Learn how to do a concept map from your own notes

Start with a central idea, add the main branches, then link the details. If you already have lecture notes or a PDF, DeckOwl can draft an editable, explorable mind map from that material so you can refine it instead of starting blank.

Making a concept map that actually helps you study

Knowing how to do a concept map well means choosing a clear central idea and resisting the urge to copy every sentence from your notes. The best maps show relationships between ideas, not just lists of facts.

Put one central idea in the middle and keep it specific.
Limit main branches to about five or seven so the map stays readable.
Use short labels and move longer explanations into sub-points.
Revisit the map after a practice quiz and add anything you got wrong.

Example mind map branches: Newton's laws of motion

First law (inertia)An object stays at rest or keeps constant velocity · Only a net external force changes that motion · Mass determines how strongly an object resists change

Second law (F = ma)Acceleration is proportional to net force · Acceleration is inversely proportional to mass · Force is measured in newtons

Third law (action and reaction)Forces come in equal and opposite pairs · The two forces act on different objects · Rocket thrust is one example

Units of forceNewton (N) equals kg·m/s² · Mass is measured in kilograms · Acceleration is measured in m/s²

Common misconceptionObjects do not need a force to keep moving at constant velocity · A larger force does not always mean a larger mass · Heavier objects do not fall faster in a vacuum

Generate the full set

Editable branches

Rename, move, or add nodes as your understanding changes, so the map stays accurate as you learn.

Explorable structure

Expand and collapse branches to focus on one idea at a time instead of scanning a crowded page.

Built from your material

Upload a PDF, DOCX, PPTX, plain text notes, or a photo of a page and get a starting map based on what you actually studied.

How it works

Start with one central idea

Write the core topic in the middle of the page, such as the main question your course is asking.

Add the main branches

List the five to seven major subtopics that support the central idea and place them around it.

Link and refine

Add short sub-points to each branch and draw connections where ideas depend on each other, then trim anything repetitive.

A useful map usually has a few main branches, each with two to four supporting points. Keep labels short, use single words or brief phrases, and let the links between branches carry the explanation.

Starting from your own material saves time. Generate a draft from your notes, then check each branch against your textbook or lecture and correct anything that is missing or misplaced.

Frequently asked questions

How many branches should a concept map have?

Most concept maps work well with five to seven main branches, each holding two to four sub-points. If a branch grows much larger, split it into two narrower branches.

How do I start a concept map for Newton's laws of motion?

Put Newton's laws of motion in the center, then add one branch for each law. Under each law, write its core statement, the equation or relationship that expresses it, and one everyday example.

Can I make a concept map for free?

Yes. The free plan includes 3 generations per month and lets you study in the browser. Exporting files such as PDF, DOCX, Anki, or CSV requires a Plus plan at $39/year or $7.99/month.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, and students with a school email get 40% off paid plans.
