Why can't I do a word count in Notes?!
How can I count words in the Mac Notes App?
PS The answer is to add a Quick Action to Automator. There is some guidance on OSXdaily - search for "Make a Word & Character Counting Service for All Apps in Mac OS X".
I have posted this because there was an old question that was asking this, and there wasn't an answer...
The script is as follows:
on run {input, parameters}
tell application "System Events"
set _appname to name of first process whose frontmost is true
end tell
set word_count to count words of (input as string)
set character_count to count characters of (input as string)
tell application _appname
display alert "" & word_count & " words, " & character_count & " characters"
end tell
return input
end run
