Uthra is like a magic stick that helps people talk and send messages to each other using their computers or phones. It's kind of like having a secret code that only you and your friends can understand. You can use Uthra to send words, pictures, videos, and even sounds to people who are far away from you. It's really cool because you can talk to your whole family and friends at the same time, just like having a big group chat. Just like how you use crayons to make art, you can use Uthra to make connections with people you care about.
