I love notebooks as a way to present information, data, code and computations.

However, I cannot stand typing any text into a web browser window. Is there any way to edit a jupyter notebook with a text editor and then run it in the browser? The native json is not really human-editable.

If I am just poking around I use a Jupiter notebook. If I have to do a lot of prototyping, I use the emacs plugin. So the muscle memory typing works.

I find the whole "notebooks are a revelation!" thing kind of amusing, given that we have had REPLs for a long time. emacs is just a big REPL if you know elisp. But, yeah, ein is great.
