Loneliness has quietly become one of the biggest modern problems, and now AI is stepping in as an unlikely companion. A new study from Aalto University, to be presented at CHI 2026, examines how AI companions impact users over time. And the results are somewhat mixed.
While interacting with AI companions can help users feel supported and less alone, the study also found signs of increasing emotional distress in their online speech over time, suggesting the relationship isn’t as easy as it seems.
Can AI really make people feel less lonely?
According to current studies, yes. Well, at least to a certain extent. Research shows that interacting with AI companions can reduce feelings of loneliness, sometimes leading to short-term effects comparable to human interaction.
The reason is pretty simple. These tools are always available, non-judgmental, and designed to listen. For someone who struggles with isolation, this kind of constant presence can be surprisingly powerful. In fact, many users report feeling “heard” by the AI in a way that helps them open up emotionally.
There is also a practical aspect here. Not everyone has easy access to social support, whether due to geographical location, lifestyle or personal circumstances. AI fills this gap by providing instant, one-to-one interaction at any time of the day.
But is this comfort actually a good thing?
This is where things get complicated. While AI companions can ease loneliness, experts warn they could also change the way people connect with one another, potentially weakening real-world social skills or leading to unhealthy dependency over time. There are also ethical concerns, as replacing human interaction with AI may do more harm than good to vulnerable users.
In a way, this tension defines the space at the moment. AI can comfort and support, but is not a real replacement. After all, being a good listener is not the same as someone who truly understands you.
