Know when someone's behind you.
Peeker watches your back. Literally. A small live preview quietly appears the moment a colleague walks up behind you — so no one ever reads your screen without you knowing again.
Private by default · Nothing saved · For Mac
The problem
Headphones on. Deep work mode.
You don't hear them coming.
Open offices, shared desks, busy corridors. The moment you're most focused is the moment a colleague or manager ends up reading sensitive emails, salary numbers, or personal notes over your shoulder — and you never noticed they were there.
How it works
Three steps. Then forget it exists.
Install in 10 seconds
Drag Peeker into your Applications folder. Grant camera access once. Done — it lives quietly in your menu bar.
Peeker keeps an eye on the room
It quietly watches the space behind your screen. Nothing is saved. Nothing is shared. Nothing leaves your Mac.
A live preview pops up
When someone enters your peripheral, a small webcam window appears in the corner — so you know exactly who’s there before they speak.
Features
Small app. Surprisingly thoughtful.
A quiet window in the corner
A small live view appears exactly when you need it — and disappears the moment they walk away.
Set it your way
Choose the corner, the size, and how sensitive it should be. Peeker fits your habits, not the other way around.
Stays out of your way
Runs quietly in the background. Your Mac stays fast, your battery stays full, your fan stays silent.
Lowers your music
If you like, it gently drops your volume the moment a colleague walks up — so you can actually hear them say hi.
Works with extra screens
Got a second monitor at your desk? Peeker shows up on the screen you're actually looking at.
Invisible in meetings
Automatically hides during Teams, Zoom, and Google Meet calls. Nobody on the call ever sees the corner window.
See it
Quietly working. Always private.
Peeker keeps an eye on the space behind you. The moment someone steps into view, a small window appears in your corner — instantly, without a sound.

FAQ
Questions, answered.
Does Peeker record me or my colleagues?
No. Peeker never saves a single image and never sends anything to the internet. Everything happens on your Mac and is forgotten the moment a person walks away.
Will it work with my second monitor?
Yes. If you have a second screen at your desk, Peeker shows up on the one you're actually looking at — including widescreens and three-display setups.
Will Peeker slow my Mac down?
No. It's designed to stay out of your way. You won't notice it's running, and your Mac won't either — no fan noise, no battery drain.
Which Macs does it work on?
Any Mac running macOS 13 or newer. Older and newer Macs alike — if it can run modern macOS, it can run Peeker.
Will my colleagues see it during a Teams or Zoom call?
No. Peeker automatically hides itself during any meeting or screen-share. The corner window only exists on your screen, never on anyone else's.
What if I change my mind?
Just email hello@peeker.app within 30 days and we'll refund you in full. No forms. No questions. No awkwardness.
Stop getting caught off guard.
Five dollars. Five minutes to install. A lifetime of knowing exactly who's behind you.
