Why start from your own notes instead of a generic template

A blank page is the hardest part of brainstorming, so a starting structure helps. Instead of a generic printable, DeckOwl builds a brainstorming mind map template from the material you already have, so the branches reflect your subject rather than someone else's.

Sort ideas into branches before you write a first draft.
Collapse branches to focus on one theme at a time.
Add sub-branches when a single idea needs more detail.
Start on the free plan with 3 generations per month.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes, or a photo of a page.

Generate the map

DeckOwl reads the content and organizes it around a central topic with main branches.

Edit and explore

Reshape the branches and keep refining the map as your brainstorming continues.

Upload lecture slides, a reading, or your own rough notes, and the map pulls out the central idea and its main branches. You can then rename, move, or add nodes as your thinking changes, which keeps the structure editable instead of fixed.

Frequently asked questions

What should a brainstorming mind map include?

A central question or topic, several main branches for distinct themes, and short sub-branches for individual ideas. Keep labels to a word or two so the structure stays easy to scan.

How many main branches should I start with when brainstorming?

Most people find four to seven main branches manageable. Add more after you have grouped similar ideas, since too many branches early on can slow down idea generation.

Can I export my mind map?

Export is a paid feature: Plus includes PDF and DOCX export along with Anki and CSV. The free plan lets you explore and study in the browser.

Yes. The free plan includes 3 generations per month and no credit card is needed to start. Students get 40% off with a school email.
