Talkomatic is an online chat system[1] that facilitates real-time text communication among a small group of people. It is distinguished from most online chat facilities in that each participant appears in their own section of the screen, and messages are broadcast letter-by-letter as they are typed. Most chat systems transmit a message only after the sender has indicated that the message is complete.


The original Talkomatic was the world's first multi-user online chat system. It was created by Doug Brown and David R. Woolley in 1973 on the PLATO System[2] at the University of Illinois. It offered six channels, each of which could hold up to five participants.[3] Along with PLATO Notes and a wide variety of games, Talkomatic was one of the features of PLATO that gave rise to a large online community that persisted into the mid 1980s.

Web version[edit]

In 2014, Brown and Woolley released a new version of Talkomatic designed for the world wide web. In its basic functionality it is very similar to the original Talkomatic, but it is based on entirely different technology. Freely available to anyone, it offers an unlimited number of rooms, which can be either public or private. Each room can accommodate up to five people.
