How a text-based mind map helps you study

Good notes often hold the ideas you need in the order your teacher taught them, which is not always the order you will be tested on. A mind map generator based on text reorganizes that material around its main ideas, so you can see how the pieces connect before you memorize anything.

Works with pasted text, PDFs, DOCX, PPTX, and photos of pages
Branches stay editable, so you can correct the structure yourself
Good for reviewing a chapter's big picture before testing yourself
Free plan includes 3 generations per month, with study in the browser

Example photosynthesis mind map branches (general biology)

Light-dependent reactionsOccur in thylakoid membranes · Use light to split water · Produce ATP and NADPH

Calvin cycleTakes place in the stroma · Fixes CO2 into sugar using RuBisCO · Uses ATP and NADPH from the light reactions

ChlorophyllGreen pigment in thylakoids · Absorbs mostly red and blue light · Reflects green light

StomataPores on the leaf surface · Let CO2 in · Release water vapor and oxygen

Overall equation6 CO2 + 6 H2O + light → C6H12O6 + 6 O2 · Glucose is the sugar produced · Oxygen is released as a byproduct

Reads many formats

Upload PDF, DOCX, PPTX, plain text, or a photo of a page. Photos are read with text recognition.

Editable branches

Rename, move, or delete any branch so the map matches how you think about the material.

Explore by clicking

Open each branch to see its sub-points, then move through the map one idea at a time.

How it works

Add your text

Paste your notes or upload a file from your own course material.

Generate the map

DeckOwl pulls out the main ideas and groups supporting points under them as branches.

Edit and explore

Adjust the branches and click through them to check what you understand.

Because the map comes from your own material, it reflects your course rather than a generic outline. You can edit any branch that looks wrong, then open the map branch by branch as a quick review before an exam or a reading quiz.

Mind maps work best alongside active recall. Use the branches to pick topics for flashcards or quiz questions, and return to the map when you need the big picture again.

Frequently asked questions

How do I study photosynthesis for a biology exam?

Start with the overall equation, then learn the light-dependent reactions and the Calvin cycle as two linked stages. Build a mind map with one branch per stage, and quiz yourself on where each input and output goes.

Can I turn lecture notes into a mind map?

Yes. Paste plain text or upload a PDF, DOCX, PPTX, or a photo of your notes, and the tool arranges the main ideas into branches. You can then edit those branches and explore them by clicking through each one.

Is the mind map generator free?

The free plan includes 3 generations per month and lets you study in the browser, but exports are not included. Exports come with Plus at $7.99 per month or $39 per year, and Pro adds stronger AI and bulk upload.

Do students get a discount?

Yes, students with a school email get 40% off. You do not need a credit card to start.
