Open source or not, pick the tool that fits your study workflow

Many students searching for an open source mind map maker care about two things: being able to see and change how the software works, and having a map that reflects their own course material. DeckOwl covers the second need well, but it is not open source, so it will not satisfy a strict requirement for open code.

Editable mind maps

Rename, move, and restructure branches after generation so the map matches how you think about the material.

Explorable structure

Expand and collapse branches to move from the main idea down to supporting details without losing the overall shape.

Works from your own files

Start from lecture slides, reading PDFs, or handwritten notes photographed with your phone instead of a generic template.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes, or a clear photo of a page. Photos are read with text recognition.

Generate the mind map

DeckOwl organizes the content into a main topic with branches and sub-points you can edit.

Edit and explore

Adjust branches, expand the areas you need to review, and study the map in your browser.

If you need source code access, self-hosting, or a license you can audit, look at dedicated open source mapping projects. If you mainly want an editable map built from your lecture notes and readings, DeckOwl generates one from your uploads and lets you reshape it afterward.
