No "about" info? No "how it works", "how it was trained", etc.?

It seems to only generate words that match English phonotactics & spelling conventions- things that could be English words. Can it be retargeted to other languages, or to arbitrary word-shape constraints?

I am particularly interested because I've recently undertaken a survey of word-generation software for conlangers (people who create artificial languages, like Quenya or Klingon or Na'vi), and while they do come in widely varying degrees of sophistication, with varying degrees of built-in linguistic knowledge, there are none yet publically available that are based on neural networks.
