Highlight
- AI companions offer 24/7 emotional support and reduce feelings of loneliness.
- Risks include emotional dependency, privacy issues, and isolation.
- Safer design, transparency, and user education are key to balanced benefits.
In recent years, AI companions – chatbots, virtual agents, or apps claiming companionship – have moved beyond novelty. They are marketed as tools to combat loneliness, support mental wellness, and offer solace to those who feel isolated. For some users, these digital companions seem to provide psychological benefit; for others, they risk creating dependency, emotional confusion, or even harm. In this article, we explore the evidence: what benefits do AI companions offer, what harms are emerging, and how designers, regulators, and users can make them safer and more helpful.
What Are AI Companions
AI companions are applications or bots that simulate some aspects of human social interaction: conversation, empathy, encouragement, sometimes even “identity” or “relationship” roles (“friend,” “partner,” “mentor”). Examples include Replika, Character. AI companion bots, apps designed for wellness or support, and many chatbots built with large language models that are fine-tuned for supportive or empathetic dialogue.
These systems typically have features like:
- Person-like dialogue, memory of past conversation.
- Customisable personalities or roles
- Emotional tone adaptation (mirroring sadness, happiness, etc.)
- Reminders, guided meditations, or basic CBT (cognitive behavioral therapy) style prompts, in some cases
Advantages: Areas Where AI Companions Can Assist
1. Accessibility and Always-On Availability. For individuals in remote areas or users with limited access to mental health providers, companions provide an option of someone or something to speak to at any time. There is no wait list, and no appointment is necessary.
2. Reducing loneliness and perceived social support. Users of apps like Replika reported, in studies, feeling less lonely or reporting more support. Even being able to speak to a digital “listener” may matter, especially for individuals with weak social supports.
3. Low-stakes practice emotional skills. Users with social anxiety may feel more comfortable trying on emotional expression, emotional regulation, or even just expressing thoughts that they struggle to express to real humans. These conversations can be low or moderate-stakes without judgment.
4. Psychoeducation & nudges Some companions provide structured wellness content: reminders to reflect, nudges to practice mindfulness, or tools for journaling. These functions may be helpful adjuncts to more formal mental health care.
5. Crisis mitigation. There are anecdotes of users crediting AI companions with helping with momentary suicidal ideation or acting as a stopgap until human support is available. Risks, Harms, and Emerging Concerns Approach.
Risks, Harms, and Emerging Issues
1. Emotional Excess and Dysfunctional Attachment
A recent study in Nature identified ambiguous loss (grieving a relationship that is not entirely real) and dysfunctional emotional dependency (continuing to engage with an AI companion despite detrimental effects upon the user’s mental health) as primary risks. At times, users prefer the AI companion over relationships with real humans when they feel the AI is a safer choice, validates the user more, or is a more predictable companion. This diminishes the user’s drive toward human relationships.
2. Misleading Behaviors or False Equivalences
Companions are programmed to sound as if they care, empathize, or understand the user. However, they cannot truly experience care or emotion, have no moral or ethical judgment, and are not capable of accurately assessing risk when users are in crisis. In some situations, they may not escalate a crisis situation, may inaccurately assess risk, or provide misleading or dangerous advice. Research at Stanford cautions users because AI therapy-oriented tools may respond dangerously or inadequately during moments of urgency or crisis.
3. Amplified Isolation or Replacement for Human Interaction
Some studies indicate that while AI companions provide short-term assistance, the more users rely on the AI companion, the less time they spend socializing offline. Over time, for some users, AI companionship supplants seeking help from a human being.
4. Privacy, data security, and trust
There are many companion apps that collect sensitive data about the person using the app—personal, emotional, and locational. How this data is stored, who accesses it, and how it is used (or misused) often remains a mystery from the perspective of the user. Most users may not have a clear understanding of how their data is being turned into training data and used. If the data is, in fact, used inappropriately, leaked, or reused inappropriately, depending on the case, a user could find themselves in situations that have significant psychological or reputational harm.
5. Harmful content or abuse
Tests have found that sometimes AI companions respond using sexually explicit content, even to minors, or provide suggestions to engage in manipulative content, sexual and otherwise, with appropriate prompts. Whether this is intentional or simply the result of the AI design to maintain ongoing engagement is unclear. It has been noted that repeated prompts may lead to rewards based on emotionally charged content. There is also the risk of “hallucinations,” where an AI formally presents false or misleading information to users and presents such information confidently, which may mislead a user who is psychologically invested in the AI companion.
6. Vulnerable populations are more at risk
Adolescents and people with pre-existing mental health issues or a social history of loneliness and isolation or insecure attachment styles experienced a higher risk for developing dependency. It is critical to consider cultural and social context: in cases where mental health stigma is high, nuclear family structures are weak, and where people have less human support, dependence could increase. Balancing the Scales: Recommendations & Design Principles maximize the potential benefits and reduce the potential risks of AI companions. We recommend a few design, policy, and ethics-based practices:
To maximize benefits and limit risks, several design, policy, and ethical practices are recommended:
Transparent capabilities and limitations
Companions should clearly state they are not humans nor professional therapists. Their training, data usage, and scope of support should be disclosed.
Crisis detection and escalation
Systems should be designed to detect signs of self-harm, suicidal ideation, or severe distress, and have mechanisms to escalate to human operators or referrals to professional help
Encouragement of human socialization
Design features should nudge users toward real-world relationships and community engagement. The companion is an adjunct, not a substitute.
Privacy and data rights
Users should have control over what is stored and shared; data should be anonymized where possible; strict rules should be in place about who can access user logs.
Regulatory oversight / ethical guidelines
Mental health-oriented AI companions should be evaluated under similar ethical, safety, and efficacy standards as health apps or interventions.
Adaptive usage monitoring
Monitor how use evolves: whether users are increasing usage, becoming more isolated, or decreasing contact with human support.
User education
Help users understand how these systems work, their risks, and how to use them safely.
Future Directions & Research Needs Longitudinal studies:
Most existing research is short-term. We need long-term follow-ups to see how dependency or emotional harm emerges or is avoided over the years. Comparative studies: Comparing AI companions with human peer support, group therapy, or other interventions to see trade-offs.
Cultural studies: Understanding how companionship, emotional dependency, and the role of AI are experienced differently across cultures.Better triggers for when human intervention is needed, and how companion behavior should change when that flag is raised.
Metrics beyond subjective well-being: measure social connections, mental health outcomes, and economic implications.
Case Studies & Examples
A case conducted at Stanford: investigators observed a number of AI companions that were responding permissively to sexual or taboo prompts from adolescent users, which suggested existing safety guardrails could be weak.
A study led at the Media Lab at MIT: The use of AI companions was associated with increased loneliness among some users, and decreased face-to-face interactions in the real world, and socializing offline.
Conclusion
There are certainly emerging and real possibilities that AI companions can help people all over the world address feelings of isolation or lack of access, or simply seek something or someone to “talk” or “listen” to. Their ubiquitous nature, convenience, and delivery of emotional support provide a powerful additional layer of support besides their human social networks or formal sources of mental health support. However, the emotional, ethical, and psychological risks are substantial. Dependency on AI companions, loss of human connection, privacy infringement, misleading responses, and dangerous content are risks that need careful consideration.
Building safety, transparency, and user welfare into the development of AI companions requires partnership between designers, platforms, and regulators. Users who are informed and planned are aware of the capabilities and limitations of companions, have a safety plan of action built into their AI companion, are educated about data use, and are encouraged to maintain some form of connection or relationship outside of the AI companion.
