MindmapMD

Your mindmap is just Markdown.

Edit it in VS Code or on the web, share it with a link, take the plain .md anywhere. Open any .md and the map is the editor — Tab branches, type to name a node, Enter adds a sibling, drag to re-parent. Every change writes straight back to the file, and any edit to the file redraws the map. No proprietary format, no lock-in.

A mindmap built live in VS Code — from the title "Kyoto trip", five colour-coded branches (See, Eat, Do, Go, Plan) and their nodes are typed out, a photo is pasted straight onto a node, then the finished map is flipped to its plain-Markdown source

The map is the editor

No split screen, no preview pane — the mindmap is the editor, and the .md file is the only artifact.

Tab adds a child · Enter a sibling · Space edits a node
T cycles to-do state · \ folds a branch · arrow keys navigate
Click selects, double-click edits, drag to move a branch, drop a file onto a node to attach it

It's just Markdown

No lock-in. Your mindmap is one plain .md file — no proprietary format, no export. Any editor, any OS, Git-friendly forever.
Your AI tools already work on it. Let the AI tools in your editor read and rewrite the file — the map reflows the moment it's saved.
Rich content inline. Tasks, links, images, tables, fenced code, Mermaid, and KaTeX ( $…$ , $$…$$) all render inside nodes.
Local-first & offline. Runs entirely on your machine — no analytics, no telemetry, no network calls. Your .md files never leave your computer.

Publish straight from the editor

Run MindmapMD: Publish Mindmap and get one link anyone can open — public or private, free. Publish again and the same link updates. Embed a live, interactive map in any page or doc, or download the Markdown back anytime and keep editing.

Publishing, embeds & the web editor → mindmapmd.app

Install

In VS Code, open the Extensions panel (Ctrl+Shift+X / Cmd+Shift+X), search for MindmapMD, and click Install. Or from the command line:

code --install-extension mindmapmd.mindmapmd

Use

MindmapMD: New Mindmap from the Command Palette opens a fresh map with an empty centre node — type your topic and start branching.
Or right-click any .md → MindmapMD: Open as Mindmap.
The title-bar icon flips between the mindmap and the Markdown source in the same tab.

The single top-level # heading becomes the centre node.
