How the free mind map board works
Mind maps work best when the layout matches how you think, and a free mind map board lets you start that way before paying anything.
- Start from a PDF, DOCX, PPTX, text file, or photo of your notes
- Edit branches and wording after the map is generated
- Expand or collapse sections to study one topic at a time
- Export to PDF, DOCX, Anki, or CSV with a Plus plan
Editable maps
Rearrange branches, rename nodes, and add your own ideas after the AI builds the first draft.
Explore by branch
Expand and collapse sections so you can focus on one topic at a time instead of the whole page.
Built from your material
Upload a PDF, DOCX, PPTX, plain text file, or a photo of a page and the map follows that content.

Frequently asked questions
How do I build a biology mind map I can actually review?
Start with one central topic, then add main branches for the big processes and sub-branches for steps, terms, and exceptions. Keep each node to a short phrase so you can recall it without rereading the full text.
How many branches should a study mind map have?
Most useful maps have 4 to 7 main branches, each with 2 to 4 sub-points. If a branch grows much larger, split it into two topics so each part is easier to review.
Is the free plan really free?
Yes, the free plan includes 3 generations per month and studying in the browser. Exports are paid features on Plus, and no credit card is needed to start.
Can I edit the map after DeckOwl generates it?
Yes, the generated map is editable, so you can rearrange branches and change wording. You can also expand or collapse sections to explore it.
