I've never tried Grammarly, is it smarter than typical spell check? I always have trouble with certain words that spell check appearantly doesn't understand, typically due to prefixes or suffixes. So words like Reorganization or Disfuntional might get flagged as misspelled even when they are not.
The one that really gets me is the auto correct. I really need to pay attention to what I just wrote because the auto correct just acts on its own. Sometimes it's minor things the changing which version of their, there or they're I'm wanting to one that doesn't fit. But other times it's compl different words, like Pits might get changed to Peaches. Just now the word But was changed to Bit, Word was changed to wort and when I typed in Grammarly it got changed to "Grammar lyrics".
