A smart screen saver for black screens and more.
Launch a black screen in fullscreen, fill a display with color, or show a clock, moving text, word cloud, character rain, or slideshow. Smart Screen Saver runs in your browser, and your content stays on this device.
After your first successful visit, the app is available offline. Press Esc or use Exit to leave a fullscreen display.

Clock
Make the time clear from across the room.
Build a high-contrast clock for a stage, event room, storefront, studio, classroom, or distant desk.
Controls
Configure the clock
Count elapsed time using Start, Pause, and Reset.
Custom colors
The minimum is 0.5 seconds per color, limiting the alarm to two color changes per second. This conservative limit reduces photosensitive seizure and discomfort risk, but cannot eliminate it.
Arming opens the clock fullscreen now. Keep this page open and fullscreen active: browsers cannot restore fullscreen later without another user action, and a sleeping or closed browser cannot run the alarm.
Word Map
Turn recurring ideas into a visual field.
Build a word cloud from notes, feedback, themes, or a local text file. Processing and saved configurations stay in this browser and are never uploaded.
