Book Mind is a web application that allows users to explore character relationships and storylines in books using AI-powered visualizations.
This leverages Llama 4's impressive 10M and 1M token context windows to process entire books at once, enabling comprehensive analysis of complex narratives and character relationships across lengthy texts.

## Features
