MindMap Chat

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: ask focused questions, generate notes, let AI restructure the map — you review the change before it lands, and undo it in one step — and find ideas later with on-device semantic search.

It's a living visual map rather than a scrolling chat box, so the shape of what you're learning stays in front of you — and nothing is uploaded. The app is useful before you install any model at all: local AI is an upgrade, not a prerequisite. Import your existing Freeplane (.mm) and XMind maps to get started.

Private by design. Your maps stay on your machine, encrypted at rest with two-factor encryption — a password AND a separate key file — so neither one alone can ever unlock your data. Real protection, not just a checkbox.

Your own AI, on your own hardware. By default the LLM runs through Ollama or LM Studio — on your machine or elsewhere on your network — so nothing you write is uploaded and there are no per-token fees or subscriptions. Claude and OpenAI are there if you want a bigger model: strictly opt-in, never on by default, and the app asks before anything leaves your device. Note that a confined snap cannot install or start a local runtime for you: install Ollama or LM Studio on the host and point the app at it.

Released 31 Oct 2026

• Find arXiv papers for any node in your map, get AI answers grounded in them with cited sources, and keep followed topics up to date — in any language.
• Every prompt now has a Resend button that lets you send it again to the chosen model, with an option to undo the replaced reply.
• Links in notes, details, and chat replies are now preserved and open when tapped instead of appearing as plain text.
• Collapsed nodes now show a badge with the number of hidden children; tapping it expands the node.
• Zoom controls, keyboard shortcuts, and a Fit to screen button are now available on the canvas.
• The About section now lists the other platforms the app is available on, with a link to the download page.
• A Features & setup guide is now available from the library menu, the empty library view, and Settings → About.
• A settings read that landed mid-save could return an empty map and wipe all settings; saves now write to a temp file first so readers always see complete data.
• Local model replies no longer run for minutes without stopping; extend and research now have a reply length limit.
• The model-activity overlay no longer gets stuck on screen and blocks interaction after a run is abandoned.
• Switching back to a provider now restores the model you previously selected for it instead of falling back to a default.
• Importing Freeplane and XMind maps now preserves named styles, edge colours, compact layout, and note icon and tag display settings.
• Saving settings no longer crashes if the screen is closed while the save is still in progress.
