Turn your notes into a mind map right in your browser
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page, and DeckOwl builds an editable mind map you can explore branch by branch.
Why a browser mind map maker helps when you study
Lecture notes often arrive as a long PDF or a pile of slides, and a flat list hides the connections between ideas. A browser-based mind map maker turns that material into a branching map you can open on most computers without installing software.
- Works in a normal browser tab with no download required
- Maps update when you edit branches, so you can refine them as you learn
- Photos of printed pages are read with text recognition
- Start free with three generations per month and no credit card
No install needed
Open a tab and start. The free plan runs the mind map right in your browser.
Editable branches

How it works
Add your material
Upload a PDF, DOCX, PPTX, plain text, or a photo of a page.
Generate the map
DeckOwl builds a mind map with main branches and sub-points.
Explore and edit
Collapse, expand, and adjust branches in the browser.
DeckOwl reads your file, groups ideas under main branches, and produces an editable map. You can rename nodes, reorganize branches, and explore the map one section at a time, which suits review before an exam.
The free plan lets you study in the browser with three generations per month. Paid plans add unlimited generations and file export options, so you can take your study material into other tools when you need to.

Frequently asked questions
How do I study from a mind map instead of rereading notes?
Cover the sub-points of one branch and try to recall them from the main topic. Then check the map and redo the branches you missed.
How many main branches should a study mind map have?
Most topics work well with five to seven main branches, each holding two to four sub-points. If a branch grows much larger, it probably needs its own map.
Is the browser mind map maker free?
Yes, the free plan includes three generations per month and studying in the browser. File exports such as PDF and DOCX are part of Plus, which costs $7.99/month or $39/year.
Can it map notes from photos of pages?
Yes, photos of pages are read with text recognition, so you can build a map from notes you photographed.
