Why a custom mind map beats a generic worksheet

Most printable templates use someone else's topics, so their branches rarely match what your instructor covered. A mind map worksheet PDF built from your own lecture slides or notes fixes that: DeckOwl reads the text, pulls out the main ideas, and arranges them as a map you can edit and explore.

  • Branches follow your own lecture order, not a generic template.
  • Edit any node to add definitions, examples, or corrections from class.
  • Study in the browser on the free plan, with 3 generations per month.
  • Export to PDF on the Plus plan when you want a printable worksheet.

Built from your material

Upload a PDF, DOCX, PPTX, text file, or photo of a page, and the map is drawn from what your course actually covered.

Editable branches

Rename, move, or add sub-points to any branch so the map matches your instructor's terms and your own understanding.

Explorable map

Expand and collapse sections as you study, so you can focus on one branch at a time instead of scanning a full page.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file, or photo of a page. No credit card is needed to start.

Generate the map

DeckOwl pulls out the main ideas and arranges them as a branching mind map with sub-points under each branch.

Edit and study

Adjust the branches, study in the browser, and export to PDF when you need a printable copy on the Plus plan.

Because the map stays editable, you can rearrange branches, add your own sub-points, and collapse sections as you study. PDF export is included in the Plus plan at $99.90/year or $9.99/month, and the free plan lets you build and study maps in the browser with 3 generations per month.

Frequently asked questions

How many branches should a mind map have for one lecture?

Most lecture mind maps work well with 4 to 7 main branches, each holding 2 to 4 sub-points. Fewer branches usually means the topic is too broad to review in one sitting.

How do I turn a mind map into a study routine?

Cover the sub-points and recall them from each main branch before checking the map. Redraw the map from memory once a day, then compare the two versions to find gaps.

Can I export the mind map as a PDF?

PDF export is included in the Plus plan, which costs $99.90/year or $9.99/month. The free plan lets you study maps in the browser with 3 generations per month.

Does it work with photos of printed pages?

Photos of pages are read with text recognition, so clear, well-lit photos of printed text work best. Check the generated map against the original page before you rely on it.
