Three steps to done
Upload a source
Add a PDF, slide deck, video, or article. Long, dense material is exactly what mind maps are for.
Generate the map
Memo identifies main themes, sub-topics, and the relationships between them, then lays everything out as a navigable map.
Explore and expand
Drill into branches, expand details on demand, and jump back to the underlying source whenever you need the full context.
Everything included
Automatic concept extraction
No blank canvas: Memo reads your material and drafts the hierarchy for you, from central ideas down to supporting details.
The big picture at a glance
See an entire chapter, paper, or course on one screen — ideal for spotting structure that linear notes hide.
Connected to your sources
Every branch traces back to the material it came from, so the map is a navigation tool, not just a pretty picture.
Pairs with the rest of Memo
Generate notes, flashcards, and practice tests from the same sources — the mind map shows the structure, the rest builds mastery.
Works with any subject
From anatomy to case law to system architecture — if it has structure, Memo can map it.
Common questions
Is the AI mind map maker free?
Yes. Memo has a free forever plan that includes AI mind map generation. Paid plans add higher monthly volume and larger uploads.
What can I turn into a mind map?
PDFs, lecture slides, YouTube videos, websites, and pasted text. Memo extracts the concept hierarchy from whatever you upload.
How is this better than drawing mind maps manually?
Memo builds the first draft in seconds by reading your material, so you spend your time understanding relationships instead of arranging boxes. Branches stay connected to the underlying sources.
Can I use the mind map to study?
Yes. Mind maps live alongside notes, flashcards, and practice tests generated from the same sources, so you can move from the big picture to active recall in one workspace.
