Using a mind map app on your PC for study
Most students who search for a mind map app for PC want something they can open at a desk and use for real coursework, not a one-off diagram. DeckOwl runs in your browser, so it works on any PC with a modern browser. Upload a file or a photo of your notes and it builds a map with a central topic and sub-points you can edit.
- Upload PDFs, DOCX, PPTX, plain notes, or photos of pages
- Edit branches and expand topics to explore the structure
- Study the map in your browser on your PC
- Upgrade to Plus for unlimited generations and exports
Editable branches
Rename, move, or delete any branch so the map matches how your course is organized.
Explorable structure
Expand and collapse topics to focus on one area at a time without losing the big picture.
Works from your own material
Start from a PDF, DOCX, PPTX, plain notes, or an image of a page read with text recognition.
How it works
Upload your notes
Add a PDF, Word or PowerPoint file, pasted notes, or a photo of your page.
Review the generated map
Check the central idea and main branches against your source and fix anything that looks off.
Edit and explore
Add detail where the lecture was thin, then expand each branch to test what you remember.
Mind maps work best when you can see how a subject breaks down. Begin with one central idea, check each branch against your source, and add detail where your notes were thin. The free plan includes 3 generations per month, and exports are part of Plus.

Frequently asked questions
How do I organize acids and bases in a mind map?
Start with the three main definitions, Arrhenius, Brønsted-Lowry, and Lewis, as main branches. Under each, add the key idea and one example such as HCl or ammonia.
How many branches should a chemistry mind map have?
Keep it to five to seven main branches so the structure is easy to hold in memory. Split a branch further only when a sub-topic has its own rules, like strong versus weak acids.

Yes. The free plan includes 3 generations per month and studying in the browser. Exports are a paid feature on Plus.
