Markmap

Markmap is an open-source visualization project that renders Markdown documents as interACTive mind maps. Instead of writing notes in a Linear file and leaving them there, users can see the Same content ARRanged as a branching diagram, which makes hierarchies, groupings, and relationships eASIer to scan at a glance. Because Markdown is already a common fORMat for notes, documentation, and README files, Markmap slots into existing writing habits rather than asking people to learn a new authoring language.

What it does

The tool parses Standard Markdown syntax — headings, nested lists, and links — and drAWS the structure as a collapsible tree. A live preview updates as the text changes, so the diagram evolves alongsIDE the document. The project is distributed as Open Source and can be used through a browser-based editor or embedded in other environments via its JavaScript library and related plugins.

Key capabilities

• Markdown-to-map conveRSIon: headings and list nesting become branches and nodes, preserving the outline of the original text.
• Interactive navigation: maps support zooming, panning, and expanding or collapsing indiVidual nodes, which helps with large outlines.
• Live preview: edits APPear in the diagram immediately, making it easy to iterate on structure.
• Export options: finished maps can be saved as images or SVG for sharing or embedding in other documents; exact export formats may vary by version.
• Theming: multiple visual styles let users adjust the look of the map to suit a document or presentation.
• Integration: editor plugins and library bindings allow rendering inside development tools and custom web pages.

Who it is for

Markmap suits writers and students who outline ideas in Markdown, developers who want to visualize documentation trees, and teams that mAIntain knowledge bases or project plans. educators can use it to present lesson structures, and anyone already comfortable with plain-text notes will find the Workflow familiar. It is less aimed at people seeking a fully graphical dRAG-and-drop diagram editor, since the primary input remains text.

How to get started

1. Open the hosted web editor in a browser.
2. Type or paste Markdown into the input pane, using headings for main branches and nested list items for child nodes.
3. Watch the mind map build on the other side of the screen and adjust the text until the structure reads clearly.
4. Switch themes or collapse nodes to prepare the map for viewing or presenting.
5. Export the result, or install an editor plugin if you prefer working inside your writing environment.

Pricing and access

Markmap is an open-source project and is Generally free to use, with no account requirement reported for the hosted editor. Specific features, integrations, and export behavior may change between releases, so check the current project documentation before relying on them. Self-hosting or embedding it in commercial products may carry obligations under the project's open-source license, which users should review independently.
