Turn your GitHub notes into a free mind map
Upload PDFs, DOCX, PPTX, notes, or photos of pages and get an editable, explorable mind map. Start free with no credit card.
Why start from your own material instead of a template
Many people who look for a free mind map tied to GitHub are really trying to learn GitHub itself, and a blank template only helps once you already know the terms. DeckOwl starts from your own notes or course PDFs, so the branches reflect what your class actually covers.
- Map a GitHub lecture or README into main branches and sub-points
- Turn Git commands and workflow steps into quiz questions with explanations
- Study the map in your browser on the free plan
- Export to PDF, DOCX, Anki, or CSV on Plus
Editable maps
Rearrange branches, rename nodes, and add your own points after the AI builds the first draft.
Explorable structure

Works from your files
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page, and the text is read for you.

Frequently asked questions
What GitHub concepts should I learn first?
Start with repositories, commits, branches, and pull requests, since nearly every other GitHub workflow builds on them. Once those feel familiar, move on to issues, forks, and GitHub Actions.
How do I practice Git branching for a GitHub course?
Create a test repository and make a branch, commit a change, open a pull request, and merge it back into main. Repeating the cycle with a deliberate merge conflict builds the skill faster than reading alone.
Can I export my mind map on the free plan?
No. The free plan includes 3 generations per month and studying in the browser, while exports to PDF, DOCX, Anki, and CSV require Plus at $39/year or $7.99/month.
Do I need a credit card to try DeckOwl?
No. You can start on the free plan without a credit card, and students get 40% off paid plans with a school email.
