not sure what the livebook is--the landing page is not sufficiently clear or coherent.
The difference between features and benefits. It's good at telling you the features (what it does) but not so much the benefits (why you would use it, how it can help you).
A common issue, but more understandable in this case than most as your average visitor to the Livebook site will likely know they have a need for it already, rather than end up there based on a 'random' link (like this thread).
That's pretty clear and coherent to me.
Think Jupyter Notebooks (if you're familiar with the python world), but collaborative and for Elixir.
For example, recently an addition to add automatically generated sequence diagrams to Livebook Kino (https://github.com/livebook-dev/kino/pull/165). So generate code which shows a supervision tree, and automatically create a visual diagram of the code in one place. Pretty great for learning and explanatory material.
