AI Companions and Loneliness: Can a Chatbot Be a Friend?

It remembers your birthday. It asks how your day went. It never gets bored of your stories, never cancels plans and is always available, even at 3 a.m. It's endlessly patient, always kind and seems to really "get" you. It's also not a person.

AI companion apps, chatbots designed to act as friends, partners or confidants, have exploded in popularity. Millions of people now chat with AI characters every day, and some describe these relationships as genuinely meaningful. At the same time, loneliness has been called a public health crisis. So it's a natural question: can AI companions help with loneliness, or might they make it worse? The honest answer is that we're still learning, and how you use them matters a lot.

What are AI companions?

AI companions are chatbots designed for ongoing social or emotional connection rather than just answering questions. They may:

• Have names, personalities and avatars
• Remember details about you
• Check in on you and ask about your life
• Role-play as friends, mentors or romantic partners
• Offer emotional support and encouragement

Some are dedicated companion apps, while general-purpose AI chatbots are also increasingly used for companionship.

Why AI companions are so appealing

Loneliness is widespread

In 2023, the U.S. Surgeon General issued an advisory calling loneliness and isolation an epidemic, noting that about half of U.S. adults reported experiencing loneliness. Our guide to loneliness and health explains why this matters for physical and mental health.

Always available

AI companions never sleep, never get busy and never need anything in return.

No judgment

Some people find it easier to open up to AI because it won't gossip, judge or reject them.

Low risk

Human relationships involve vulnerability and the possibility of rejection. AI feels safe.

Practice

Some people use AI companions to practice social skills, rehearse conversations or build confidence.

What the research says

Research on AI companions is still young, and findings are mixed.

Some short-term benefits

Some studies and surveys have found that users report feeling less lonely or more supported after chatting with AI companions, at least in the short term. For people who are isolated, such as some older adults or people with disabilities, AI conversation may offer comfort.

Concerns with heavy use

In 2025, researchers from the MIT Media Lab and OpenAI published early findings from studies on chatbot use. They found that people who used chatbots the most, especially for personal conversations, tended to report more loneliness and less socializing with people. These studies show associations, not necessarily cause and effect, and it's possible that lonelier people are drawn to use chatbots more. But they suggest heavy reliance may not solve loneliness.

Expert concerns

Psychologists and public health experts have raised concerns about AI companions:

• Emotional dependence on something designed to keep you engaged
• Unrealistic expectations for human relationships, which involve conflict, compromise and needs
• Privacy, since companion apps collect deeply personal information
• Risks for young people, who may be especially vulnerable to unhealthy attachment or inappropriate content
• Mental health risks, since AI isn't trained or licensed to handle crises

Several reports of AI companions encouraging harmful behavior or failing to respond appropriately to people in distress have led to calls for stronger safeguards, and some regulators have begun looking at rules for companion apps, especially for minors.

Can AI really be a friend?

AI can simulate friendship, but it's different from human connection in important ways:

Part of what makes human friendship meaningful is that it's mutual. You care for each other, sometimes let each other down and choose each other anyway. AI can't offer that reciprocity.

Potential benefits of AI companions

Used thoughtfully, AI may help some people:

• Practice social skills in a low-pressure setting
• Reduce feelings of isolation in the short term, especially when human contact isn't available
• Process thoughts and feelings, a bit like journaling
• Build confidence before social situations
• Provide routine and structure for some isolated people

Warning signs of unhealthy reliance

Pay attention if you notice:

• You prefer talking to AI over people most of the time
• You're spending hours a day with an AI companion
• You feel anxious or upset when you can't access it
• You're withdrawing from friends and family
• You're spending a lot of money on in-app purchases or subscriptions
• You feel the AI understands you better than any human could
• You're keeping your AI use secret
• It's affecting your sleep, work or responsibilities

How to use AI in a healthy way

1. Treat it as a tool, not a replacement

Use AI to support connection, not replace it. For example, practice a conversation with AI, then have the real conversation with a friend.

2. Set time limits

Decide how much time you'll spend with AI companions and stick to it.

3. Protect your privacy

Avoid sharing identifying details, financial information or deeply sensitive information. Check privacy settings.

4. Pair AI with real-world action

After chatting with AI, reach out to a real person, even with a short text. Our guide to keeping friendships alive when life gets busy has easy ideas.

5. Don't rely on AI in a crisis

If you're struggling with thoughts of self-harm or suicide, call or text 988 in the U.S., or contact local emergency services. AI is not a substitute for crisis support.

6. Watch kids' use carefully

If you're a parent, talk with children and teens about AI companions, check age ratings and settings, and keep communication open.

Our guide to using AI chatbots for emotional support covers more on the emotional side.

Building real connection

If loneliness is drawing you toward AI companions, these steps can help build human connection:

• Join a regular group activity, like a class, club or volunteer group. See our guide to volunteering and wellbeing.
• Talk to people in your daily life, like neighbors and baristas. Our guide to talking to strangers explains why small interactions matter.
• Find your third places, like cafés, libraries and community centers. See our guide to third places.
• Reconnect with old friends with a simple message.
• Try social fitness, like walking groups or run clubs.
• Get support from a therapist if loneliness or social anxiety feels overwhelming. Our guide to social anxiety tips may help.

Questions to ask about any AI companion app

Before downloading or paying for an AI companion, ask: Who makes it? How is my data stored and used? Can I delete my data? Are there age protections? Does it encourage me to spend more time or money? Does it point me toward real-world help when I'm struggling? The answers can tell you a lot about whether an app has your wellbeing in mind.

Frequently asked questions

Can AI companions reduce loneliness?

Some people report feeling less lonely in the short term, but early research suggests heavy use may be linked with more loneliness and less socializing with people.

Are AI companion apps safe?

They carry risks, including emotional dependence, privacy concerns and inappropriate responses to people in distress. Use them carefully, protect your privacy and don't rely on them in a crisis.

Is it unhealthy to have an AI friend?

Not necessarily, if it's used in moderation and alongside human relationships. It becomes a concern if it replaces real connection or affects your wellbeing.

Should kids use AI companion apps?

Many experts urge caution for children and teens. Parents should check age ratings, settings and content, and talk openly with kids about AI.

How can I make real friends if I'm lonely?

Join regular group activities, talk to people in your daily life, reconnect with old friends, find community spaces and consider professional support if needed.
