Have global spell check and word count, with Enso Words
Enso Words allows you to spell-check in all of your programs.
It can also give you the definitions or synonyms of a word that you see in any application.
Other features: use the “word count” or “character count” commands to get this information. Character count will count the number of characters in a selection. Word count will count the number of words in a selection.
In my opinion the program is not convenient. You need to press a button (capslock) then type a command while you keep pressing the button (the command is “spellcheck”) in order to load your text to the application for spellcheck. Even there, you don’t see probable corrections, but only when you right click each marked word. However, since the program is free you have nothing to lose to try if it can help you.
