Is captionz supposed to still work?

[matteo]

• Love the idea, but does not seem to show the captions in the box to the right of the video, iphone, laptop, only captions that show are in the YT video, any chance this is gonna work again? (Or some compatibility to run in some specific browser?)
  I help around at a bilingual non-profit, this would be a very VERY nice tool for a bilingual project that just recently began.

  Neither seems to show the dual captions to the right
  (and nothing in what I suspect is supposed to be a dropdown of second languages available)
  Any help?
  Many thanks!
