Make a mind map chart from your own notes
Upload a PDF, DOCX, PPTX, or a photo of a page and get an editable, explorable mind map you can branch, rearrange, and expand.
Why a mind map helps with charts
Charts pack a lot into one picture: axes, units, trends, and the story behind the numbers. Turning them into mind map charts shows how each element connects, from the chart type down to the values it displays.
- Start with the chart type, then the axes and units, then the trend or comparison.
- Keep each branch to a single idea so you can recall it under exam pressure.
- Edit the generated map to match your lecture notes rather than trusting it blindly.
- Turn key branches into flashcards or quiz questions once the map feels familiar.
Reads your files
Works with PDF, DOCX, PPTX, plain text, and images. Photos of pages are read with text recognition.
Editable branches
Rename nodes, add your own sub-points, or drop branches that do not matter for your exam.
Explore one branch at a time
Expand only the part of the map you are studying so the chart stays readable.
How it works
Upload your material
Add a lecture PDF, slide deck, notes file, or a photo of a textbook chart page.
Generate the map
DeckOwl picks out the main topics and nests the details under each one as branches.
Edit and study
Adjust the branches to match your course, then explore the map or switch to flashcards and quizzes.
Upload your slides, a textbook PDF, or a photo of a chart page, and DeckOwl reads the text and builds the branches for you. You can edit any node, add your own sub-points, and explore the map one branch at a time.

Frequently asked questions
Which chart type should I use for comparing categories?
Bar charts work best for comparing values across categories because bar length makes differences easy to see. Use a line chart when you are tracking change over time.
How do I read a chart quickly on an exam?
Check the title, axis labels, and units before looking at the data. Then identify the overall trend or the largest and smallest values and state them in one sentence.
Can I export my mind map to other formats?
Free accounts study in the browser without exports. Plus adds PDF, DOCX, Anki, and CSV export for $99.90 per year or $9.99 per month.
Do I need a credit card to start?
