In a TED Talk, the Russian-born entrepreneur Eugenia Kuyda describes the sudden death of her best friend and housemate Roman, the “coolest person” she knew. Grieving and desperately lonely, she immersed herself in his old text messages. At the time, she was working in a conversational AI startup, and she experimented with training a new model using Roman’s text messages. Soon she was texting this model throughout the day, sharing jokes and observations. “It felt strange at times,” she concedes. “But it was also my healing.”

It was this process, according to Kuyda, that led her to create Replika in 2017. Billed as “the AI companion who cares”, Replika is trained individually by each user through a series of questions, resulting in a bespoke chatbot who is “always here to listen and talk” and “always on your side”.
In its first two months of operation, Replika acquired 2 million users; its current chief executive claims its user base now exceeds 40 million. In 2023, a report by the Harvard Business School found 40% of its users were engaged in romantic relationships with their chatbots.
