A native macOS mind-mapping app with hand-drawn branches, five layouts, and optional AI that turns a prompt into a structured map in seconds. Your files, your disk, one-time purchase.
A focused set of tools, all keyboard-first, all native.
Type a topic, pick a shape — brainstorm, plan, compare, study, SWOT — and get a structured map in seconds. Expand any branch with one click. Chat with your map to refine it.
Tapered organic edges that thicken toward the root, like real tree branches. Bend any curve. Reroute endpoints. Your map looks like thinking, not a flowchart.
Radial, horizontal tree, vertical tree, left/right balanced, org chart. Switch with the command palette — your structure is preserved, only the geometry changes.
Hold Shift and drag from one topic to another to draw a relationship — dashed, labelled, separate from the parent-child tree. Because real ideas are graphs, not just trees.
Hit ⇧⌘P to enter presentation mode. Step through your map one branch at a time, with smooth zoom transitions. Pitch directly from the canvas — no slides to build.
Tab to add a child, Return for a sibling, Space to edit, ⌘K for the command palette, ⌘Z for anything. Arrow keys move spatially. Your hands stay on the keys.
Use Apple Intelligence for free, or plug in OpenAI or Claude with your own API key. You pay the model provider directly — nothing goes through us.
Maps save as plain files on your Mac. Auto-save, full undo, import from OPML / Markdown / FreeMind, export to PNG, PDF, SVG, OPML, Markdown. No accounts, no lock-in.
Under 3 MB. Written in Swift and SwiftUI. Launches instantly, runs cool, feels like a Mac app because it is one. Apple Silicon native.
No account. No card. No trial timer. Just download and use it.
No. On macOS with Apple Intelligence, generation is free and on-device. If you want OpenAI or Claude, you plug in your own key — Lumitree calls them directly from your Mac. We don't proxy anything.
Wherever you save them — the same way TextEdit or Pages saves a document. Plain files on your disk. No account, no cloud, no sync service.
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 as a thank-you. Everyone else who used v0.x before launch day gets v1.0 at half price — still no subscription. Whatever version you downloaded keeps working on your Mac indefinitely, regardless.
Not right now. Lumitree is Apple Silicon only (M1 and newer). If there's enough interest, we'll revisit.
Lumitree checks for updates on launch and installs them in-place when you approve. Signed, notarized, and delivered via Sparkle.
Use it, break it, and tell us what's wrong. Early access is for finding the rough edges — bug reports and feature ideas from real users 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.
