Maybe for you, I am dyslexic and my writing sucks. Even in my mother tongue, let alone English. If I need to give a good impression, I rely heavily on Grammarly because it can reformulate sentences in a way I never could.

Starting with Windows 10 Microsoft has been keylogging for the same reason and saving the data for themselves to use for whatever they want. I'd consider that a 3rd party personally.
