Makes sense but I think the main issue with the workflow is that the user is having to type words out? As a vocab builder it would be nice to do more suggestive words or something that does not force me to type in words.

As I mentioned in another comment though, the ideal workflow would be an integrated ebook reader that lets you tap words without context switching.
