Fitting that I get a Grammarly ad in the lower margin.
I've heard of Grammarly through it's hilarious Youtube ad that consists of a social media manager who essentially uses Grammarly as a crutch because she's laughably bad at grammar. I once had to write a couple essays for school, and I downloaded it so I could get a small boost. One minute into having it, I find out that it's not compatible with Google Docs and promptly uninstall it.
It's not a bad tool to use (I assume), but you're better off understanding proper grammar rather than writhing your hand all over a keyboard and fixing what it says to fix.
