I'm not so keep on Grammarly. it seems to be very orientated towards American rather than English. I believe that a Google search is far more of an educational tool, as it provides information about the word in question, and thus expands your knowledge.
You guys are missing the point - a spell checker won't flag a word like "effect" or "insure", when really what you mean is "affect" or "ensure".
Uh oh, Jet Cash, I think you made an oopsie. This entire thread is about you manually reading your posts for spelling mistakes and you have exactly the kind of mistake you are instructing against. Nobody is infallible and it happens to the best of us, very regularly I will type "do" instead of "so" or "got" instead of "get", just because I am thinking and typing quickly without as much thought as might be warranted.
I believe you meant "I'm not so
keen"
