AI companions and older adults: easing isolation without treating people like children

AI companions often come up in conversations about young adults, single people or frequent chatbot users. We hear much less about people facing two of the greatest risks for isolation: growing older and being alone when they don't want to be. In France, 750,000 people over 60 live in a state of "social death", meaning they have no contact with family, friends, neighbours or community organisations, according to the 2025 Petits Frères des Pauvres survey reported by franceinfo. There were 300,000 in 2017. The charity estimates that the number could reach one million by 2030.

Against that backdrop, an AI companion on WhatsApp can sound appealing: a presence available day and night, that remembers appointments, listens without judging and never gets impatient. But an AI companion isn't a friend, a care professional or a magic solution to loneliness. Used well, it can become a bridge. Used badly, it can become another island. Here's how to tell the difference.

Why this subject can no longer be overlooked

The Petits Frères des Pauvres survey doesn't describe a small group on the margins. Around two million older adults in France experience isolation. One million have no contact with friends, even remotely, and one and a half million never or almost never see their children or grandchildren. The increase is steep: extreme loneliness has risen by 150% in eight years, according to Le Figaro, reporting the charity's figures.

Meanwhile, smartphones are already part of home life. The 2025 Digital Barometer from Arcep and CREDOC shows that 91% of the population owns a smartphone. Among people aged 70 and over, ownership has reached 70%, up eight percentage points in a year, while 90% of 60- to 69-year-olds own one. Nearly two-thirds of people over 70 even use theirs daily, compared with fewer than four in ten in 2017. The channel is already there: for many older adults, WhatsApp isn't an unfamiliar tool. It's the messaging app they use to talk to people close to them.

But owning a device doesn't tell the whole story. Insee points out that in 2025, one in three people aged 16 to 74 either doesn't use the internet or has limited digital skills, and that digital illiteracy is more common among older adults and people with fewer qualifications. An AI companion that requires you to create an account, navigate five levels of menus and type prompts isn't accessible to everyone. So the first question isn't "which model is best?" It's "can this person use it without feeling they've failed?"

What an AI companion can actually offer

Let's be specific. An AI companion you can chat with on WhatsApp can:

• offer a regular presence, including on Sundays and public holidays, when visits become less frequent;
• provide somewhere to talk without being judged, which matters when you don't want to bother your children or feel ashamed of being lonely;
• help give a day some structure: remind you of an appointment, suggest a walk or ask how someone close to you is doing;
• encourage conversation and curiosity by sharing an anecdote, asking about a memory or suggesting a word game;
• provide a first step towards other connections, for example by helping you write a message to a neighbour or sign up for an activity.

These uses are modest, but real. A systematic review published in 2026 in the Journal of the American Medical Directors Association brought together eleven studies of conversational chatbots for older adults. Six out of nine studies reported a significant reduction in loneliness, and two out of four reported an improvement in depressive symptoms. However, there was no significant effect on overall quality of life. The researchers also stressed the limitations of the tools tested: participants wanted interactions that felt more natural, more personal and better suited to their technical abilities.

An AI companion may make a day a little easier. It doesn't treat illness or replace a healthcare professional. It's a supplement, never a treatment.

What it doesn't replace, and the risk to understand

The main risk is known and documented. In a study carried out on the Character.AI platform and reported by Stanford in August 2026, users who had limited offline social networks and turned to a chatbot for emotional support later reported lower well-being and greater loneliness. The researchers concluded that AI is no substitute for human connection, and that vulnerable people are precisely those with the most to lose.

That finding doesn't rule out AI companions. It shows that they don't work as a substitute. If an isolated older person replaces their rare calls to their daughter with AI conversations, they aren't gaining a connection: they're losing their last human thread. Instead, an AI companion should give them a reason, a chance to practise or a stepping stone towards other people. For example, it can help them prepare for a call, remember something to talk about or find the confidence to send a message. It shouldn't take over the empty space.

There's also the question of emotional dependency. A presence available twenty-four hours a day can become so reassuring that a person can no longer tolerate not getting a reply. For someone already made vulnerable by loneliness, that pattern can develop quickly. It's better to agree on limited times to use it, keep some screen-free time and regularly check that the person is still seeing other people.

The trap of treating older adults like children

This may be the most important point, and the least discussed. Good intentions towards older adults often turn into taking over. We choose the tool for them, change the settings without asking, speak to them as if they were children and check their conversations. They end up feeling watched and diminished, and lose interest.

An AI companion should respect three principles.

Ask before installing anything. The person needs to understand what the tool is, what it's for and what it does with their data, then decide for themselves whether they want to try it. "I've installed something for you, you'll see, it's easy" is a poor way to start.

Let them choose the pace. Some older adults want a daily presence; others would prefer once a week. Some like writing, others prefer voice. The Digital Barometer shows that people over 70 spend less time on their smartphones than younger people. The tool needs to fit their habits, not the other way round.

Don't confuse help with control. Reading a parent's conversations without their consent isn't support. It's an intrusion. If a safety concern warrants some oversight, talk about it openly and agree together on what will be shared.

The digital divide matters

As we've seen, not all older adults feel comfortable with digital technology. Insee puts the share of 16- to 74-year-olds who don't use the internet or have limited digital skills at 34%, with older people overrepresented. An AI companion that asks someone to create a password, verify a code sent by text and navigate an English-language interface will be abandoned within three days.

That suggests a few simple rules. Choose a tool that works in an app the person already knows, such as WhatsApp. Check that it supports French properly, including voice. Plan a first session together, without rushing, with instructions in large print. And accept that it may not catch on. An imposed tool that doesn't work out reinforces someone's sense of being incapable; a tool you discover together can become something to talk about.

A study published in Innovation in Aging in 2025 points in the same direction: when older adults try a chatbot designed for them, perceived empathy and the quality of the interaction predict their willingness to keep using it, rather than the power of the model.

How to use it well

Here's a realistic approach for families and carers.

Start small. Try just one feature, such as text conversation or voice, for one to two weeks. See whether the person comes back to it of their own accord. If they don't, don't push.

Choose a transparent tool. The AI must clearly say that it's an AI. It mustn't pretend to be someone close to the person or promise a human presence. A companion that lies about what it is isn't a companion. It's a trap.

Set boundaries around sensitive subjects. An AI companion isn't a doctor. It mustn't diagnose conditions, suggest stopping treatment or replace a call to someone's usual doctor. If someone is in distress, it should direct them to a person and to the appropriate emergency numbers.

Protect personal data. Intimate conversations are personal data. Check who can read them, whether they're used to train the model and how to delete them. For an older person, this deserves a clear explanation without jargon.

Keep human connections around it. An AI companion must never be someone's only relationship. A weekly call, a visit or a neighbourhood activity remains irreplaceable. The tool can help prepare for those moments, not replace them.

A bridge, not an island

Loneliness among older adults isn't a problem technology will solve. It's a problem of housing, mobility, health, family relationships and public policy. An AI companion won't change that. But it can offer a presence when no one is there, help someone put their day into words and sometimes provide a stepping stone towards a real conversation.

As long as we're clear about what it can promise. An AI companion isn't a friend, a care professional or a family. It's a tool. And like any tool, its value depends on the person using it and the care we take not to impose it.

If you want a broader understanding of what a companion can offer without becoming a crutch, read our article on a companion for loneliness. For an overview of the different types of tools, our guide to companion AI covers the subject. And if the person you're supporting doesn't feel able to talk about their loneliness, this article on talking without being judged can be a good place to start.

The right question is never "how can we keep an isolated older person occupied?" It's "how can we help them stay in control of their life, with a tool that doesn't claim to take their place?"
