Word Count in a Rise Course

As Alejandra Seader wrote exporting to PDF is one option. One other would be to export an XLIFF for translation and opening it in a translation tool that handled XLIFF. We use smartcat.com. 

BUT be aware:

1. Some blocks have poetic standard texts that may be hidden in the course but are visible in translations, you need to check this and empty these texts in all states of the block.

2. The labels are not added to the export so you also need to count these words if your labels are not in any of the standard languages. There is a separate export for the label-texts in the label under settings/labels

I agree that a word-count would be useful but even more useful would be a word export similar to that from Storyline.
