Turn your notes into an editable online mind map
Upload a PDF, DOCX, PPTX, text notes, or a photo of a page and get a mind map you can rearrange and explore one branch at a time.
Why a structured map beats a wall of notes
Long lecture slides hide how ideas connect, and an online mind map shows that structure at a glance. DeckOwl builds one from your own PDF, DOCX, PPTX, text notes, or a photo of a page, so the map reflects what your instructor actually covered.
- Shows how concepts relate, not just a list of terms
- Works from your own PDFs, slides, and notes
- Editable branches so the map matches your course
- Switch any branch into flashcards or quiz questions
Built from your material
Start with your own lecture slides, reading PDFs, or typed notes. Photos of pages are read with text recognition, so handwritten-free printed pages work too.
Editable and explorable
Rename branches, move ideas around, and expand or collapse sections so you can focus on one topic at a time.
Study from the map
Turn any branch into flashcards with spaced repetition or into a quiz with explanations, all from the same source material.
How it works
Upload your source
Add a PDF, DOCX, PPTX, plain text file, or an image of your notes.
Generate the map
DeckOwl organizes the main ideas into a branching map with sub-points under each one.
Explore and edit
Reshape the map, expand branches, and save it to keep studying in the browser.
A map works best when you use it actively. Cover one branch, recall its sub-points from the central topic, then check yourself. Branches you miss can become flashcards or short-answer questions, which keeps the same material moving from overview to recall.
Because the map is editable, you can reorganize it as your course changes. Move a subtopic under a new heading, merge two related branches, or add your own notes next to the generated ones.

Frequently asked questions
What should a cell biology mind map include?
Start with the main organelles, then add each one's function and the key structures inside it. Connect related branches, such as how the endoplasmic reticulum and Golgi apparatus handle proteins.
How do I study from a mind map effectively?
Cover one branch and recall its sub-points from the central topic before you look. Then turn the branches you missed into flashcards so they come back on a spaced schedule.
Can I export my study material?
Exports are a paid feature. The Plus plan includes PDF, DOCX, Anki, and CSV export for $39/year or $7.99/month.
