This is really impressive! One thing I’ve often wanted is a way to listen to an ebook (say, while cooking), and then later be able to sit down and read from where I left off. This essentially requires the same functionality that Storyteller offers (syncing progress through an ebook and audiobook), though arguably overkill for this use case (since I could handle a more coarse alignment). In any case, is this something Storyteller would be good for? Or are there other tools for the job?
Storyteller works great for this. It even syncs your position across devices. So when I really want to settle in to read, I go ahead and switch from my iPhone where I was listening to my Boox e-ink reader which syncs right to where I left off.
That is actually the exact use case that I originally built Storyteller for! I wanted to listen to my books on long runs, and then switch to reading when I got back.
The Storyteller mobile apps have great support for this, I think. They have fully fledged audiobook players and ebook readers, and you can switch between the two with one tap. And then of course you can also double tap on a sentence and start playing from there, with the app highlighting the currently read sentence.
