How a concept map app turns your notes into a study map

A concept map app helps when a unit has too many names, dates, and links to hold in your head at once. Upload a PDF or photos of your notes, and DeckOwl builds a mind map that groups related ideas under clear main branches.

See the central idea and its main branches at a glance.
Edit nodes and links so the map matches your lecture.
Explore branches one at a time instead of rereading the whole chapter.
Start on the free plan with three generations per month and study in the browser.

Generate the full set

Map from your own material

Start from your PDF, DOCX, PPTX, plain text notes, or photos of pages. Text recognition reads the pages so the map reflects your course, not generic content.

Editable branches

Rename nodes, move branches, and delete anything that does not belong. The map is a working draft you shape as you learn the material.

Explore at your own pace

Open a branch to see its sub-points, then collapse it when you are done. Use the map as a study overview before you move on to flashcards or a quiz.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file, or photos of your pages. No credit card is needed to start.

Review the generated map

Check the central idea and the main branches. Edit any labels that do not match your lecture.

Explore and study

Click through branches to test your recall, then build flashcards or quizzes from the same material.

Once the map exists, you can reshape it. Move branches, rename nodes, and remove what you do not need, so the map reflects how your course actually organizes the material.

Frequently asked questions

How do I start a concept map for a reading on Greek myths?

Write or name the central figure or theme in the middle, then add main branches for gods, heroes, and major events. Use short labels and link related ideas so the connections are visible.

How many branches should a concept map have?

Most useful maps for a single chapter have five to seven main branches, each with two to four sub-points. Fewer branches make the map easier to scan during review.

The free plan includes three generations per month and lets you study in the browser. You can test it with a real set of notes before deciding whether to upgrade.
