Before the advent of Windows 10, I often used grammarly for my proofreading needs as well.
While the early versions of Word and OpenOffice used to be sufficient for the task, the writing needs of the students and the level of writing intellect that needed to be provided in the papers began to be hindered by these programs that only did checks on basic forms.
These days though, Windows 10 can do more than just make spelling suggestions, it could even go as far as help you construct full sentences and paragraphs on a higher academic level.
I will agree that nothing beats the human eye when it comes to proofreading.
However, nobody said that a second pair of eyes when reviewing the paper won't be of help.
When a fellow human isn't around to do that, then the software bundled into the Word program is the next best thing. It offers a second opinion on word formation, spelling, and thesaurus suggestions as well.
This cuts the review time for the paper into half because the suggestions are done in real time.
The editing is completed as you write. As far as I'm concerned, this is a benefit of the advanced software development that created Windows 10 and Word 2016.
