Could you elaborate a bit on what you offer that out-of-the-box Jupyter does not?

From my admittedly limited experience with Jupyter, it is already an interactive coding and visualization tool which can be exported to HTML.

Can you not include Plotly plots in vanilla Jupyter?

The kyso homepage says that you beautifully render the notebooks? Given that they're already html, does that mean custom style sheets? Something more?

Or is the main value add just a wrapper over git to make versioning and sharing easier?

Thanks.
