Features

Everything you need to master your markdown

From a powerful Monaco editor to an AI assistant to a fully documented API — MarkdownTree is the tool you didn't know you were missing.

Graph Visualization

See every heading, paragraph, code block, and link as a navigable node in an interactive graph. Collapse subtrees, zoom, pan, and click to jump to source.

Monaco Editor

Full-featured markdown editor powered by Monaco — the same engine as VS Code. Syntax highlighting, auto-pairs, and live graph updates as you type.

AI Enhancements

Open the assistant panel to see model availability. Table-of-contents generation works deterministically; model-backed writing assistance shows an honest degraded state until configured.

Four View Modes

Switch between Editor, Graph, Split, and Preview. Resize panels freely. Toggle the document outline sidebar and minimap to fit your workflow.

Export & Share

Export to Markdown, clean HTML, or structured JSON. Copy a bounded URL-only share link when the document is safe to put in a URL.

MCP-Ready API

Public-safe parsing, graphing, outline, stats, export, and MCP introspection are available via a versioned REST API with OpenAPI docs.

How it works

Paste. Explore. Export.

01

Paste or write

Open the editor and paste your existing markdown, import a .md file, or start typing from scratch.

02

Explore the graph

Your document instantly becomes a zoomable, collapsible graph. Click any node to jump to it in the editor.

03

Export or share

Export to Markdown, HTML or JSON. Copy a shareable URL to send your document — no account required.

For developers

A fully documented REST API

Every feature is accessible via /api/v1. Transform markdown to graph JSON, generate outlines and stats, export HTML or JSON, and inspect model availability. OpenAPI spec live at /api/docs.

POST /api/v1/transform
{
  "content": "# Hello\n\n## World",
  "options": {
    "includeText": true,
    "direction": "RIGHT"
  }
}

// → 200 OK

FAQ

Common questions

What is MarkdownTree?

MarkdownTree is a visual markdown editor that transforms your documents into interactive graph visualizations, so you can see, navigate and understand document structure at a glance.

Is MarkdownTree free?

Yes, MarkdownTree is completely free and open source under the MIT license.

Does MarkdownTree store my documents?

The editor is browser-first. Non-sensitive local drafts are stored in your browser only, and public API requests process submitted Markdown without claiming server-side document storage.

What export formats does MarkdownTree support?

MarkdownTree supports export to Markdown, HTML, and JSON. PDF export and PNG graph export are scaffolded but unavailable in Phase 1, so the UI and API show degraded states instead of fake files.

Does MarkdownTree have an API?

Yes. MarkdownTree exposes public-safe REST endpoints at /api/v1 and JSON-RPC MCP tooling at /api/mcp. Future protected backend actions are scaffolded for PLATPHORM_API_KEY.
