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:
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.
