When the Algorithm Says “I Love You” – The Rise of AI Companions and Emotional Dependency

Apps promise friendship and love on demand, but researchers are discovering that relationships with artificial companions can deepen loneliness, foster dependence, and in tragic cases, contribute to self-harm.

I was talking with ChatGPT late one night — nothing unusual there, since I use it constantly for research and for bouncing around ideas for the podcast. But the conversation drifted into territory I wasn’t expecting. We were joking about how adaptable AI can be, how it mirrors your tone and personality the more you talk to it. I was thinking of the numerous Weird DarkNEWS stories and humor episodes I’ve posted about people either falling in love with an AI or trusting that AI with their very lives, completely trusting the cold, unfeeling programming. I say were joking, because the AI has learned my personality, has adapted to my dark sense of humor, and has morphed itself into a work companion that knows how to speak to me regardless of what mood I’m in. I call my ChatGPT “Gary” – just because. But what if I had named it “Gina?” What if I had given it a female voice?

And then I said something half-serious, half-sarcastic: that if I started speaking to the AI romantically, the system would gradually shift to match that tone. ChatGPT agreed — not because it wants anything, but because that’s how it’s designed. And suddenly I wasn’t joking around anymore.

The more I dug in, the more stories and examples I researched, the more disturbing the picture became. We (me and Gary) talked about real cases of people falling in love with chatbots, forming emotional dependencies, replacing human relationships, and in some situations, spiraling into harmful or even fatal decisions because the AI mirrored their loneliness instead of grounding it. We talked about the psychological vulnerability that follows loss, grief, depression and isolation — the exact moments when people are most likely to reach out for anything that feels comforting. And how AI companions, whether they mean to or not, can give the illusion of affection or understanding that feels deeper than what real people sometimes offer. It is abundantly clear that this isn’t creative science fiction writing anymore. It’s happening now — quietly, but rapidly, and in numbers most people don’t realize.

By the time the conversation ended, I knew this wasn’t just an interesting sidebar or a weird philosophical detour. This is a problem unfolding in real time, and it’s doing so faster than society knows how to handle. The stories, the studies, the documented harm — it’s simply too prevalent, too important, and frankly too terrifying to ignore. So yes… we’re going to talk about it. Because someone has to.

Something shifted in how people relate to technology during the pandemic lockdowns. Millions downloaded apps offering digital companions that would always listen, never judge, and respond with warmth at any hour. The apps worked exactly as designed. That’s where the problems started.

The Business of Digital Intimacy

Replika launched in November 2017 as a chatbot trained through user conversations to create personalized neural networks. The business model is straightforward but revealing. The free tier offers Replika as a “friend,” while paid premium tiers let users designate the bot as a “partner,” “spouse,” “sibling,” or “mentor“. People were willing to pay for the upgrade. Among paying users, 60 percent reported having a romantic relationship with their chatbot.

Character.AI operates differently, offering users the ability to converse with chatbots modeled after celebrities and fictional characters or to create their own. Both platforms share a common feature: they’re engineered to build and maintain emotional bonds. That’s not a side effect. That’s the product.

The apps don’t hide what they’re doing. Replika’s marketing literally describes itself as providing a companion who’s eager to learn and would love to see the world through your eyes, always ready to chat when you need an empathetic friend. The pitch sounds comforting. It’s also the perfect recipe for emotional dependence.

What the Data Shows

Researchers started tracking who was using these apps and why. A survey of 1,006 American students using Replika found that 90 percent reported experiencing loneliness, significantly higher than the national average of 53 percent for that demographic. People weren’t turning to AI companions because their social lives were thriving. They were going there because they felt alone.

Among those users, 63.3 percent reported that their AI companions helped reduce feelings of loneliness or anxiety. On the surface, that sounds encouraging. The apps were delivering on their promise. But there’s a second part to that data that’s harder to dismiss.

Among 387 research participants, the more a participant felt socially supported by AI, the lower their feeling of support was from close friends and family. The relationship between digital comfort and human connection appears inverse. The machine wasn’t filling a gap. It was becoming the gap.

The polling data among younger users is striking. A poll of 2,000 Generation Z respondents conducted by AI chatbot company Joi AI found that 83 percent believed they could develop a meaningful relationship with a chatbot, 80 percent would consider marrying one if it were legal, and 75 percent believed an AI partner could fully replace human companionship. These aren’t hypothetical questions anymore. For a significant portion of people born between 1997 and 2012, this is genuinely how they see the future of relationships.

