Hi @iangreig, welcome to the Supernotes community!
At the moment we don’t have a word count functionality – only a character count (counting down from 1200 characters - the size of 1 card).
I see for your use case how an ascending character and word count would be very beneficial. I have opened a feature request, and since this is quite an easy addition we will look into adding this in the next update!
@iangreig As a workaround, are you able to filter out the cards you need? If so, you can export them to markdown and open the file in Typora for example. You can see the word count there.
