Generate the full set

Built from your material

Paste notes or upload a PDF, DOCX, PPTX, or a photo of a page. The map is drawn from your own content, not a generic template.

Editable branches

Rename, move, or delete nodes as your understanding changes. The map stays yours to reshape while you study.

Explorable structure

Expand and collapse branches to focus on one topic at a time, then switch to flashcards or a quiz on the same material.

How it works

Add your notes

Upload a file or paste text. Photos of pages are read with text recognition.

Generate the map

DeckOwl organizes the content into a central topic with main branches and sub-points.

Edit and study

Adjust the layout in your browser, then review the branches until you can rebuild them from memory.

A mind map helps most when you rebuild it from memory after a session. Start with the central topic, check which main branches your source covers, and add sub-points only where the material supports them. Then hide the branches and test yourself.

The free plan includes 3 generations per month and browser study. Exporting maps and files is a paid feature, available on Plus at $39/year or $7.99/month.

Frequently asked questions

How many branches should a mind map have for a cell biology unit?

Most unit-level maps work well with 5 to 8 main branches, such as membrane, nucleus, organelles, and transport. Each branch should hold 2 to 4 sub-points you can explain without looking.

How do I use a mind map to study for a biology exam?

Build the map from your notes, then cover the sub-points and try to recall each one aloud. Redraw the map from a blank page and compare it to the original to find gaps.

Can I download DeckOwl as desktop software?

DeckOwl runs in your browser rather than as an installed desktop app. The free plan lets you create and study maps there.

Can I export my mind map for free?

No. Exports are paid features: Plus includes PDF, DOCX, Anki, and CSV export for $39/year or $7.99/month, and Pro adds QTI 2.1 and Moodle XML export.
