How mind map sharing works for students

A shared mind map is only useful if the people receiving it can follow the branches, so DeckOwl starts with your own material. Upload your lecture slides, reading PDF, or typed notes, and the AI turns them into a mind map sharing draft you can edit before anyone else sees it.

  • Start from your own notes or slides rather than a generic topic map.
  • Edit branches before sharing so the structure matches your course.
  • Export PDF or DOCX copies on Plus to send to classmates.
  • Use the same map to build flashcards or quizzes from the same material.
Example biology mind map branches for cell structure
Cell membranePhospholipid bilayer · Selectively permeable · Embedded proteins
MitochondriaSite of cellular respiration · Produces ATP · Has its own DNA
NucleusHolds genetic material · Enclosed by nuclear envelope · Nucleolus makes ribosomal RNA
Endoplasmic reticulumRough ER has ribosomes · Smooth ER makes lipids · Smooth ER detoxifies drugs in liver cells
PhotosynthesisLight reactions in thylakoids · Calvin cycle in stroma · Produces glucose and oxygen
Generate the full set

Built from your own material

Upload a PDF, DOCX, PPTX, plain text notes, or a photo of a page, and the AI reads the text and organizes it into branches.

Editable and explorable

Rename branches, move ideas around, and expand or collapse sections so the map matches how your class organizes the topic.

Export on Plus

Free accounts study in the browser. Plus adds PDF and DOCX exports so you can send a copy to classmates or a study group.

Frequently asked questions

How should I organize a mind map for a biology exam?

Group ideas by structure first, then function, then examples, so each main branch answers one question. Keep sub-points short, around two to four per branch, so you can recall them without reading a paragraph.

What makes a mind map easier to study from than a list of notes?

A mind map shows how concepts connect, which helps you remember relationships between terms. Testing yourself by covering branches and recalling the sub-points is a good way to use it.

Can I share a DeckOwl mind map with classmates?

Yes, on the Plus plan you can export PDF or DOCX files to send to others. The free plan lets you study the map in your browser without exports.

Is there a free plan?

Yes, the free plan includes three generations per month and browser study. Exports are available on paid plans, and no credit card is needed to start.
