Turn your notes into a mind map template with lines
Skip the blank page. Upload your lecture notes or a PDF and DeckOwl builds an editable mind map with connected branches you can reshape and explore.
Why a custom mind map beats a blank lined template
A printable mind map template with lines gives you the shape, but you still have to fill every branch yourself from lecture slides or a textbook. DeckOwl starts from your own material instead: upload the document and the AI proposes a central topic, main branches, and sub-points joined by lines, ready to edit.
- Branches that show how one idea leads to the next
- Editable after generation, so you can rename, move, or add nodes
- Works from PDF, DOCX, PPTX, plain notes, and photos of pages
- Free plan includes 3 generations per month and study in the browser
Lines that link ideas
Each branch connects to its parent with a line, so the hierarchy is visible at a glance.
Editable after generation
Rename, move, or add branches once the map is built, then click through sub-topics as you study.
Built from your material
Upload PDFs, DOCX, PPTX, plain text, or a photo of a page, and the map follows the structure of your source.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, text file, or a photo of a page.
Generate the map
The AI pulls out the central topic, main branches, and sub-points, and draws them as connected lines.
Edit and study
Adjust any branch, explore the map, or turn the same material into flashcards and quizzes.
If you prefer paper, you can sketch the generated map by hand, since the structure is already sorted for you. Working from a finished map also shows which branches are thin, so you know where to add detail before an exam.

Frequently asked questions
How many branches should a mind map for geometry lines have?
Aim for four to six main branches, one for each line type or property you need to remember, with two to four sub-points under each. Too many branches make the map hard to scan.
How do I study parallel and perpendicular lines?
Draw each pair on a coordinate plane, compare their slopes, and practice spotting them in angle pairs formed by a transversal. Quiz yourself until you can name the relationship from a diagram alone.
Is there a free plan?
Yes. The free plan includes 3 generations per month and lets you study in the browser. Exports such as PDF, DOCX, Anki, and CSV are part of Plus, which costs $39/year or $7.99/month.
Do I need a credit card to start?
No credit card is needed to start. Students get 40% off with a school email.
