Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams), one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs.

Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver.
