Starts from your own material

Upload PDF, DOCX, PPTX, plain text, or photos of pages. Text recognition reads the pages so the map reflects your course, not a generic template.

Fully editable

Rename branches, move sub-points, and add details yourself. The AI gives you a starting structure, and you decide what stays.

Explorable layout

Expand and collapse branches to focus on one section at a time, then return to the full picture when you want to see how ideas connect.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file, or a photo of your page. No credit card is needed to start.

Review the draft map

DeckOwl builds a mind map with the central topic and main branches. Read through it to check the structure against your material.

Edit and explore

Reorganize branches, add missing details, and expand sections as you study. Switch to flashcards or quizzes when you want to test recall.

A map works best for topics with clear categories and relationships, such as the branches of US government. Build the top level first, then add the powers and checks under each branch so you can see how they connect instead of memorizing a list.

Frequently asked questions

How many main branches should a mind map for US government have?

Most introductory civics maps use three main branches: legislative, executive, and judicial. Under each one, add sub-branches for the body, its key powers, and how it checks the other two.

How do I study US government branches with a mind map?

Start with the three branches in the center, then add what each one does and how it limits the others. Redraw the map from memory and compare it to your notes to find gaps.

Can I edit the mind map after it is generated?

Yes, you can rename, move, and add branches to the draft. Exporting your work to PDF or DOCX is part of the Plus plan, while the free plan lets you study in the browser.
