Highlight Graph

Turns your Readwise highlights into an interactive force graph where you can see how ideas connect across everything you've read. It pulls a couple hundred recent highlights, spins up parallel agents to find semantic connections between different sources, then renders a browser-based graph with color-coded books and clickable edges. Same-source highlights get automatic links, cross-source connections are semantic and deliberately sparse. The graph uses screen-relative text scaling and has a sidebar that shows connected ideas when you click a node. Good for when you've been highlighting aggressively and want to see the through-lines without manually tagging or organizing. Built on force-graph with a Python script that outputs standalone HTML.
