Turn your notes into a mind map you can use on Android tablets
Upload a PDF, DOCX, PPTX, plain notes, or a photo of a page, and DeckOwl builds an editable, explorable mind map. It runs in your tablet's browser, so there is nothing to install.
Why a mind map works well on a tablet
Studying on an Android tablet suits visual learners who want a mind map app for Android tablets that shows how ideas connect. A tablet's larger screen makes it easier to follow branches across a whole chapter than a phone does.
- Works from PDF, DOCX, PPTX, plain notes, and photos of pages
- Editable branches you can reorganize as your understanding grows
- Explorable maps that open up one section at a time
- A free plan to start with no credit card needed
Built from your own material
Upload a PDF, DOCX, PPTX, notes, or a photo of a page. Text in photos is read with text recognition.
Editable and explorable
Rearrange branches, expand sections, and explore the map at your own pace instead of reading a static image.
Works in the tablet browser
Open DeckOwl in Chrome or another Android browser and study without downloading a separate app.
How it works
Add your notes
Upload a file or take a photo of your class notes or textbook page.
Generate the map
DeckOwl turns the material into a mind map with main branches and sub-points.
Edit and study
Adjust branches on your tablet, then turn the same material into flashcards or a quiz.
A mind map is most useful when the branches come from your own material. DeckOwl reads your PDF, slides, or notes and sorts the content into main topics with supporting points, so you can spend your time checking and questioning the connections rather than drawing the layout from scratch.
Once the map is built, you can turn the same content into flashcards with spaced repetition or a quiz with explanations. The free plan includes 3 generations a month and studies in the browser.

Frequently asked questions
How do I organize a mind map for a long chapter?
Start with the chapter's headings as main branches, then add the key terms and examples under each one. Keep each branch to a few sub-points so the map stays readable on a tablet screen.
How many branches should a study mind map have?
Most useful maps have 4 to 8 main branches, each with 2 to 4 sub-points. If a branch grows beyond that, split it into two related topics.
Does DeckOwl work on an Android tablet?
Yes, DeckOwl runs in the browser, so you can open it in Chrome or another Android browser on your tablet. You do not need to install a separate app.
Can I export my mind map?
Exporting is a paid feature, and the free plan studies in the browser without exports. Plus is $39 a year or $7.99 a month, and Pro is $14.99 a month.
