This allows it to mimic human-like conversation, making it a popular tool for entertainment and casual chatting. Developed by Rollo Carpenter, Cleverbot has been online since 1997. It operates by using a vast database of previous conversations, which helps it generate relevant replies. Users can access Cleverbot through its website or various applications, making it easily available for anyone interested in chatting with an AI.
