We currently have a notebooks UI (e.g., https://sourcegraph.com/notebooks/Tm90ZWJvb2s6MTg1NA==), but the plan is to roll Cody into this and make it a super rich UI for learning/understanding anything and everything about code
Sounds promising, but that looks to me like a different kind of notebook? It seems to be a way to write documentation with some fancy features.
An Observable notebook is a standalone program, sort of a cross between a makefile and a spreadsheet. You write code snippets in JavaScript to calculate things and it automatically recalculates them when dependencies change. It's pretty powerful since you can import JavaScript libraries (to draw graphs, for example) and call API's.
