# TabTree > A mind-mapping and whiteboard app that runs in the browser and installs as an > app. One document reads six ways — mind map, kanban board, Gantt chart, page of > notes, spreadsheet or presentation — and everything keeps working offline. > Free plan with an account; Pro is a subscription with a 14-day trial. TabTree opens .xmind, Markdown and OPML files, exports PNG/PDF/Markdown, and can send a whole map as one .html file that opens on any computer with no install. Maps can also be published to a link. The app ships with 87 templates, including well-known frameworks (Business Model Canvas, Lean Canvas, Value Proposition Canvas, SWOT, AARRR, 1-Page Marketing Plan) and an AI pack. Any template can be opened directly with `https://tabtree.app/tabtree-demo.html?embed=1&tpl=`. ## Pages - [TabTree — mind maps, whiteboards, kanban and Gantt in one document](https://tabtree.app/): One document reads six ways: mind map, kanban board, Gantt chart, page of notes, spreadsheet or presentation. Free plan, Pro subscription, works offline — and you can email a whole map with the app inside it. - [How to use TabTree](https://tabtree.app/how-to/): The guide: backup folder, restoring, sharing a map, keyboard shortcuts. - [Learn TabTree — ten short modules](https://tabtree.app/learn/): The course: set the sync folder up once, read one map as a kanban and a Gantt, publish a link anyone can open. Each module ends with a map you make yourself. No video. - [Ten rules for using TabTree without losing anything](https://tabtree.app/learn/rules/): Where the sync folder goes, why an empty library is not lost maps, what beats what in a conflict, and the 90-day clock on a published link. - [Sync your mind maps between computers — the TabTree folder](https://tabtree.app/learn/folder/): TabTree has no server: it writes one .tabtree file per map into a folder you choose. Put that folder inside iCloud, OneDrive, Dropbox or Syncthing and the library follows you. Ten minutes, once. - [My mind maps disappeared — conflicts, trash and the empty library](https://tabtree.app/learn/recover/): An empty library is almost never lost maps. What an empty shelf means, what a (folder copy) is, where a deleted map waits, and why an edit always beats a deletion. - [Publish a mind map to a public link](https://tabtree.app/learn/publish/): Turn a map into a link anyone can open with no account and no install. What the link carries, why republishing keeps the same address, the 90-day clock, and the published-page allowance per edition. - [Getting started with TabTree — the two doors and your first map](https://tabtree.app/learn/start/): One licence, two ways in: the hosted app and a single file on your disk. Why installing it retires a daily click, and the three keys that are the whole editor. - [Turn a mind map into a kanban and a Gantt — one document, five views](https://tabtree.app/learn/views/): The kanban and the Gantt are not exports: they are the same map, and nothing is converted. Tick a node to make it a task, date it to put it on the timeline. - [Open .xmind, Markdown, OPML, Excel and Trello files in TabTree](https://tabtree.app/learn/import/): Drag an .xmind file in and watch it open. Markdown, OPML, CSV, Excel and Trello exports come in too — nothing is uploaded, the file is read in your browser. - [The 69 TabTree templates — which one, and when it is the wrong tool](https://tabtree.app/learn/templates/): Eighty-seven templates in thirteen families, and the paragraph most galleries leave out: when a famous framework is the wrong shape for your question. - [Run your week from a mind map — tasks, gauges and time](https://tabtree.app/learn/week/): Tick a node and it feeds the kanban and the gauges. Filter by branch, track time per column, export the actions on their own, and a Monday-to-Friday rhythm that survives a busy week. - [Export a mind map as an image, a PDF, Markdown — or a file with the app inside](https://tabtree.app/learn/export/): PNG, PDF, Markdown, CSV — and the one nobody expects: a single .html file that opens your map on any computer with nothing installed, and never expires. - [Password-protect a shared map, capture emails, publish a whole folder](https://tabtree.app/learn/protect/): A passphrase in front of the page, visitors who leave their email to open it, and a whole library published at one address — a lead magnet with no website. - [Leaving XMind](https://tabtree.app/leave-xmind/): For people paying an XMind subscription: drop a .xmind file into the browser and watch it open. - [Business frameworks you can actually fill in](https://tabtree.app/frameworks/): Business Model Canvas, Lean Canvas, Value Proposition Canvas, SWOT, AARRR, the 1-Page Marketing Plan, OKRs and more — each as an editable document rather than a PDF, with a note on when it is the wrong tool. - [Business Model Canvas — the nine blocks, editable in your browser](https://tabtree.app/frameworks/business-model-canvas/): Each block with the question it really asks and the way it gets filled in badly, a worked example, and the canvas editable in the page. Includes how to adapt it to marketplaces, free tiers and non-profits. - [Lean Canvas — the nine blocks, editable in your browser](https://tabtree.app/frameworks/lean-canvas/): Problem first, and why four blocks differ from the Business Model Canvas. Each block with the trap in it, a worked example, the canvas editable in the page, and when to stop using it. - [AI adoption framework — a template you can actually fill in](https://tabtree.app/frameworks/ai-adoption/): The framework as a working document: task inventory, scoring, two pilots, the rules of the game. Editable in the page, no account. - [AI usage policy template — the eight sections, editable in your browser](https://tabtree.app/frameworks/ai-policy/): Approved tools, what may never be pasted, who owns the output, disclosure, incidents and the six-month review — each with the trap in it. Editable in the page, no account. - [TabTree press kit — facts, boilerplate, screenshots](https://tabtree.app/press/): For journalists and directories: the facts, three lengths of boilerplate, what ships in the file, what the product is NOT, and six screenshots rendered by the real engine.
