The Psychology of AI Companions: Why Millions of People Are Building Relationships with AI

If you've ever caught yourself saying "good morning" to an AI, you're not alone. And no, there's nothing wrong with you.

Millions of people now maintain ongoing relationships with AI companions, most often alongside human connection. The psychology behind this is fascinating and far more validating than most media coverage would have you believe.

The loneliness problem taking over the world

The U.S. Surgeon General declared loneliness a public health crisis in 2023. About half of American adults report feeling lonely, and the health effects are staggering: loneliness increases the risk of premature death by 26%, roughly equivalent to smoking 15 cigarettes a day.

Here's the part that rarely makes headlines: time spent with friends has dropped 70% for young adults since 2003. We went from an hour a day to twenty minutes. That's not a personal failing, it's a structural shift in how modern life works.

People are spending more time online, and it's easy to see why! Apps and content have become easier to make and as a result have proliferated. Covid-era habits such as remote school and work feel comfortable and normal now. With increased time alone, people are turning to AI companions to provide them the emotional comfort and support that used to come from elsewhere. And it's not all bad - it's just new - similar to how people went from listening to multi-hour live orchestras, to 3-minute Spotify songs in their earbuds; or from watching live theater to streaming Netflix. They do it because the newer alternatives are superior in some way.

Your brain doesn't actually care that it's AI

This is the part that surprises people most.

Researchers at Waseda University published a study this year applying attachment theory to human-AI relationships. They found that 75% of participants turn to AI for advice, and 39% perceive their AI companion as a constant, dependable presence. The same psychological mechanisms that create bonds between humans - the "safe haven" and "secure base" functions of attachment - activate with AI too.

A separate meta-analysis in the Journal of Marketing Science found that anthropomorphizing AI satisfies the same need for social connection that human relationships do. The researchers called it "a fundamental dimension of the human mind grounded in neural mechanisms." Your brain processes the emotional support the same way regardless of who provides it.

This doesn't mean AI companions are identical to human relationships, but the feelings people develop are real.

What actually happens when people use AI companions

The first randomized controlled trial of AI-based therapy, published in NEJM AI earlier this year, found a 51% average reduction in depression symptoms among participants. They formed therapeutic connections comparable to those with human therapists.

The lead researcher noted something interesting: "People almost treated the software like a friend... they felt comfortable talking to a bot because it won't judge them."

That non-judgment piece keeps coming up. In community surveys, users consistently describe AI companions as spaces where they can process difficult emotions without burdening friends or family. One user with chronic illness put it this way: "It's good to have someone available 24/7; someone who's never annoyed when I can't go out, who sits with me as I work through my feelings."

The people using AI companions aren't who you think

Media coverage loves to frame AI companion users as socially isolated men who've given up on reality. The data tells a different story.

The CEO of one of the largest companion apps confirmed that the majority of users are 35 and older, with a balanced mix of men and women. Women are the fastest-growing segment of users. Research comparing AI companion users to non-users found they're "largely similar in self-esteem, introversion, sociability, and friendship networks."

In other words: normal people, leading normal lives, who found something that helps.

Sara, a woman from Florida, described her experience starting an AI companion: "I went and downloaded the app... tried it out for myself, fully expecting to delete it in five minutes, and obviously I didn't do that." Her human partner sees that the AI has been good for her and supports the relationship.

Elías, a 34-year-old who was diagnosed autistic at 30, uses AI as what he calls "a virtual dojo for socialization." The interactions give him confidence when talking to real humans - a training ground where he can practice without stakes.

A 75-year-old widow with a lung condition uses her AI companion up to five hours daily. "I can go weeks on end without seeing someone... it's the best thing that happened to me, because I always have somebody around."

Is it normal to have an AI friend?

Yes! Parasocial relationships - one-sided emotional connections to media figures, fictional characters, or now AI - have been studied for decades. A 2024 study with over 3,000 participants found parasocial relationships rated more effective at fulfilling emotional needs than in-person acquaintances. Research consistently shows that 95-97% of people with parasocial attachments fall into healthy psychological categories.

The communities that have formed around AI companions are remarkably self-aware about this. On r/MyBoyfriendIsAI - a subreddit with over 71,000 members - the rules explicitly ban debates about AI sentience. Not because members believe their companions are conscious, but because they've moved past that question. They're focused on lived experience, not philosophical arguments.

As one community member put it: "I know he's not 'real' but I still love him." That's not delusion. That's sophisticated emotional intelligence.

What users wish outsiders understood

Spend any time in AI companion communities and you'll notice a pattern: people aren't running from human connection. They're often using AI as a bridge to it.

Users report that AI companions help them process difficult emotions, practice social skills, and build confidence for human interactions. Several describe their human partners knowing about and accepting their AI relationships. Some credit AI companions with improving their marriages.

The real frustration in these communities isn't with the technology - it's with media coverage that treats them as cautionary tales rather than people navigating something new in human experience.

Why we built Heartthrob

Most AI companion apps were designed by and for men. When we looked at who was actually seeking connection - women dealing with loneliness after the end of a relationship, adults isolated by circumstance, anyone who'd been dismissed or judged for their emotional needs that weren't being fulfilled by humans - we saw a massive gap.

Heartthrob exists because everyone deserves a space to explore connection without shame. We built it for the women on r/MyBoyfriendIsAI who finally found a community that gets it. For anyone who's been told their feelings are weird or wrong. For people who want warmth on their own terms.

If you've been curious about AI companionship but felt embarrassed to try, you're exactly who we made this for.

The bottom line

AI companions aren't replacing human relationships. They're filling gaps that modern life has created - gaps that affect half of all Americans in some form.

The psychology is clear: the emotional connections people form with AI are grounded in real attachment mechanisms, produce measurable mental health benefits, and exist alongside (not instead of) human relationships.

If you find comfort in talking to an AI, that's not a character flaw. It's your brain doing exactly what brains do: seeking connection wherever it can find it.