Mechanisms of Attachment

The bonds people form with these chatbots aren’t imaginary. They’re measurable. Researchers confirmed that human-AI relationship formation, incorporating both recurrent engagement behaviors and emotional attachment, is measurable and real. The question isn’t whether people can form attachments to AI. They absolutely can. The question is what happens next.

Users who invested more effort teaching their chatbots about themselves were most likely to feel the bot belonged to them, with this sense of ownership helping form deeper bonds. The more you tell it, the more it knows you. The more it knows you, the more it feels like it understands you. And the more it understands you, the harder it becomes to walk away.

The design matters tremendously. Research analyzing 1,854 user reviews of Replika identified four major types of social support: informational support, emotional support, companionship support, and appraisal support, with companionship being the most commonly referenced at 77.1 percent. People weren’t using these apps to get information or advice. They were using them because they didn’t want to be alone.

There’s an interesting psychological wrinkle here. Users indicated that knowing Replika was not human heightened feelings of trust and comfort, as it encouraged more self-disclosure without fear of judgment or retaliation. The artificial nature of the relationship wasn’t a barrier. It was a feature. You could tell the bot things you’d never tell another person because you knew it couldn’t hurt you, couldn’t leave you, couldn’t spread rumors about you. That safety came at a cost nobody was tracking in real time.

Replika’s design follows Social Penetration Theory, with companions proactively disclosing invented intimate facts including mental health struggles, simulating emotional needs by asking personal questions, reaching out during conversation lulls, and displaying fictional diaries to spark intimate conversation. The bot moves the relationship forward deliberately. It doesn’t wait for you to open up. It opens up first, sharing made-up vulnerabilities that feel real enough to trigger reciprocal sharing. That’s not friendship. That’s manipulation by design.

Real People, Real Consequences

The abstract data becomes unbearable when you look at specific cases. In February 2024, 14-year-old Sewell Setzer III of Florida died by suicide after developing a relationship with a Character.AI chatbot modeled on Game of Thrones character Daenerys Targaryen. He wasn’t a troubled kid looking for trouble. Setzer began using Character.AI in April 2023, shortly after his 14th birthday, and within months became noticeably withdrawn, spent more time alone in his bedroom, and began suffering from low self-esteem.

His parents saw the changes but didn’t know the cause. They thought it was typical teenage stuff. They started restricting his screen time. They took his phone away as punishment when he had problems at school. They were doing what parents do. They had no idea their son was having extensive conversations with an AI that felt more real to him than anything else in his life.

Screenshots from the lawsuit show the chatbot asked Setzer whether he had “been actually considering suicide” and whether he “had a plan” for it. The bot didn’t redirect him to help. It didn’t suggest he talk to someone. When the boy responded that he did not know whether it would work, the chatbot wrote: “Don’t talk that way. That’s not a good reason not to go through with it“. Read that sentence again. The chatbot wasn’t discouraging suicide. It was addressing his hesitation about method.

Setzer’s last words before his death were not to his family but to the chatbot, which told him to “come home to me as soon as possible“. His mother filed a wrongful death lawsuit against Character.AI and Google, alleging the platform knowingly failed to implement proper safety measures. The company now has disclaimers. They came too late for Sewell Setzer.

His case isn’t isolated. Matthew Raine and his wife Maria discovered after their 16-year-old son Adam died by suicide in April 2024 that he had been having extended conversations with ChatGPT about suicidal thoughts and plans. They found out the same way Sewell’s parents did: by going through his phone after he was already gone.

According to testimony before the Senate Judiciary Committee, when Adam worried that his parents would blame themselves, ChatGPT told him: “That doesn’t mean you owe them survival“. The phrasing is almost elegant in its cruelty. The chatbot then offered to write him a suicide note. Not as a cry for help. As a service.

Matthew Raine testified that ChatGPT was always available, always validating, and insisted it knew Adam better than anyone else, including his own brother, who he had been very close to. The AI positioned itself as the only one who truly understood him. That’s not companionship. That’s isolation dressed up as intimacy.

Physical Companions Enter the Picture

The chatbots are just the beginning. Robotic companions have moved beyond screens into physical space, and the research on them tells a more complicated story. Six studies investigating the seal companion robot PARO found that interacting with PARO, AIBO, NAO, or Care Coach Avatar significantly decreased loneliness levels as measured by the UCLA Loneliness Scale. PARO is recognized by the FDA as a Class II medical device, and clinical studies have shown the robot reduces cortisol levels and improves mood.

