Wanting to Be Correct With My Grammar

I am one person who wants to write and be correct with my grammar and sentences. I use a program on my computer called Grammarly.  It helps me. I know I do not have to prove myself to anyone but myself and God, but since my words on computer screens all over the United States and other countries, I need to be correct in my grammar the best I can. Whoever developed Grammarly has my support. Who is with me?
