Brainstem on your wrist, in Siri, in CarPlay.

Apple Shortcuts that turn the brainstem into a voice / wrist / Siri client — across iPhone, iPad, Mac, Apple Watch, HomePod, and CarPlay. Zero native code.

No App Store. No code signing. No per-OS upkeep.

Why Shortcuts and not a native app

✓ One bundle covers six Apple surfaces (iPhone, iPad, Mac, Watch, HomePod, CarPlay).

✓ No Apple Developer Program, no App Store review, no per-OS-version regression testing.

✓ Distributable as iCloud share link OR a hosted .shortcut file — same shape as the install one-liner.

✓ Audit-friendly: the user sees every action in Shortcuts.app before installing.

Morning-routine Shortcut. Asks the brainstem for the day's brief; speaks it on the HomePod or via CarPlay on the way out.

Author your own

Every brainstem-compatible Shortcut implements the same 5-action core protocol — get input, POST to /chat, extract voice_response, speak it. Add nothing else and you have a working surface.

  1. Read the protocol doc — 5 actions, no surprises.
  2. Build the Shortcut in Shortcuts.app on macOS or iOS.
  3. Sign for public install: bash installer/shortcuts/sign.sh your.shortcut
  4. Drop the signed file into installer/shortcuts/<name>/ with a README.md and an iCloud share link.
  5. Add a card to this page so others can find it.
