Everything it does, and the keys to drive it.

One file, two views

• Any .md opens as a mindmap

  Headings become branches and list items become leaves, laid out automatically. No import and no conversion — you are looking straight at the file.

• Edits sync both ways

  Change the map and the Markdown updates; change the text and the map follows. Edits from another pane, a script, or an AI assistant appear as they land.

• The file is the source of truth

  Every change writes back to the plain .md and saves at once. No sidecar database, no proprietary format — what you see is what is on disk.

• Flip between map and source

  Switch the same file between the mindmap and the raw Markdown from the editor title bar — one document, shown two ways, never a copy that can drift.

• A title at the centre

  When a note has a single top-level # heading, it becomes the centre node, so the map opens around its subject instead of an empty root.

• Frontmatter is preserved

  YAML frontmatter at the top of the file is kept verbatim through every edit, so tags and metadata your other tools rely on survive untouched.

What a node can hold

Nodes are real Markdown, so they render the Markdown you already write — right inside the map.

• Formatting & links

  Bold and italic render in place, and [text](url) links are clickable straight from a node.

• To-do checkboxes

  A - [ ] or - [x] item becomes a checkbox you can tick on the node — tasks live in the same map as your thinking.

• Inline images

  Local images embedded in a node show inline; click to open them full size. Obsidian-style alt|width sizing hints are honoured.

• Code blocks

  Fenced code blocks attach to their heading and render as a formatted code panel inside the node — snippets stay where they belong.

• Mermaid diagrams

  A ```mermaid block renders as a live diagram — flowcharts, sequences and more — themed to match, with click-to-zoom.

• Tables

  GitHub-style pipe tables render as real tables inside a node, with a zoom view for the wide ones.

• Math

  LaTeX math renders with KaTeX, so formulae appear typeset rather than as raw $…$ source.

• Notes under a point

  Indented prose beneath a bullet is kept as that node’s body, so a leaf can carry a sentence of detail without cluttering the branch.

Keyboard & mouse

Select a node, then drive the whole map without reaching for the mouse.

Shortcuts act on the current selection and pause while you are typing in a node.

Yours, everywhere

• Local-first, fully offline

  No account, no sign-in, no network calls, no telemetry. The extension never sends your Markdown anywhere. See the privacy policy.

• Works with your tools

  It is plain Markdown: commit it to git, open it in any editor, and let Claude Code or Copilot read and write it directly — the map just stays in sync.

• Recolour to taste

  One considered theme out of the box, nothing to configure. A small control re-tints the five branch colours to match your brand, with one click to reset.

• Cross-platform

  Runs wherever VS Code does — Windows, macOS and Linux, on version 1.85 or newer. One install, the same map everywhere.
