Turn your notes into an editable, explorable mind map
Drop in a PDF, a DOCX, slides, or photos of pages. DeckOwl reads the material and builds a mind map you can rearrange, expand, and quiz yourself from.
Why a mind map maker works for studying
Whimsical-style mind maps are most useful when the branches come from your own course material. A mind map maker that reads your lecture slides, textbook chapter, or handwritten notes lets you skip the blank page and start with a structure you can check against the source.
- Upload PDFs, DOCX, PPTX, plain text, or photos of pages
- Edit nodes and branches after the map is generated
- Collapse and expand branches to review in stages
- Start free with 3 generations per month and no credit card
Built from your own material
Upload PDFs, DOCX or PPTX files, plain notes, or photos of pages, and the map is drawn from what you actually studied.
Editable branches
Rename, move, or delete nodes to fit how you think about the topic. The map stays yours to shape.
Explorable structure
Collapse and expand branches to move from the big picture down to the details you need to memorize.
How it works
Upload your material
Add a file or paste your notes. Text from photos is read with text recognition.
Generate the mind map
DeckOwl organizes the main ideas into branches with supporting sub-points.
Edit and explore
Adjust the layout, then open branches one at a time to review and test recall.
Once the map exists, edit it until it matches how your class frames the topic. Collapse branches to review the big picture, then expand them to drill the details. Because the map is editable, it grows with your notes instead of becoming a one-time sketch.
The free plan includes 3 generations per month and browser study, with no card needed to start. Plus adds unlimited generations and exports for PDF and DOCX, and students get 40% off with a school email.

Frequently asked questions
How many branches should a cell biology mind map have?
Most useful maps have five to seven main branches, each with two to four sub-points. Fewer branches keeps the map readable when you come back to review it.
How do I study from a mind map instead of just looking at it?
Cover the sub-points and recall each branch out loud before checking. Redraw the map from memory a day later to find the branches you missed.
Can I export my mind map?
Exporting is part of the paid Plus plan, which includes PDF and DOCX export. The free plan lets you study in the browser without exports.
Is there a free plan?
Yes. The free plan includes 3 generations per month and browser study, and you do not need a credit card to start.
