Notion Mind Map Maker

Notion has no built-in mind map, but it draws Mermaid diagrams from a code block. Type an indented list — get the code, paste it into Notion, done. Nothing you type leaves your browser.

How to paste it into Notion

  
    
    
  1. In a Notion page type /code and press Enter to add a code block.
    2. 
    
  2. Click the language name in the block’s corner and choose Mermaid.
    3. 
    
  3. Paste the code. Switch the block view to Preview or Split to see the diagram.
    4. 
  

  
If the mind map doesn’t renderMermaid’s mindmap type is newer than its classic diagrams, and Notion renders the Mermaid version it ships. Pick “Tree → right” or “Tree ↓ down” above: the same branches in the older flowchart syntax that always works.


  
What a Mermaid mind map can and can’t do

  
It is a static picture of a list: quick to make and easy to edit as text, but its nodes are not links to your Notion pages. If you want a map of how your pages actually connect — backlinks, relations, mentions — that map can be built automatically from the workspace itself.

FAQ

  
Is this tool free? Do I need an account?
Free, no account. The code is generated in your browser; your text is not sent anywhere.

  
How do I write the outline?
One idea per line. Indent a line (spaces or Tab) to make it a branch of the line above. Bullets like “-” or “1.” and Markdown headings are understood too, so you can paste a list from Notion or a doc.

  
Can I change the diagram after pasting it into Notion?
Yes — it is plain text in a code block. Edit the lines in Notion, or come back here, change the outline and paste the new code.

  
Can Notion build a mind map of my real pages?
Not by itself. IVGraph connects to your workspace and draws every page, backlink and database relation as an interactive 3D graph — no outline to type.
