A native macOS mind-mapping app with organic, hand-drawn branches, five layouts, and AI that turns a single prompt into a structured map. Offline-first. Keyboard-driven. No subscription — ever.
Eight features that make Lumitree different from every other mapping tool.
AI Generation
Type a topic — "Solar System", "Marketing Strategy", "World Cuisines" — and Lumitree generates a complete, multi-level map in seconds. Choose the structure, expand any branch, or refine it conversationally in the sidebar.
The details that make a tool feel complete.
⌘K opens a searchable list of every action, theme, and layout. Type a few letters, hit Return. No menus to memorize.
A collapsible text outline that mirrors your map. Click a row to select the node on the canvas. Great for long, deep maps.
A clickable, draggable bird's-eye view in the corner. Navigate large maps without zooming out. Click anywhere on it to jump.
Filter your map by Priority, Progress, or Depth. Dim everything except what matters. Switch lenses instantly from the toolbar.
Hold ⌘ and drag a node onto another to change its parent. The child keeps its position — only the connection moves. Cycle prevention built in.
Paste a multi-line outline and Lumitree offers to convert it into a branch structure. Tabs become depth levels. One shortcut, instant import.
Add emoji from a grid picker, set priority and status badges, attach multi-line notes to any topic. Rich metadata without visual clutter.
Start from a template: SWOT, project plan, weekly review, reading notes, decision matrix. Or save your own maps as templates.
Under 3 MB. Written in Swift and SwiftUI. Launches instantly, runs cool, never spins a fan. Apple Silicon native. Signed and notarized.
No account. No card. No trial timer. Just download and use it.
No. On macOS 26+ with Apple Intelligence, generation is free and on-device. If you want OpenAI or Claude, plug in your own API key — Lumitree calls them directly from your Mac. We don't proxy, store, or see your key.
Wherever you save them — the same way TextEdit or Pages saves a document. Plain .mindmap files on your disk. No account, no cloud, no sync service. You own the file.
Import: OPML, Markdown, FreeMind XML, multi-line paste. Export: PNG (2× Retina), PDF, SVG, OPML, Markdown, JSON. All exports are generated locally on your Mac.
Completely. Map creation, editing, layouts, themes, export — everything works without an internet connection. AI features need a network only if you're using Claude or OpenAI. Apple Intelligence runs on-device.
Lumitree is free during v0.x early access. When v1.0 ships, it becomes a one-time purchase (no subscription, ever). The first 500 early-access users get v1.0 free forever. Everyone else who used v0.x before launch day gets 50% off — still no subscription. Whatever version you downloaded keeps working indefinitely.
Not right now. Lumitree is Apple Silicon only (M1 and newer). If there's enough interest, we'll add an Intel build.
Lumitree checks for updates on launch via Sparkle. When an update is available, you'll see a prompt and can install with one click. Signed, notarized, and delivered automatically.
Yes. Lumitree stores nothing on our servers. Maps live on your disk. AI API keys are stored in your macOS Keychain, never transmitted to us. The app doesn't include analytics, telemetry, or tracking of any kind.
Use it, break it, and tell us what's wrong. Early access is for finding rough edges — bug reports and feature ideas are worth more to us right now than money. Email hello@lumitree.app with anything you find.
Drop your email and we'll send v1.0 to early supporters when it ships. The first 500 emails get it free forever.
We'll only email you about Lumitree releases. No tracking, no spam, no third parties. Unsubscribe in one click.
