Your camera notices where you turn
Apple's Vision framework reads which way your head is turned — in memory, on your Mac. A quick calibration teaches it where your screens are.
For Macs with two or more screens
Look. Type.
Turn to a screen and your keyboard follows. KeyFollow moves focus to where you're looking — no clicking, no typing into the wrong window.

Monitor
You're typing on the big screen. Focus is right where you are.
Typing → MonitorSet up intwo minutes
Download, allow the camera and Accessibility, follow a dot for a few seconds per screen. That's it.
See.Decide.Type.
It only acts when you mean it
Quick glances are ignored. Nothing moves while you type or use the mouse, or when you look at your phone.
The right window is ready
The window you last used on that screen comes forward and the pointer comes along. Just keep typing.
Calm by design
A focus switcher that jumps around is worse than none. KeyFollow is tuned to stay out of your way.
Adapts as you move
Lean back, sit closer, move a monitor — your clicks keep teaching it where you look.
No clicks, no side effects
Focus moves through macOS itself, so your text cursor and split panes stay exactly where they were.
Waits while you type
Glance at notes on the other screen mid-sentence — focus stays put until you stop typing.
Works with your setup
Side by side, stacked, a laptop beside a monitor — even with the camera off to one side.
Ignores the room
Looking at your phone, the desk or someone walking past doesn't move anything.
Pause any time
⌃⌥⌘G pauses and resumes. The camera stops by itself when your Mac locks or sleeps.

Questions
Is it tracking my eyes?
Mostly your head. Which way your head is turned is what tells your screens apart, and that works reliably with an ordinary webcam — even the built-in camera of a laptop placed to the side.
Do I need two displays?
Yes. KeyFollow switches between displays, so it needs at least two. With one display it simply waits.
Which camera does it use?
The built-in camera by default. You can pick any connected camera — including an iPhone via Continuity Camera — in Settings.
What if I move my monitors?
KeyFollow keeps learning from where you click, so everyday changes are absorbed automatically. After a big change it suggests a one-minute recalibration.
Why is the camera light on?
macOS always shows the camera light while any app uses the camera. Pause KeyFollow from the menu bar or with ⌃⌥⌘G whenever you like; it also stops by itself when your Mac locks or sleeps.
What permissions does it need?
Camera, to see which way you face, and Accessibility, to bring the right window forward. KeyFollow never reads window contents or records your screen.
Can I try it before buying?
Yes — every feature is free for 7 days, so you can make sure KeyFollow works with your camera and screens. Because of the trial, all sales are final. See the terms.
