Turn your notes into a mind map with clear shape ideas
Upload a lecture PDF, slides, or typed notes and get a mind map that groups shapes by type, with sub-branches you can rearrange and explore.
How to organize shapes in a mind map
Good mind map shape ideas start with the category, not the decoration: a geometry unit might branch into polygons, solids, and circles, each with its own properties. DeckOwl reads your PDF, DOCX, PPTX, or typed notes and proposes that branch structure automatically.
- Group shapes by type: plane figures, solids, and curves.
- Put defining properties on sub-branches, such as the number of sides or faces.
- Link related shapes, like rectangles and squares, to show how one is a special case of the other.
- Keep each branch to four or fewer sub-points so the map stays readable.
Branches from your material
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page and get a mind map built from its main ideas.
Editable and explorable
Rename, move, or add nodes, then expand each branch to see how the ideas connect.
Study tools from the same map
Turn the same material into flashcards with spaced repetition or quizzes with explanations.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file, or photo of a page. No credit card is needed to start.
Review the generated map
Check the branches and edit any shape names or properties that need correcting.
Explore and study
Expand each branch and use the map to recall how the shapes relate to each other.
Once the map exists, you can rearrange branches, add your own sub-points, and expand each node to check how the shapes relate. Then use the quiz output to test whether you can name a shape from its sides or faces.

Frequently asked questions
How do I tell a rhombus from a parallelogram?
Both have two pairs of parallel sides, but a rhombus has four equal sides while a parallelogram does not need equal sides. Every rhombus is a parallelogram, and a square is a rhombus with right angles.
How many shapes should I put on one mind map?
Keep each branch to four to six items so you can recall the whole group at once. Split a large topic such as solids into its own map if it grows past that.
