A mind map shows how the ideas in a topic connect: one subject in the middle, the big themes branching off it, and the details under each. This AI mind map maker builds that structure for you from your notes, a PDF or just a topic name.
How to make a mind map with AI
Give it a source
Upload a PDF, DOCX, TXT or MD file, paste your notes, or paste an article link. Or switch to Ask AI and type a topic, like "the French Revolution".
Generate the map
Hit Make my mind map. The AI finds the main subject, splits it into 4 to 7 main branches, and fills each branch with 2 to 5 sub-branches.
Read it top down
Start with the main branches to get the big picture, then go into each one. Afterwards, try redrawing the map from memory. It's a great self-test.
Example: the causes of World War I
Main branches on the left, their sub-branches on the right, in the format the tool builds.
- Alliances
- Triple Entente · Triple Alliance · Treaties that pulled allies into war
- Militarism
- European arms race · Anglo-German naval race · Mobilization plans
- Imperialism
- Competition for colonies · Moroccan crises of 1905 and 1911
- Nationalism
- Pan-Slavism in the Balkans · Serbia vs Austria-Hungary
- The spark
- Franz Ferdinand assassinated, June 1914 · The July Crisis
What people use it for
Seeing a whole chapter at once
Get the structure of a chapter before you dive into details. Facts are easier to learn when you know where they fit.
Planning an essay or a revision session
The main branches make a ready outline: one section, or one study block, per branch.
Untangling messy notes
Paste notes that jump around and see them sorted into themes.
What you get
One root, the subject. 4 to 7 main branches, each with 2 to 5 sub-branches, and a third level only where it really helps. Every label is short, six words at most, so the map stays readable.
The map shows up as a branching tree you read from top to bottom, with each level indented under its parent. When you give it your own material, the AI is told to use only that material. Each run reads up to about 15,000 characters, roughly 2,500 words.
Can ChatGPT make a mind map?
It can write one out as a nested list if you ask the right way. Here there's no prompt to write and no formatting to fix: you get the structure as a clean tree, ready to study from.
If you want more than a map, the full lezrn app turns your material into a course with lessons, quizzes, flashcards and mind maps, and schedules reviews so you keep what you learned.
Frequently asked questions
Is this AI mind map maker free?
Yes, with a free lezrn account. A free account gets a few free runs every day.
Can I make a mind map from a PDF?
Yes. Upload a PDF with selectable text. Scanned pages don't work, since they have no text to read. For a long document, split out one chapter so the map covers it properly.
How big is the mind map?
4 to 7 main branches, each with 2 to 5 sub-branches. Big enough to cover a chapter, small enough to hold in your head.
Can I edit or download the mind map?
Not in the free tool. You read the map on the page. If you want to keep it, copy the text or take a screenshot.
Are mind maps good for studying?
They help most with seeing how ideas relate, which is great early on and when you plan. For remembering details, pair the map with self-testing, like a quiz or flashcards on the same material.
Can I make a mind map from a YouTube video?
Yes. Paste the YouTube link once you are signed in to your free lezrn account. A file, pasted text or a web article link work too.
