See How Your Knowledge Connects: The Knowledge Graph

See your knowledge as an interactive visual map. Discover hidden connections and knowledge gaps in your learning.

1 min read

Your brain connects ideas. Your notes don't. Until now.

What Is the Knowledge Graph?

A visual map of everything you've learned and how it connects. Open the Playground from the sidebar to see it.

Nodes = Your videos, concepts, and interests

Edges = Connections between them (shared topics, concepts, themes)

What You'll Discover

Hidden Connections

You watched a video about "habit formation" and another about "compound interest." The Knowledge Graph shows: both discuss exponential growth from small consistent actions.

You didn't notice. The graph did.

Knowledge Gaps

Your graph is dense around "machine learning" but sparse around "data engineering." This reveals: you understand the models but not the infrastructure.

Action: Save some data engineering videos to fill the gap.

Learning Clusters

Topics naturally cluster:

  • Cluster 1: Productivity + Habits + Psychology
  • Cluster 2: Programming + AI + Math
  • Cluster 3: Finance + Business + Marketing

These clusters represent your mental models.

How to Use It

Exploration Mode

  1. Open the Playground
  2. Click any node (video or concept)
  3. See all connections
  4. Click connected nodes to explore
  5. Discover relationships you didn't plan

Before Starting a New Topic

  1. Open the graph
  2. Search for the new topic
  3. See if it connects to things you already know
  4. Start learning from familiar connections outward

Weekly Review

  1. Open the graph
  2. Check: "What grew this week?"
  3. Notice: "What unexpected connections appeared?"
  4. Plan: "Where should I explore next?"

Pro Tips

  • Zoom out to see the big picture of your knowledge
  • Zoom in on a cluster to see detailed connections
  • Click edges to understand WHY two things are connected
  • Confirmed connections are displayed with solid lines
  • AI-suggested connections use dashed lines—confirm or dismiss them
