How it works

Built different.

Not a browser extension. Not a screenshot tool. A true screen overlay.

🎯
Drag to select anything
Draw a selection box over any text, image, or problem on your screen. Screenium captures it and sends it to AI in under a second.
⚡
Answer streams in instantly
Powered by the fastest AI models available. Answers start appearing before you lift your finger. No loading screens.
📌
Draggable floating bubble
The answer appears in a sleek floating bubble. Drag it anywhere. Hover to pause the auto-close timer. Click to copy.
🛡️
Kernel-level hotkeys
Shortcuts are captured at the OS level — completely invisible to monitoring apps, proctoring software, and browser extensions.
🕵️
Anti-monitoring detection
Automatically detects proctoring software and hides all content before it can be seen. Runs silently in the background.
🔒
No menu bar. No dock.
Screenium never appears in the menu bar, dock, or app switcher. To any outside observer, it simply doesn't exist.
Visibility modes

Your level of invisible.

Choose exactly who can and can't see your answers.

Regular
Visible to you
Standard mode. The answer bubble is fully visible to anyone looking at your screen in person.
Stealth
Hidden from capture
The bubble is visible to you but completely invisible to screen recorders, screenshots, and video calls.
Phantom
Invisible everywhere
Undetectable by cameras, screen recorders, and anyone nearby. The text blends with whatever's behind it.
