Hi hatmatrix - Currently it's primarily a hosted jupyter service - you can view with no login, or create/run if you login. It does not modify Jupyter itself in any significant way. We hope to add various features in the coming year. In its current form it can be used as a scratchpad, for classes, webinars, conferences, etc. where you have say 100+ ppl that quickly need to follow a tutorial without spending time on installation (it has Anaconda sitting underneath Python).
