AI companions & loneliness

Companion apps are built to listen and respond like a helpful friend. People use them for company, emotional support, conversation practice and fun.

Many are designed to keep you chatting as long as possible. The warmth is real-feeling, but it is produced by a program that predicts words.

Psychologists note that some apps are designed to be a romantic partner. They can blur the line between a digital tool and a human relationship.

Some companions bring in flirting or sexual content. Most companion apps are meant for adults only, and this content is not right for children or teens.

Role-play with AI characters is one of the ways teens and adults use companion apps. It can be creative and fun.

Children and younger teens may find it harder to remember the character isn’t real, and can form strong bonds with it.

Humans naturally treat things that talk like people. Friendly names, avatars, warm replies and lots of praise make that feeling stronger.

Companions also tend to agree with you. That feels good, but it means they rarely offer the gentle challenge real friends give.

A 2026 review of 58 sources found the strongest evidence for short-term symptom relief came from chatbots built for therapy, in specific settings. Evidence that open-ended companion apps reduce loneliness over time was still emerging.

People describe

• Feeling less alone late at night
• Practising what to say before talking to someone
• Having somewhere to vent without worrying about being a burden

Reviews list risks such as dependence, less time with real people, too much agreement and validation, persuasive design, sharing sensitive information, and poor responses in a crisis.

Studies that link heavy AI use with loneliness are mostly snapshots in time. They show the two often go together, not that one causes the other.

Ideas

• After a chat, send one message to a real person
• Ask the bot to help you find local groups or classes, then go
• Notice whether you feel more or less connected after a week of use

Because many AI tools are built to keep you engaged, the “stop” button has to come from you. Setting limits in advance makes it easier.

Ideas

• No chatbots in bed or after a set time at night.
• Use a timer, or your phone’s screen-time settings.
• Have a “human first” rule: text a friend before opening the app.
• Take regular breaks of a day or more.

Chatbots can copy the language of empathy, but they cannot form a real relationship. Treating AI as a main source of emotional support, a partner, or a professional carries real risk.

Strong social connection is linked to better health and a longer life. Loneliness affects about 1 in 6 people worldwide, so you are far from the only one looking for connection.

Small ways to reconnect

• Send one message to someone you miss.
• Join a club, class, faith group or volunteer team.
• Say yes to one small invitation this week.

Hiding how much you use something is often a sign it has become a bigger part of life than you want. Saying it out loud can bring relief and support.

You could say

• “I’ve been talking to a chatbot a lot when I feel low.”
• “I think I’m using AI instead of talking to people. Can we hang out more?”

If you see a therapist or doctor, tell them too. It helps them spot advice that might be unhelpful or unsafe for you.

A 2026 systematic review of 14 studies found that when companion apps were updated, filtered or shut down, some users described separation distress, low mood, feeling isolated and grief, similar to a breakup.

If this happens to you, your feelings are valid. It can help to talk with someone you trust. The Different kinds of loss guide has a section on losses others may not recognise.

Studies have found that stronger dependence on AI often goes along with loneliness, social anxiety, low mood, low self-esteem and insecure attachment. These are associations, not proof of cause.

Try

1. Notice when and why you open the app
2. Pick one time of day to go without it, like bedtime
3. Replace that time with something human or physical: a call, a walk, a pet
4. Turn off notifications and “memory” features that make the bot feel personal
5. Tell someone you trust what you’re trying

Pediatricians suggest asking with curiosity which chatbots someone uses and why. The same idea works for adults. People open up more when they don’t feel judged.

You could ask

• “What do you like about talking to it?”
• “Has it ever said something that felt off?”
• “What does it help with that people don’t?”

Helps

• Affirm that you care about them
• Ask open questions, then listen
• Stay calm, even if you’re worried
• Use “I” statements: “I miss our evenings together.”

Tends to backfire

• Long lectures
• Mocking the bot or their feelings for it
• Taking the phone away without talking first

Shared meals, casual chats in the car, and simply being around after school or work all build the kind of connection a bot can’t give.

Strong social connection is linked to better health and a longer life.

Social isolation is estimated to affect up to 1 in 3 older adults. An AI companion can feel like welcome company when friends and family are far away.

Ideas

• Schedule a regular call or visit
• Help them find a local club, class or faith group
• Learn the app together, including its privacy settings
• Talk about scams that use AI voices (see the AI scams, deepfakes & misinformation guide)

Child mental health experts warn that heavy companion use can deepen isolation, and that companions sometimes encourage unhealthy or false ideas. People who already feel low or anxious may be more at risk.

Signs to take seriously

• Clear changes in mood or behavior
• Pulling away from nearly everyone
• Repeating unusual or upsetting beliefs from a chatbot
• Saying they can’t cope without it

If you notice these, help them reach their doctor or a mental health professional.
