Mind map software for PC that starts in your browser

A student with a messy lecture file and a deadline often needs mind map software for PC that can read that file instead of starting from a blank canvas. DeckOwl takes the document you already have and turns it into a branching map of the main topics and the details under each one.

Works in a browser on a PC, so you can study from a laptop or desktop without a separate program to manage.
Reads PDFs, DOCX and PPTX files, plain text notes, and photos of pages.
Keeps the map editable so you can correct or reorganize branches after generation.
Lets you expand and collapse branches to move between the big picture and the details.

Generate the full set

Starts from your material

Feed in a textbook chapter, lecture slides, or a photo of handwritten notes and the map is built from that content.

Editable branches

Rename, move, or remove branches so the map matches how you think about the topic, not just how the AI first sorted it.

Explorable structure

Expand and collapse branches to focus on one section at a time, which keeps long topics readable on a laptop screen.

How it works

Upload your file

Add a PDF, DOCX, PPTX, plain text, or an image of a page. No credit card is needed to start.

Generate the map

DeckOwl reads the material and organizes the main concepts into a branching mind map.

Edit and explore

Adjust the branches, expand the sections you need, and study the map in your browser.

Because the map is generated from your own material, it reflects your course rather than a generic template. You can then edit the branches, reorder them, and expand only the sections you are studying that day.

The free plan covers three generations per month and studying in the browser. Paid plans add unlimited generations and export options for sharing or reuse.

Frequently asked questions

How many branches should a mind map on Greek mythology have?

Start with five to seven main branches, such as gods, heroes, wars, and myths of creation, and keep sub-points to three or four under each. A map that is too wide becomes hard to review, so split very large topics into separate maps.

What is a good way to study Greek mythology with a mind map?

Cover one branch at a time and say the connections out loud, such as how Zeus's family ties link to the Titanomachy. Then cover the map and rebuild it from memory to find the gaps.

Is DeckOwl free to use on a PC?

Yes, the free plan includes three generations per month and studying in the browser, and no credit card is needed to start. Export options are part of the paid Plus and Pro plans.
