Gramarly

It is really really good but the other than the starter it costs money. I like it a lot and I recommenced it for you

This program has help my to make better my gramar when writing to friends or teachers I recomend this program a lot!

This program checks errors in writing, and it has flaged punctuation as incorrect when other sources clearer state as correct. The sources I am referring as showing correctly are, "A Pocket Style Manual" by Diana Hacker; The Chicago Manual of Style in writing"; "The Elements of Style" by William Strunk Jr. As of this date, I am still waiting to receive feedback on my questions and remarks.
