Why a phone-friendly mind map starts with your own notes

A mind map phone app is most useful when it starts from the pages you already have, not from a blank canvas. Photograph a chapter or upload your lecture notes, and the map follows the structure your teacher used.

Works from PDFs, DOCX, PPTX, plain text, and photos of pages
Editable maps so you can correct the AI's grouping
Explorable branches that keep long chapters manageable
Free plan includes 3 generations per month with browser study

Generate the full set

Photos of pages

Photograph printed pages with your phone and the text is read with text recognition, so you can map without retyping.

Editable branches

Rename, move, or add branches after the map is generated so it matches how your course organizes the material.

Explorable structure

Expand and collapse sections to focus on one topic at a time instead of scanning a crowded page.

How it works

Add your material

Upload a PDF, DOCX, PPTX, plain text, or photos of your pages from your phone.

Generate the map

DeckOwl organizes the main ideas into a mind map with branches and sub-points.

Edit and explore

Adjust the branches, then work through the map and turn sections into flashcards or quizzes.

Mind maps help most when you can change them. Move a weak branch, add a missing detail from class, and keep the version you will review before an exam. Those edits matter more than a perfect first draft.

Once the map is done, use its branches as study prompts. Say each sub-point from memory, then check it against the source.

Frequently asked questions

How do I make a mind map from lecture notes?

Paste or upload your notes, then review the main branches the AI creates. Rename any branch that does not match your lecture headings and add missing details before you study.

What is the best way to study with a mind map?

Cover the sub-points and recall each branch from memory, then check your answer against the source. Repeat the weakest branches a day or two later to strengthen recall.

Can I edit the mind map after it is generated?

Yes, mind maps are editable and explorable, so you can adjust branches after generation. The map is built from your own material, so you can always check it against the original pages.

Is DeckOwl free to try?

The free plan includes 3 generations per month and studying in the browser, with no credit card needed to start. Exports such as PDF and DOCX are part of the paid Plus plan.
