About this app

This application aims to honor the work of Joseph Weizenbaum, who created the first chatbot, ELIZA, in the 1960s at MIT, and significantly contributed to the discipline of Artificial Intelligence.

ELIZA was designed to mimic a Rogerian psychotherapist, and although it is based on a fairly short and simple script, it performed remarkably well and provided valuable insights into the nature of human-computer conversational interfaces. To recognize Weizenbaum's work, I thought that ELIZA deserves a place here, alongside other applications.

This application functions offline and maintains user privacy by not collecting any data. It's based on the original 'ELIZA' script, as published in Weizenbaum's 1966 paper "ELIZA - A Computer Program For the Study of Natural Language Communication Between Man and Machine".

Really bad. Doesn't answer any questions. Very closed conversations. Ask it something and it will say "what do you think" or "why do you ask that"

it is very bad because when i said i don't have any problem he said why don't you have any? it should be a problem discussioner where you can discuss your problems it is not good 😡i don't think it deserves to be a chatbot 🤬🤬
