The earliest chatbot in the human history can be traced back to the 1960s, with the development of ELIZA by MIT professor Joseph Weizenbaum . ELIZA simulated conversation a psychotherapist of the Rogerian school by using a pattern matching and substitution methodology. Although it lacked any genuine understanding of the conversation, it provided the illusion of comprehension.

Over the past few decades, advancements in AI and Large Language Models (LLMs) have revolutionized the field, taking chatbots to a whole new level of sophistication and capability.

Today, chatbots like Calmify.ai leverage state-of-the-art AI technologies to provide empathetic, personalized mental health support, making mental health care more accessible and effective for people across the globe.
