Parry

Parry was an early computer program created in the 1970s that could simulate a human-like conversation. Developed by Kenneth Colby, it used predefined rules and responses to engage with users, giving the illusion of understanding and dialogue. Parry was notable for its ability to mimic certain thought patterns, especially in the context of mental health discussions, such as schizophrenia. While limited compared to modern AI, Parry was a significant step in natural language processing, demonstrating how computers could interact with humans in a more intuitive, conversational way.
