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.

One file	The entire app is one HTML file — no install, no build, no dependencies.
Offline, always	It runs from file://. Nothing leaves your machine.
Bought once	No subscription, no account, no telemetry, no expiry.
83 templates	Business Model Canvas, Lean Canvas, OKRs, roadmaps, agent specs… all of them
It leaves the building	PNG posts, carousel PDFs, MP4 flythroughs, or one .html file that carries the app and the map together.
Claude writes into it	The connector below is free with every licence.

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

Skill	What it does
ma-cartographie-du-travail	A 15-minute interview that maps how you actually work — your processes, their hours, and where AI gives time back. Ends with the number: hours per week you get back.
atelier-vision-okr	Facilitates a team session — vision, mission, pillars, OKRs per department, plan for the year — then writes it as a canvas you can present.

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.
