Question
What is knowledge graph AI?
Quick Answer
A well-structured personal knowledge graph becomes an input that AI can leverage.
Example: You ask an AI assistant 'What should I study next?' Without your knowledge graph, it gives you a generic learning path. With your graph — 300 linked notes, typed edges showing prerequisites and contradictions, clusters revealing your domains and gaps — the AI can trace your actual understanding, identify the thinnest bridge nodes, and recommend the specific concept that would connect your two strongest clusters. Same AI, same question, radically different answer. The graph didn't make the AI smarter. It gave the AI something structured to reason about.
This concept is part of Knowledge Graphs in the How to Think curriculum.

After completing this path you will have a capture habit that catches thinking before it decays, notes structured so both you and an AI can retrieve them (atomic, identified, context-rich), a personal knowledge graph AI tools can answer from, and the review loop that keeps the system alive. Ask-don't-search becomes your default.
