Online chat is like talking to someone using your computer or phone instead of your voice.
You type your messages to the person you want to talk to, and they type back to you. It's like passing notes in class, but over the internet!
You can do online chat with people you know, like friends or family, or with strangers who are interested in the same things as you are.
Online chat can be done on different websites or through apps on your phone. Some chat platforms let you have group conversations with many people at once.
Remember to always be safe when you chat with strangers online, and never give out your personal information to someone you don't know!
