Sometimes the most useful thing is not a summary, a report, or an audio overview. Sometimes you just need to see how the ideas in your notebook connect to each other.

Concept Map turns a notebook’s ideas into a visual network you can scan.

Concept Map in Notebook OS does exactly this. It analyzes your notebook sources and produces a visual network of key concepts, showing how terms, ideas, and topics relate to each other across your material.

When Concept Map Is Most Useful

Concept Map is particularly valuable at two points in a research project:

At the beginning, after you have added your initial sources, run Concept Map to orient yourself. See which concepts appear repeatedly across sources, which are central to the network, and which are peripheral. This helps you understand what your notebook is really about before you start asking specific questions.

At the middle or end, after you have done substantial research, Concept Map helps you see the structure of the knowledge you have built. Are there clusters that suggest distinct sub-topics? Are there isolated concepts that might indicate gaps? Does the map reflect the structure you expected?

Drill into a branch to see how sub-ideas connect under each theme.

What the Map Shows

The Concept Map displays:

  • Nodes — key concepts, terms, and entities from your sources
  • Edges — relationships between concepts, labeled with the type of relationship (supports, contradicts, leads to, is a type of, etc.)
  • Clusters — groups of related concepts that tend to appear together

Central nodes — the ones with the most connections — are typically the core concepts of your research area. Peripheral nodes may be supporting details, edge cases, or areas you have not yet explored deeply.

Using Concept Map for Presentations

Concept Map is a useful starting point when you are preparing to present research. The map structure often reveals a natural narrative — start with the central concept, branch out to related ideas, then explain the connections. This is a better presentation structure than "here are all the things I found."

Concept Map vs. Library Map

These are two different views at two different levels:

  • Library Map — shows how your notebooks relate to each other across your entire library
  • Concept Map — shows how ideas and concepts relate within a single notebook

Use Library Map for organizing your knowledge system. Use Concept Map for understanding and presenting the content of a specific notebook.