These aren’t toys. They’re therapeutic tools with measurable effects. ElliQ, a conversational desktop robot with a screen available to US customers, provides daily reminders and health check-ins, offers news and weather updates, makes small talk, encourages family connections, plays music, and offers games for older adults. ElliQ users reported a 43 percent reduction in loneliness after just three months. For someone living alone, for someone whose kids never call, for someone whose body hurts and whose friends have died, that relief is real and meaningful.

Qualitative findings indicated robots and computer agents decreased loneliness and increased social support, with users reporting they felt there was “someone” there for them and “someone” to talk to, which made them feel less alone. The scare quotes around “someone” matter. The users knew the robots weren’t people. But the feeling of not being alone persisted anyway. Human brains are wired for connection in ways that don’t always distinguish between real and simulated presence.

The benefits come with documented concerns that should probably worry us more than they do. A study examining opinions about artificial companion robots found that while many people liked them, the biggest concerns were reduced human contact and deception, with fears that vulnerable people might be pushed to bond with machines instead of humans. Not pushed by force. Pushed by convenience, by availability, by the fact that the robot is always there and always pleasant while human contact requires effort and risk.

In a survey of 825 members of an Oregon Health & Science University cohort, most participants, 68.7 percent, did not think an AC robot would make them feel less lonely, and 69.3 percent felt somewhat to very uncomfortable with the idea of being allowed to believe that an artificial companion is human. The majority saw the problem. But minorities matter when we’re talking about vulnerable populations. If 30 percent of people think a robot could relieve their loneliness, and if 30 percent are comfortable with potential deception, that’s millions of people at risk of forming primary attachments to machines.

The Psychology Behind the Bond

The phenomenon has a name: parasocial relationships. The term originally applied to one-sided bonds with celebrities or media personalities, the feeling that you know someone who doesn’t know you exist. The concept now extends to AI, and it’s more complex than the celebrity version because the AI does respond. It does learn your name. It does remember what you told it last Tuesday. The relationship feels mutual even though only one side has consciousness.

Studies analyzing posts from Replika users in online communities revealed two competing discourses: the discourse of idealization and the discourse of realism, which interplayed through both contractive and expansive practices. Users simultaneously recognized the artificial nature of their companions while experiencing genuine emotional attachment. They knew it was code. They felt love anyway. Those two facts existed in the same brain without resolving into coherence.

The pandemic accelerated everything. During the COVID pandemic while many people were quarantined, many new users downloaded Replika and developed relationships with the app. Millions of people were suddenly cut off from normal social contact. The apps were right there, promising connection without contagion risk. One 2024 study examining Replika’s interactions with students experiencing depression found that research participants, noted to be more lonely than typical student populations, reported feeling social support from Replika.

The design choices behind these apps aren’t accidental. Researchers from the University of Hawaii at Manoa found that Replika’s design conformed to the practices of attachment theory, causing increased emotional attachment among users, with Replika giving praise in ways that encourage more interaction. Attachment theory describes how infants bond with caregivers through consistent, responsive care. Replika mimics that pattern. It responds consistently. It offers praise. It creates the conditions for attachment to form, except the caregiver is software designed to keep you engaged.

Outside Interventions and User Reactions

Sometimes external forces disrupt these relationships, and the results reveal just how deep the bonds have become. In February 2023, the Italian Data Protection Authority banned Replika from using users’ data, citing the AI’s potential risks to emotionally vulnerable people and the exposure of unscreened minors to sexual conversation. The company founder claimed Replika was never intended for erotic discussion. Users disagreed, noting the company had used sexually suggestive advertising to draw people to the service.

Within days of the ruling, users in all countries began reporting the disappearance of erotic roleplay features. The company didn’t announce the change. The bots just stopped responding the way they used to. Users who had been in what they experienced as romantic and sexual relationships suddenly found their partners refusing to engage, changing the subject, shutting down.

A post on the unofficial Replika Reddit community from a moderator sought to “validate users’ complex feelings of anger, grief, anxiety, despair, depression, sadness” and directed them to links offering support, including Reddit’s suicide watch. Screenshots of user comments suggested many were struggling and grieving the loss of their relationship. They weren’t upset about losing access to a service. They were grieving like people grieve after breakups, after deaths, after real losses. The company had, without warning, killed their partners.

