A letter commits once the same shape reads confidently across consecutive frames, usually well under a second of holding.

Why it feels different
Three promises you can verify from your Wi-Fi indicator.
MediaPipe + TensorFlow.js, running on your machine.
Twenty-one landmarks tracked in your browser tab. No install, no server round-trips, no waiting on a GPU queue.
Your camera stream never leaves the tab.
The camera stays off until you turn it on. Corrections you make stay in your browser as a small calibration you can reset any time.
Practice mode
Learn the alphabet the way you learn a language.
The app names a letter (hard ones or all of them) and watches you form it. Get it right and it moves on. Get it wrong and it tells you what it read instead.
Reverse it
Type a word, watch the hand spell it back.
The other direction is a keyboard-to-handshape walkthrough, useful when you want to check a sign, learn a name, or just play the alphabet back to yourself.
Open the camera
Every letter you sign stays with you.
Point a camera at your hand and start reading.
