Why a custom map beats a downloaded template

A free mind map template PDF gives you the shape of a map, but the boxes are empty and the branches were chosen for someone else's course. You still have to sort your own notes into them, which is the part that actually helps you learn.

Example electric circuits mind map branches

Series circuitsSame current flows through each component · Voltages across components add to the source voltage · Total resistance is the sum of the resistances

Parallel circuitsSame voltage across each branch · Branch currents add to the total current · Adding a branch lowers the total resistance

Ohm's lawV = I × R · At fixed resistance, current is proportional to voltage · Doubling resistance halves current at a fixed voltage

Kirchhoff's current lawCurrent entering a junction equals current leaving it · Based on conservation of charge · Used to solve for unknown branch currents

Electrical powerP = V × I · Equivalent forms are P = I²R and P = V²/R · Measured in watts

Built from your material

Upload a PDF, DOCX, PPTX, text file, or a photo of a page. The branches come from your own content, not a stock layout.

Editable and explorable

Rename branches, move ideas, and expand or collapse sections so the map fits how you think about the topic.

Study mode in the browser

The free plan lets you study your mind map in the browser. PDF export is available on the Plus plan.

How it works

Upload your notes

Add a PDF, Word file, slide deck, or plain text notes. You can also photograph a page and it will be read with text recognition.

Generate the map

DeckOwl sorts your material into a central topic, main branches, and sub-points you can open and close.

Edit and study

Adjust the branches, then study in the browser. Export to PDF when you upgrade to Plus.

Generating a map from your own lecture slides or readings keeps the structure tied to what your instructor covered. Branches reflect your terms, your examples, and the order your material introduces them.

Start with the free plan, which includes 3 generations per month and no credit card. If you need a PDF copy for printing or sharing, the Plus plan adds PDF, DOCX, Anki, and CSV export.

Frequently asked questions

How do I organize a mind map for electric circuits?

Put the main concept, such as electric circuits, in the center and make the big ideas its main branches, like Ohm's law, series and parallel circuits, and power. Then add the formulas, definitions, and worked examples as sub-points under each branch.

What should the main branches of an electric circuits mind map cover?

Good branches cover the core laws, circuit types, and quantities such as voltage, current, resistance, and power. Keep each branch focused on one idea so you can test yourself on it later.

Can I export my mind map to PDF?

PDF export is part of the Plus plan, which costs $99.90/year or $9.99/month. The free plan lets you study your mind maps in the browser without exports.

Is it free to try?

Yes. The free plan includes 3 generations per month, and you do not need a credit card to start. Students can get 40% off with a school email.
