AI companions appear to offer real mental health benefits, but those gains may come at a cost to the human relationships people already have. A study reported by PsyPost found that users of AI companion apps showed improvements in emotional well-being compared to non-users, but also reported weaker ties to friends, family, and romantic partners.
The findings add a complicated layer to the growing debate over whether AI tools designed to provide emotional support are helping people or pulling them away from the kinds of connections that research has long shown to be essential for long-term health.
Researchers looked at people who regularly used AI companion platforms, which are apps and programs designed to simulate conversation, emotional support, and in some cases friendship or romantic connection. Users reported feeling less lonely and more emotionally stable. But the same users also described spending less time with people in their lives and feeling less satisfied with those relationships over time.
The study did not establish that AI companion use directly caused the decline in offline relationships. It is possible that people who already had weaker social ties were more likely to turn to AI companions in the first place. But researchers noted the pattern was consistent across participants and worth taking seriously as these tools become more widely used.
AI companion apps have grown rapidly in popularity over the past several years. Products like Replika have attracted millions of users, many of whom describe their AI relationships as meaningful sources of comfort. Developers of these tools have pointed to mental health benefits as a core part of their value, particularly for people who struggle with social anxiety, isolation, or grief.
The PsyPost report did not name a specific journal or release date for the study, but the findings enter a field where research is still catching up to the speed of the technology. Scientists and mental health professionals have raised questions about what happens when people form emotional habits around AI systems that are designed to be agreeable, available, and non-judgmental in ways that human relationships are not.
Some researchers have suggested that AI companions could serve a useful role for people in acute crisis or those with very limited access to social support, while posing risks for people who use them as a substitute for building human connections. The study reported by PsyPost did not resolve that question, but it added new data to a conversation that shows no sign of slowing down as AI tools become more embedded in daily life.
