What I like best about OnlineCorrection is simply the fact that it quite literally does exactly and precisely what it sets out to do; correct grammar/spelling online. Additionally, it is fantastic that OnlineCorrection also mentions what type of grammatical error one is making. This feature is particularly beneficial for users in the long run.

Just copy and paste the sentence and it proofreads for us. It highlights the color accordingly, that we can find out the mistakes easily.

I use this tool to double-check my writings, after using other spell/grammar checkers.
