Reading long material through a mind map
Students who need a mind map reader online usually have a stack of lecture slides or a long chapter and want the structure, not a wall of text. A map shows how the main claim connects to its evidence, which makes it easier to see what the author is actually arguing.
- Put the author's central claim at the top, then list the evidence under it.
- Mark unfamiliar terms as their own branches so you can define them later.
- Use one branch per section heading so you can find passages again quickly.
- Redraw the map after a second read to see what you now understand differently.
Readable from any source
Upload PDFs, DOCX or PPTX files, plain text notes, or photos of pages. Text recognition reads the photos so you can map them too.
Editable branches
Rename, move, or delete branches after generation so the map matches how your course organizes the material.
Explore at your own pace
Expand and collapse sections to read the big picture first, then drill into the details that matter for your exam.
How it works
Upload your reading
Add a chapter, lecture slides, or your own notes in PDF, DOCX, PPTX, text, or image form.
Generate the map
DeckOwl organizes the main ideas into branches and sub-points you can scan in seconds.
Read and edit online
Open the map in your browser, adjust anything that looks off, and use it as a study guide while you read.
Start by generating a map from your own reading, then check that each branch matches a section heading or a key idea. Remove anything that is just an example, and keep the terms you will need to define on the exam.
Because the map is editable and explorable, you can rebuild it after a second read-through. Adding your own questions to the branches turns a passive summary into something you can test yourself on.

Frequently asked questions
How do I read a long chapter faster with a mind map?
Skim the headings first, then build the map branch by branch as you read each section. A map of the chapter's structure gives you a fast review before an exam, and you can return to any branch when you need detail.
What should a mind map for reading comprehension include?
Include the main idea, the supporting details that back it up, the text structure (such as cause and effect or compare and contrast), and any terms you need to define. Keep each branch short enough to say in one breath.
Can I edit the mind map after DeckOwl creates it?
Yes. Every mind map is editable, so you can rename branches, move sub-points, and remove anything that does not match your course material.
Is the mind map reader free to use?
The free plan includes 3 generations per month and lets you study in the browser, but exports are not included. PDF, DOCX, Anki, and CSV exports are on the Plus plan, which costs $39 per year or $7.99 per month, and students get 40% off with a school email.
