MindStem: Mind Mapping

One field. Save. It lands on your Mac — through your own iCloud. Capture by Siri, the share sheet, or the Action Button too.

MindStem on iPhone is the capture door: one field, one Save.

A thought arrives mid-walk — type it, save it, forget it. It travels through your own iCloud and lands in the Brainstorm tray of the map open in MindStem on your Mac. Thoughts wait visibly until your Mac picks them up, and you can take one back before it goes.

Capture from anywhere: the app, Siri, the share sheet, or a Back Tap / Action Button shortcut ("Capture a Thought").

The maps themselves live in MindStem for Mac — brainstorm against the clock, structure by drag & drop, read your day on the clock, leave as Markdown or PDF. On iPhone, MindStem is deliberately small: capture, not cartography.

No account. No server. No tracking. Your thoughts travel only through your own iCloud.
