Pair your iPhone with your Mac, and control Codex, Claude, and Cursor with a press, a turn, or your voice — hands off the keyboard, eyes still on your work.
CTRL Micro Host
Connected
Your iPhone becomes the remote. Your Mac stays where it is.
01
Open CTRL Micro on your iPhone, enter the code shown on your Mac, and the two stay connected on your network.
02
Six keys, a dial, a joystick, and your voice — mapped to the actions you use most, right from your hand.
03
Whichever AI tool is running on your Mac reacts in real time, exactly as if you'd reached for the keyboard.
Codex
Jump straight to any task, start a new one, or dictate — without leaving what you're doing.
Claude
See what's running, start a voice chat, and approve actions from across the room.
Cursor
Switch tasks and approve or decline its next move with a single press.
Your Mac
The same keys double as shortcuts for the apps, volume, and Siri you already reach for.
Codex, Claude, and Cursor today — built as a protocol, so it doesn't have to stop there.

CTRL Micro Host 1.0.0 is available for Mac. The iPhone companion is currently available to invited TestFlight testers; its public App Store listing remains in preparation.
When OpenAI's Codex Micro sold out, we built the same tactile control experience in software — six keys, a dial, and a joystick, on the iPhone you already carry.
Codex Micro is a product of OpenAI and Work Louder. CTRL Micro is an independent project, not affiliated with or endorsed by either — see the original.
