AI Light Board: LED Sign
Your light board for the show
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Ask for any sign you can describe — a name, a heart, a countdown — and it lights up on the dots in seconds. Nineteen writing systems, so the words can be yours.
Hold your phone up at the show and the screen becomes a light board.
Say what you want on it — a name, a heart, a countdown — and the AI writes the sign, then runs it on the dots right away. Not what you pictured? Say what to change.
MADE FOR THE FRONT ROW
Turn the phone sideways and the whole screen is a marquee: big letters, a chase border, hearts that beat in time. The display stays awake for as long as it runs, so you can hold it up for a whole song.
ANY SIGN YOU CAN DESCRIBE
There are no templates to pick from. Ask for scrolling letters, a rainbow wave, a heart that beats, a countdown to the encore — each one is a small display program written for what you asked. If you can say it, it can go on the panel.
YOUR OWN WORDS, IN PIXELS
Chinese, Japanese, Korean, Arabic, Thai, Hindi, Cyrillic, Greek, Hebrew, Vietnamese and colour emoji all render as real dots, using bundled pixel fonts. Put a name on the board in your own writing system.
A REAL MATRIX, NOT A FILTER
The grid is measured to your device — about 52 x 113 dots on an iPhone Pro Max, 72 x 96 on an iPad Pro — and every frame is drawn dot by dot, twenty times a second. What you see is what a panel that size can really show.
THREE ARE WAITING FOR YOU
A light board, a digital clock and a birthday cake with candles are there the first time you open the app. Change any of them by saying what to change.
AND AFTER THE SHOW
A clock on the nightstand. A cake for a friend at midnight. A BACK IN 5 sign for a desk. A quiet aurora to fall asleep to. Everything you keep gets a tile with a live thumbnail, and plays full screen with a tap.
No account. No ads. No tracking. Your boards stay on your device.
