing minor grammatical glitches and making your text error-free.

To help you automate ⚙️ your grammar check, we have compiled the top picks for English grammar checkers.

Let’s begin!
