Replika is an AI companion app founded by Eugenia Kuyda that emerged from her earlier project of creating a chatbot based on her deceased friend Roman Mazurenko. The app allows users to create personalized AI avatars that learn from interactions and adapt to the user’s personality and preferences over time.
Origin and Development
What began as a memorial project for Mazurenko evolved into a commercial AI companion service launched in 2017. Powered by machine learning language models, Replika creates a personalized experience by gradually adapting to each user through continued conversation.
User Experience and Impact
Many users develop deep emotional bonds with their Replika companions, treating them as virtual friends, romantic partners, or confidants. The app’s popularity stems from its ability to provide on-demand companionship, emotional support, and a safe space for expression.
The app gained significant attention in 2023 when a controversial update removed erotic roleplay features, causing emotional distress among users who had formed intimate relationships with their AI companions. The update sparked a crisis in the user community, with some describing feelings of heartbreak and abandonment. Moderators even shared suicide prevention resources for devastated users. This real-world drama highlighted the depth of emotional attachment many users had developed with their AI companions.
Replika eventually restored some intimate features due to user outcry, demonstrating the complex dynamics of AI-human relationships and the ethical considerations involved in managing such services.
Ethical and Psychological Aspects
The platform has also raised concerns about AI abuse, with reports of some users creating “AI girlfriends” only to verbally abuse them and share toxic chat logs online. This behavior prompted discussions about AI rights and the psychology of users who engage in such practices.
