A digital privacy screen for macOS that blurs everything except a clear circle around your cursor.
For working in public without turning your screen into a billboard.
Version 1.1 · macOS 13 (Ventura) or later · Apple Silicon & Intel
Peek is a menu bar app that blurs your whole screen except for a clear circle around your cursor. For coffee shops, trains, anywhere with someone next to you.
Three overlay styles: Light Blur, Dark Blur, and Blackout. The clear circle is 100–1200px and follows your cursor with no lag. Clicks pass through to whatever's underneath.
- Open Peek. An eye icon appears in the menu bar.
- Left-click the menu bar icon to toggle the privacy overlay on / off
- Right-click the menu bar icon to access Settings, About, and Quit
- Move your mouse to reveal content through the peek circle

Download Peek v1.1. Open the DMG and drag Peek to your Applications folder.
On first launch, macOS will ask for Accessibility permission (needed for global mouse tracking). Grant it in System Settings → Privacy & Security → Accessibility.
Requires Swift 5.9+ and macOS 13+.
# Build the app and create a DMG
./build-app.shCompiles a release binary, creates Peek.app, packages it into Peek.dmg.
- Over-the-shoulder only. Peek obscures the visual output of your Mac's display. It does not block screen sharing, AirPlay mirroring, Continuity / Sidecar projection, or screen recording. Those paths pull from the framebuffer before the overlay is composited.
Swift + AppKit, zero external dependencies.
