Why build a mind map from your own material

Plenty of people who type mind map generator github want open-source code they can read, fork, and run on their own machine. That is a reasonable goal if you plan to build software, but most students just need a map of their own lecture slides or reading, and writing code for that is a detour.

Upload a PDF, DOCX, PPTX, text notes, or a photo of a page
Edit branches and sub-points after the map is generated
Expand and collapse branches to explore the structure
Turn the same material into flashcards and quizzes

Example GitHub mind map branches

Git commitA snapshot of staged changes · Has a unique hash ID · Includes a message describing the change

Fork vs. cloneFork copies a repo to your GitHub account · Clone downloads a repo to your machine · Forking lets you propose changes without write access

Pull requestProposes merging one branch into another · Shows diffs for review · Allows comments and approvals before merge

.gitignoreLists files Git should not track · Keeps secrets and build output out of commits · Does not affect files already tracked

git fetch vs. git pullfetch downloads remote changes without merging · pull runs fetch then merge · fetch lets you inspect changes first

Generate the full set

Any source material

Upload PDFs, DOCX or PPTX files, plain text notes, or a photo of a page read with text recognition.

Editable branches

Rename, move, or add nodes so the map matches how your course organizes the material.

Explorable structure

Expand and collapse branches to move from the big picture down to the details you need to memorize.

How it works

Upload your material

Add a PDF, slide deck, document, or notes. Photos of pages work too.

Generate the map

The AI pulls out main topics and sub-points and arranges them as a mind map.

Edit and explore

Adjust branches, then study by expanding each one until you can explain it from memory.

DeckOwl skips the setup. Upload a file or a photo of your notes, and the AI produces a mind map you can edit and explore branch by branch. The same material can then become flashcards or quizzes when you are ready to test yourself.

Frequently asked questions

What is the difference between git fetch and git pull?

git fetch downloads remote commits without changing your working files, so you can inspect them first. git pull runs fetch and then merges the result into your current branch.

What should a good GitHub README include?

Start with a one-line description of the project, then cover installation, basic usage, and how to contribute. Keep each section short so a reader can scan it quickly.

Can I use DeckOwl mind maps for free?

The Free plan includes 3 generations per month and studying in the browser, but exports are a paid feature. Plus adds unlimited generations and PDF and DOCX export.

Do I need a credit card to start with DeckOwl?

No. You can start without a credit card, and students get 40% off with a school email.
