Do you know what are the scaling limits of this kind of graph?
EDIT: In the past people used to pore over each line of series like asoiaf to hand compile their own wiki of this kind of data and GRRM was known to consult them to ensure consistency in his universe. So you never know, a tool like this may finally help him get over the finishing line for resolving his nebulous knot of plot lines! (tongue in cheek...)
On scaling: context almost completely stops growing after chapter ~70 in the case of the Oz series. By my estimates it's chapter ~90 at the latest depending on the story — for practically any story, context growth flattens out around there. The theoretical limit of the system should be somewhere around 80 million words.
1. A wiki for the story. For the author and for readers, so you don't forget what happened 300 chapters ago, which promises are still active, and so you can explore a story you love structurally.
2. Translation. The system scales to millions of words, so when it translates chapter 100 it has the full, precise context of what happened in chapter 1, including speech registers, relationships between entities, and a synopsis of the world.
I read very long web serials myself, and I kept losing the thread of stories I loved. So primarily it's a way to build a model of a story's world, and two things fall out of that.
