Turn your notes into a free mind map, no install needed
Skip the installer. Upload a PDF, DOCX, PPTX, or notes, and get an editable mind map you can explore branch by branch in your browser.
Why a browser-based map works better for studying
Most students who want to map out a chapter do not need another desktop installer, they need a map they can change as they learn. DeckOwl works as free mind map software right in the browser, so you can start from the material you already have.
- No download or install required, and it runs in any modern browser
- Upload PDFs, DOCX, PPTX, plain text, or photos of notes
- Edit and rearrange branches so the map fits your course
- Free plan includes 3 generations per month with no credit card needed
Nothing to install
DeckOwl runs in your browser on any computer with internet access, so there is no download, setup, or update to manage.
Editable, explorable maps
Expand and collapse branches, reword nodes, and reorganize the structure so the map reflects how you think about the material.
Built from your own material
Start from your lecture slides, textbook chapter, or photos of notes, and the map is built from that content rather than generic templates.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain text, or a photo of a page. Text in images is read with text recognition.
Generate the mind map
DeckOwl organizes the main topics into branches with sub-points. The free plan includes 3 generations per month.
Edit and explore
Reword nodes, rearrange branches, and expand each section to test yourself on what you understand before moving on.
A mind map only helps if the structure matches the material. Because you can edit every node, you can cut weak branches, merge overlapping topics, and add missing details after checking your notes against the source.
Exporting is a paid feature. The free plan lets you study in the browser, while Plus adds PDF and DOCX export along with unlimited generations.

Frequently asked questions
Do I need to download anything to make a mind map?
No. DeckOwl runs in your browser, so you do not install software. Exporting files is a paid feature, and Plus includes PDF and DOCX export.
How many branches should a study mind map have?
Five to seven main branches usually cover a chapter well. Each branch should hold two to four sub-points, and anything longer belongs in its own map.
How do I study from a mind map instead of just looking at it?
Cover the sub-points and try to recall each one from its main branch. Then check your notes and fix any gaps before moving on to the next section.
Is there a free plan, and what does Plus cost?
The free plan includes 3 generations per month and studying in the browser. Plus is $99.90 per year or $9.99 per month, and students get 40% off with a school email.
