I thought it is hard to get the bigger picture of long reads simply by reading linearly because it is like guessing shape of the forest as a whole when you only see the individual trees. I am aiming for an interface where you can switch between granularity levels (forest vs trees) seamlessly.

I am building this idea based on two things: Blinkist and OpenAI's recursive summarization experiment on books. I thought Blinkist summaries are too basic for the books' real depth. And OpenAI's recursive summarization method is really bugging me for chunking the text in fixed sizes which feels too naive.
