Hello,
I don’t think it exists yet, but what would be really nice, would be an app that renders jupyter notebook in the static html form, as it is done on github or gitlab. (e.g. https://github.com/rasbt/algorithms_in_ipython_notebooks/blob/master/ipython_nbs/search/dijkstra-algorithm.ipynb)
A next big step would be an app like google colab (collaborative work on a running jupyter notebook).
But just having a viewer would be really nice to share notebooks to other people who don’t know how to open them normally.
I’ve zero knowledge about app creation, so I’m just dropping the idea !
