How it works

From books to breakthroughs

1

Deep Processing

Every book is read chapter-by-chapter. Concepts, frameworks, and relationships are extracted with precision — not auto-generated summaries, but genuine analytical depth.

2

Graph Construction

Ideas are connected through 17 typed relationships — supports, contradicts, extends, applies — revealing how concepts relate across books no single author could see.

Why this exists

What makes this different

Book summary services give you bullet points. Margin Notes builds a living knowledge graph that reveals how ideas connect, contradict, and compound across books.

Cross-Book Connections

Social Proof appears in Cialdini, Berger, and Voss — each through a different lens. 17 typed edges reveal exactly how each author treats the same idea.

Premium Analysis

938 individually written analytical posts. Not generated templates — deep-dive content exploring implications, limitations, and cross-book patterns.

Interactive Graph

WebGL-powered knowledge graph with semantic zoom, re-centering, edge colors by type, and Cmd+K search. Click any node to read its full analysis.
