What it is

TabTree is a mind-mapping and whiteboard app that fits in a single HTML file. You double-click it and it runs — offline, with no account, no server and no subscription. One document reads six ways: mind map, kanban board, Gantt chart, page of notes, spreadsheet or full-screen presentation. Switch views; nothing is converted and nothing is lost.

This repository

TabTree itself is a commercial product and its source is not published here. This repository is the public face of it, and it holds four things that are genuinely useful on their own:

• mcp/ — the full source of the Claude connector, free to use, copy, redistribute and modify (its own licence, no attribution required), and the same code published to npm as tabtree-mcp.

• plugins/tabtree/ — a Claude Code plugin: two facilitation skills that end in a real document, plus the connector. See Claude Code plugin below.

• templates/ — the 83 template outlines in plain Markdown, each with a link that opens it live. Paste them into TabTree, or into any outliner.

• screenshots/ — rendered by the real engine, not mocked up.

To use the app itself, try the demo — it is the whole application, running in your browser, with nothing to install.

Claude connector

Let Claude read your TabTree library and turn a conversation, a transcript or a spec into a real map on your disk. Local files, no account, nothing uploaded — the connector only ever sees the backup folder you point it at.

Claude Desktop — double-click, nothing to install. Download TabTree-Connector.mcpb and double-click it. Claude Desktop ships its own Node, so there is nothing else to install, and it asks you for your backup folder in a normal folder picker.

Claude Code, or any MCP client — one line:

npx -y tabtree-mcp

Or in your client's config:

{
  "mcpServers": {
    "tabtree": {
      "command": "npx",
      "args": [
        "-y",
        "tabtree-mcp"
      ],
      "env": {
        "TABTREE_DIR": "/path/to/your/TabTree/backup/folder"
      }
    }
  }
}

Six tools: list_maps, read_map, search_maps, create_mindmap, create_board, propose_changes. It only ever writes new files — it never modifies or deletes one of your maps, and propose_changes drops a proposal the app applies only when you click. Full detail in mcp/README.md.

Claude Code plugin

Two skills that do not end in advice — they end in a document on your disk.

/plugin marketplace add ai4xedu/tabtree-mcp
/plugin install tabtree@tabtree

Both are written in French: they were built to run real workshops, and that is the language they run in. They read and reply in French; the documents they produce follow the map's own language.

One of them needs a folder, the other does not. ma-cartographie-du-travail writes nothing — it hands you a readable brief and a JSON block — so it works the moment you install it. atelier-vision-okr calls the connector to write the canvas, so it needs TABTREE_DIR pointing at your TabTree backup folder — the one you picked with 🛟 on the My maps screen:

export TABTREE_DIR="/path/to/your/TabTree/backup/folder"

There is no auto-discovery: without that variable the connector says so plainly rather than guessing a folder. If you only want the connector and not the skills, the double-click .mcpb bundle is the better route — it asks for the folder in a normal picker.

Screenshots

The same document as status columns — every card is still a node of the map.

Arrows stay attached to the boxes when you move them.

A map sent as one .html file: your reader double-clicks it, offline, no install.

Images and reasoning on one canvas.

Radial layout, dark theme.

Licence

Three different licences, and the distinction matters:

• The connector in mcp/ is free to use, copy, redistribute and modify, for any purpose, with or without a TabTree licence — see mcp/LICENSE.md. It is given away on purpose.

• The skills in plugins/tabtree/ are free on the same terms, commercial workshops included — see plugins/tabtree/LICENSE.md. They are a separate licence because the connector's own text says it covers the connector only.

• The app is a commercial product sold at tabtree.app; its source is not in this repository, and its licence does not allow redistribution.

• The template outlines are yours to copy and adapt freely.
