Once in a while a “must have” tool comes along that saves time and truly helps in everyday life. I recently came across Grammarly. I have been using this tool and absolutely love it. It helps with spelling, grammar, and even has plagiarism checking (important for grading). Check out their free tool.
I recommend copying and pasting a few previous sermons, school papers, or emails to see how easily they can be improved. I have found the grammatical helps especially useful since it explains “the why” behind their suggestions. It can even help you with active and passive voice. And if you don’t know the difference between these two voices, you will definitely benefit from Grammarly.
