Turn your PDFs and notes into a mind map you can use on a tablet
Upload lecture slides, textbook chapters, or your own notes. DeckOwl builds an editable mind map you can rearrange, expand, and explore one branch at a time.
Why a mind map helps when you study on a tablet
Dense lecture slides on a small screen hide how topics connect. A mind map app for tablet study routine solves that by turning your own material into a branching map you can rearrange and explore.
- Start with one main topic at the center and one branch per heading.
- Keep sub-points short, ideally a phrase or a single fact.
- Collapse finished branches so your attention stays on the gaps.
- Add cross-links between related terms so the map shows relationships, not just lists.
Editable branches
Rename, move, or delete any node so the map matches how your course organizes the material.
Explorable structure
Collapse branches to see the outline, then open one subtopic at a time when the screen is small.
Built from your files
Start from PDFs, DOCX, PPTX, plain text, or photos of pages read with text recognition.
How it works
Upload your material
Add a PDF, Word file, slide deck, or notes. Photos of printed pages work too.
Generate the map
DeckOwl organizes the content into a main topic with branches and sub-points.
Edit and explore
Adjust the layout on your tablet, then turn key branches into flashcards or quizzes.
Mind maps work best when each main branch maps to one heading in your source, with examples and definitions as smaller branches. Editing the map as you review makes the structure stick better than rereading the same pages.

Frequently asked questions
How many main branches should a study mind map have?
Most chapters work well with 4 to 7 main branches, one for each major heading or concept. If a branch needs more than 6 sub-points, split it into two branches.
What is the best way to review a mind map on a tablet?
Start with the outline view, then open one branch at a time and explain it from memory before checking the details. Turn the weakest branches into flashcards for spaced repetition.
Can I export my mind map?
Exports such as PDF and DOCX are part of the paid Plus plan, which is $39/year or $7.99/month. The free plan lets you study in the browser without exports.
Do I need a credit card to start?
No. You can start on the free plan with 3 generations per month without adding a credit card.
