This post shows the exact steps to create a mind map in NotebookLM, how to use the mind mapping method, and 10 practical use cases you can copy today.

Key Takeaways

• You can create a NotebookLM mind map after you add sources to a notebook.
• A mind map helps you group ideas, find missing sections, and plan next actions.
• You can use mind maps for study notes, content outlines, project plans, and meeting prep.
• You can improve results by using clean sources, clear titles, and focused notebooks.
• ChatGPT can generate a mind map as text (Markdown or Mermaid), but NotebookLM links the map to your sources.
• You can use Coggle for manual mind mapping, then import the structure into your writing plan.

What the NotebookLM mind map feature does

NotebookLM can read the sources you add to a notebook and generate a mind map that groups key ideas into branches. You can use the map as a visual outline. You can also use it as a checklist for what to read next or what to write next.

Why mind maps work well inside NotebookLM

• Source-grounded structure: The map reflects what your documents say, so you start from evidence.
• Fast overview: You can scan the full topic in one view.
• Gap spotting: You can see missing branches, weak areas, and repeated ideas.
• Outline-friendly: You can convert branches into headings for a doc, deck, or script.

What you need before you create a mind map

• A NotebookLM account.
• A notebook with at least a few sources.
• Sources that match one topic (or one project) so the map stays clean.

How to use mindmap feature of NotebookLM (step-by-step)

Use these steps to create your first NotebookLM mind map. The exact button labels can change over time, but the workflow stays the same: create a notebook, add sources, then generate the map.

Step 1: Create a notebook for one clear goal

• Create a new notebook.
• Name it with a clear goal, such as “Q1 marketing plan,” “Biology exam,” or “Client onboarding.”
• Keep one main topic per notebook.

Step 2: Add sources that match the goal

• Add PDFs, Google Docs, copied text, links, or notes (based on what NotebookLM supports in your region).
• Use 5–20 sources for a strong first map.
• Rename sources with clear titles, such as “Policy v3,” “Interview notes,” or “Chapter 6 summary.”

Step 3: Open the mind map tool

• Open your notebook.
• Find the mind map option in the notebook studio tools area.
• Click to generate the mind map.

Step 4: Review the top-level branches first

• Read the main branches and check if they match your goal.
• If the branches feel off-topic, remove unrelated sources and regenerate.
• If the branches feel too broad, split the notebook into two smaller notebooks.

Step 5: Expand branches and label your next actions

• Expand a branch to see subtopics.
• Mark weak branches that need more sources.
• Turn each branch into a task, such as “write section,” “find data,” or “confirm definition.”

Step 6: Convert the map into an outline for writing or study

• Use the top-level branches as H2 sections.
• Use sub-branches as H3 sections.
• Write one paragraph per node before you polish style.

How to use the mind mapping method (simple method you can repeat)

The mind mapping method works in any tool. You start with one main topic, then you add branches for major parts, then you add smaller branches for details. You keep each node short. You use verbs for action nodes and nouns for concept nodes.

Step 1: Write one clear central topic

• Use a short phrase, such as “Launch plan,” “Chapter 4,” or “Hiring process.”
• Avoid vague topics like “Business” or “Health.”

Step 2: Add 5 to 9 main branches

• Use categories that match the job.
• Examples for a launch plan: Audience, Offer, Channels, Budget, Timeline, Risks, Metrics.

Step 3: Add sub-branches that answer one question

• Use “What?” “Why?” “How?” “Who?” “When?” “Where?”
• Example: Channel → Email → Sequence → Subject lines.

Step 4: Keep each node short and specific

• Use 1–5 words per node.
• Use consistent labels, such as all nouns or all verbs under one branch.

Step 5: Use the map to decide next actions

• Circle nodes that need research.
• Star nodes that need writing.
• Cross out nodes that do not support the goal.

Tips to get better mind maps in NotebookLM

Small changes in your inputs can improve the quality of the mind map. Use these tips before you regenerate a map.

Keep the notebook topic narrow

• Use one notebook per project or per class unit.
• Split mixed topics into separate notebooks.

Use clean source titles

Add one summary note per source

• Write 3–5 bullet points for each source.
• Include key terms you want the map to reflect.

Regenerate after you remove noise

Turn branches into actions

• Add verbs to task nodes, such as “Draft,” “Verify,” “Collect,” “Email,” “Measure.”
• Keep action nodes separate from concept nodes.
