A mind map that thinks with you

Turn what you're learning into a visual knowledge map where every node is an AI you can talk to — running against a local model, working offline, with everything stored encrypted on your own machine.

Download — it's free Will it run on my machine?

A living visual map instead of a scrolling chat box — the shape of what you're learning stays in front of you, and nothing is uploaded.

Ask about one idea, not the whole document

Open a chat on any node and the AI sees that branch — its notes, its children, its parent — and nothing else. No 400-message transcript to scroll, no context you did not ask for.

The AI edits the map, and you can take it back

Ask it to extend a branch and it rewrites the structure — as a single reviewable change. One undo puts everything back exactly as it was.

Find things by meaning, with the network off

Semantic search runs entirely on-device against an embedding model that ships inside the app. It finds the node you meant, not the word you typed — on a plane, in a tunnel, anywhere.

Why not just use a chatbot?

Because a scrolling transcript loses the shape of what you're learning. Here the structure is the interface:

• AI scoped to a single idea. Ask about one concept without dragging in the rest of the map.
• Notes stay where they belong. An explanation is pinned to the exact node it explains, not buried 400 messages up.
• AI can restructure the map — and you review the change before it lands, then undo it in one step if you don't like it.
• Find things by meaning. Semantic search runs on-device, so it works with no network at all.
• Bring your existing material. Imports Freeplane (.mm) and XMind files.

Will it run on my machine?

Almost certainly — and here's the part most AI apps won't tell you plainly: the app is useful before you install any model at all. Local AI is an upgrade, not a prerequisite.

Minimum system versions

Older systems aren't supported: on macOS below 14 the app will refuse to open, and on Linux the packages will fail to install against an older glibc.

Supported local models

Pick your runtime: Ollama or LM Studio. On desktop the app installs and starts Ollama for you on Windows, macOS and Linux, and fetches the model you pick — there's no command line to fight. It does the same for LM Studio on Windows and macOS; on Linux LM Studio ships only as an AppImage, so that one is a short manual setup. On Android neither runtime runs on the phone, so the app simply connects to a server on your network — nothing is downloaded on-device. Prefer to set it up by hand, or share one server across your whole network? There are guides for both. These are the models it ships support for:

Memory figures are approximate and assume the default quantised weights; a GPU is a nice-to-have, not a requirement. The app runs against Ollama or LM Studio — on your own machine or elsewhere on your network — and this list is a starting point, not a cage: any model your runtime serves works. The cloud rows need nothing from your machine: Claude and OpenAI run on their own servers, are opt-in, and are billed by them.

Download

Free, no account, no sign-up. Version 1.19.0, released 14 September 2026.

Also on Snap, Flathub, Chocolatey, winget, Scoop, Homebrew and AUR.

macOS note: the download is a universal build containing both Apple Silicon (arm64) and Intel (x86_64) code, so it runs natively on either. The Apple Silicon side is newly added and has not yet been tested on real Apple Silicon hardware — if the app misbehaves on an M-series Mac, you can fall back to the Intel build inside the same download: install Rosetta 2 with softwareupdate --install-rosetta, then right-click the app in Applications, choose Get Info, and tick Open using Rosetta. Reports either way are welcome.

Snap note: the Snap is sandboxed, so on some Linux systems it can't reach your host's GPU drivers (notably certain NVIDIA setups) and the window opens black. If that happens, install the .deb package above instead — it runs unsandboxed and uses your system's own GPU drivers, like any native app. This is a display-only limitation: local AI is unaffected either way, because the runtime runs as a separate service outside the app and keeps full GPU access regardless of how the app is packaged.

What "private" actually means here

Not a slogan — the specifics:

• No account. There is no sign-up, because there is no server to sign up to.
• Encrypted at rest. The database and settings are AES-256 encrypted (SQLCipher) with your passphrase — safe to keep in Dropbox, Drive, or any storage you don't fully trust.
• Your files, your folder. Maps and notes live in a directory you choose and can back up or delete yourself.
• Works offline. Semantic search is fully on-device. With a local model pulled, so is the AI.
• Nothing leaves your machine, by default. The AI runs against Ollama or LM Studio on your own computer or local network. Claude and OpenAI are available if you want them, and they are strictly opt-in — never selected for you, and the app asks before a single word is sent.
• No AI bills, by default. Run the LLM on your own hardware and there are no per-token fees or subscriptions. Choose a cloud provider and you pay them directly — the app takes no commission and never sees your account.

Common questions

Is it really free?

Yes. No paid tier, no trial, no account.

Is it open source?

No — it's free to use but not open source, licensed under the Elastic License 2.0 (which mainly means nobody may resell it as a hosted service). The source isn't published today. You can read the licence in full.

Does it phone home?

It checks for updates on startup, which you can switch off in Settings. That's the only outbound request the app makes on its own. Everything else — your maps, notes and chats — stays on your own machine or network; the AI talks only to your own Ollama or LM Studio server. See the privacy page.

Can I use it with an existing mind map?

Yes — import your Freeplane .mm or XMind files and carry on from there.
