I can't compliment Grammarly enough! As an English major, I hold proper grammar and usage in high regard. Even as a college senior, however, I am still sometimes confounded by the ever-challenging English language. That's where Grammarly comes in to help me both correct and understand my mistakes. I use both the desktop extension and the mobile keyboard, and I'll never do without again. In fact, I used Grammarly to write this review!
