Organize your notes into a clear concept map hierarchy
Upload a chapter, lecture deck, or page of notes and get a mind map that ranks ideas from general to specific. Then reorder, expand, and explore it in your browser.
How hierarchy shapes a useful concept map
Most concept maps fail for the same reason: nothing tells the reader which idea matters most. A concept map hierarchy fixes that by placing the broadest concept at the top, then linking narrower ideas beneath it in order of importance. Once the levels are clear, the map becomes a study guide instead of a tangle of arrows.
- Start with the single broadest concept and place it at the top level.
- Keep each child node narrower than its parent so every link reads as a clear relationship.
- Label links with short linking phrases such as causes, is a type of, or requires.
- Limit each level to a handful of nodes so the map stays readable at a glance.
Ranked from broad to specific
Main topics sit at the top level, with supporting ideas and details nested beneath them so the structure matches how your material is organized.
Fully editable
Move branches, rename nodes, or add your own links after generation so the map reflects how your course frames the subject.
Explore at any depth
Collapse or expand each branch to test yourself on the big picture first, then drill into the details one level at a time.
How it works
Add your material
Upload a PDF, DOCX, PPTX, plain text notes, or a photo of a page. Images are read with text recognition.
Review the generated hierarchy
The mind map arranges concepts into levels. Check that the top-level ideas are the broadest and that each child idea fits under its parent.
Edit and study
Adjust any branch, then explore the map in the browser or turn it into flashcards and quizzes from the same material.
Good hierarchy depends on the source material. A chapter on the nervous system, for example, might start with the whole system, then split into central and peripheral branches, then break each into structures and functions. DeckOwl reads your own notes and proposes that ordering, and you can reorder anything that does not match your course.
Use the hierarchy to test yourself. Cover the lower levels and try to recall the branches from memory, then expand one level at a time to check your reasoning. Because the map is editable, you can keep refining it as your understanding improves.

Frequently asked questions
How many levels should a concept map hierarchy have?
Most study maps work well with three to five levels. Fewer levels can hide relationships, while more levels often means the map needs to be split into separate maps by subtopic.
What belongs at the top of a concept map?
Put the broadest concept your material covers at the top, such as a chapter theme or core theory. Narrower ideas, examples, and details then branch downward under the parent they support.
Can I export my mind map?
Exports such as PDF and DOCX are included in the Plus plan at $39/year or $7.99/month. The free plan includes three generations per month and lets you study in the browser.
