How it works

Three steps, ten milliseconds apart.

Peek watches for one thing only: a deliberate turn of your head. Everything else — micro-movements, glancing at a second monitor, leaning back — is filtered out before it reaches Windows.

  1. Your camera finds your face

    Peek reads frames from the webcam you choose and estimates head position and yaw locally, on your CPU, at the frame rate your performance profile allows.

  2. Peek filters intentional movement

    Smoothing removes jitter and drift. Only a turn that crosses your sensitivity threshold — and holds — counts as a deliberate gesture.

  3. Windows switches desktops

    Peek calls the same virtual desktop switch Windows uses for Ctrl Win ←, so animations, pinned windows and desktop names all behave exactly as you expect.

Built for focus

Keep your hands where they are.

A desktop switch is a two-second interruption you make a hundred times a day: reach for a chord, watch the animation, find your place again. Peek removes the reach. You look, the workspace is there, your hands never left the keyboard.

  • No chord to remember
  • Works with any window layout
  • Hotkey still available when you want it
Before Stop typing, press Ctrl Win ←, re-orient.

Private by design

The camera feed never leaves your PC.

Peek is a local process. Frames are read, measured and discarded in memory. There is no account to create, no telemetry pipeline, and no server for your video to be uploaded to — because there is no server at all.

Processed on-device

Face detection and yaw estimation run in the Peek process on your own CPU. Frames are never written to disk.

Nothing recorded

No video, no stills, no landmark logs. Close Peek and nothing about your session persists.

No account, no cloud

No sign-in, no licence server, no analytics SDK. Peek works identically with your network cable unplugged.

Stays inside your machine

Peek requests exactly one Windows capability: camera access. You can revoke it at any time in Settings → Privacy & security → Camera.

Designed for control

Tune it once. Forget it's there.

Every part of the gesture is adjustable: which camera, which hotkey, how far you have to turn, how much smoothing is applied, and how much CPU Peek is allowed to use. Try the controls below.

Activation hotkey

Global hotkey to suspend tracking instantly — for calls, screen shares or focus blocks.

18°

How far you must turn before a switch is triggered. Lower is quicker; higher avoids accidents.

Damps camera noise and micro-movement. Raise it if your desk shakes or the light flickers.

Pick your camera

Multiple webcams, capture cards or a virtual camera — choose the device, and Peek remembers it per machine.

Global hotkey

Bind any combination to pause and resume tracking without opening the window. Useful the moment a camera goes live.

Performance profiles

Efficient for laptops on battery, Balanced for everyday work, Responsive when you want the snappiest gesture.

Quietly available

Lives in the tray. Stays out of the way.

Peek has no taskbar button, no splash screen and no window competing for space. It sits in the notification area with a single icon that tells you whether tracking is on. Right-click for the essentials; that's the whole interface.

  • Starts minimised with Windows
  • Icon reflects tracking state
  • Single-digit MB of memory
