Most mind map tools want an account before showing you anything, then keep your maps on their servers. This does neither. Open it and start — no sign-up. Type a topic and AI builds the whole map: branches, sub-branches, structure. Edit by hand from there. Maps sync across iPhone, iPad and Mac through your own iCloud, so they never touch our servers. One purchase covers all three, and it is a native Apple app, not a web wrapper. Free with 8 templates. Pro unlocks the AI.
