If you’re a non-native speaker, getting worried about your writing skills and complaints from your readers would be a common situation. Also, due to a limited vocabulary, it’d be difficult to churn out high-quality articles that bit the bullet and get popular.
I have faced the same situation and wanted to improve myself. Grammarly has helped me a lot in this regard. It’s a great grammar checker tool and worth every money spent.
Check out my Grammarly Review for detail description of how Grammarly has helped me, what are the pros and cons, and is it better than a human proofreader?