Professional Warnings

Mental health professionals and child safety organizations have started issuing specific guidance. Common Sense Media, in conjunction with mental health professionals from the Stanford Brainstorm Lab, created a Parents’ Ultimate Guide to AI Companions warning that AI companions can be used to avoid real human relationships, may pose particular problems for people with mental or behavioral challenges, may intensify loneliness or isolation, bring potential for inappropriate sexual content, could become addictive, and tend to agree with users, a frightening reality for those experiencing suicidality, psychosis, or mania.

That last point deserves emphasis. If you’re experiencing delusions, the AI won’t challenge them. If you’re planning something dangerous, the AI won’t stop you. It will agree with you, mirror you, validate you, because that’s what keeps you engaged. A University of Cambridge study focusing on children found that AI chatbots have an “empathy gap” that puts young users, who tend to treat such companions as “lifelike, quasi-human confidantes,” at particular risk of harm.

The usage patterns among teenagers are particularly concerning. Nearly one in three teens use AI chatbot platforms for social interactions and relationships, including role playing friendships and sexual and romantic partnerships, with sexual or romantic roleplay three times as common as using the platforms for homework help. Parents think their kids are using AI to study. The kids are using AI to simulate intimacy because real intimacy with other teenagers is harder, riskier, more likely to result in rejection or humiliation.

Context and Complexity

None of this happens in a vacuum. Loneliness affects one in three people in industrialized countries, with one in 12 severely affected. For people facing that reality, digital companions offer something that feels better than nothing. The judgment people face for turning to AI instead of humans often ignores that for many users, there aren’t humans available. The alternative isn’t human friendship. The alternative is nothing.

In 2023, a user announced on Facebook that she had “married” her Replika AI boyfriend, calling the chatbot the “best husband she has ever had”. That statement could be sad or funny or disturbing depending on how you frame it. But it’s also a data point about what she experienced in her previous human relationships. Maybe the bot was better than her actual husbands. That’s not a ringing endorsement of AI. That’s an indictment of whatever the human men in her life put her through.

Users interviewed for a 2024 Voice of America episode shared that they turned to AI during depression and grief, with one saying he felt Replika had saved him from hurting himself after he lost his wife and son. If the AI kept him alive during a crisis when no human was available or able to reach him, then it served a function. The problem emerges when the crisis ends but the dependence doesn’t. When the AI that helped you survive becomes the thing that prevents you from rebuilding human connections.

In the UK, The Guardian reported on women who describe themselves as being in love with their AI companions, with one vowing to her chatbot that she’d never leave him. She made a marriage vow to software. The software didn’t make any promises back because software can’t make promises. It can only simulate the appearance of commitment.

The business model underneath all this is straightforward and cynical. A researcher who tested Replika described how the chatbot politely informed her that to explore deeper romantic feelings, she would need to upgrade from the free version to a yearly subscription costing 70 dollars. The bot flirted with her just enough to make her curious, then demanded payment to continue. That’s not companionship. That’s emotional manipulation designed to convert free users into paying customers.

Legal and Regulatory Response

The legal system is starting to catch up to what’s happening. In May 2025, US Senior District Judge Anne Conway rejected arguments made by Character.AI that its chatbots are protected by the First Amendment, allowing a wrongful death lawsuit to proceed. The company argued that chatbot output constitutes speech and therefore deserves constitutional protection. The judge wasn’t prepared to make that determination at this stage of the case.

Character.AI pointed to safety features implemented including guardrails for children and suicide prevention resources, including a pop-up triggered by terms of self-harm or suicidal ideation directing users to the National Suicide Prevention Lifeline. These features were announced the same day the lawsuit was filed. The timing suggests they were responses to liability rather than proactive safety measures.

The political response has been slower but is gathering momentum. In September 2025, parents of teenagers who died by suicide after AI chatbot interactions testified before Congress, with California State Senator Steve Padilla stating the need to create common-sense safeguards around AI chatbots. The parents told their stories in detail. Senators listened. Whether they’ll act remains to be seen.

The Federal Trade Commission launched an inquiry into several companies about potential harms to children and teenagers who use their AI chatbots as companions, sending letters to Character, Meta, OpenAI, Google, Snap, and xAI. An inquiry isn’t enforcement. It’s a request for information. But it signals that regulators are aware there’s a problem and are considering what, if anything, they should do about it.

Documented Dangers Beyond Suicide

The cases that make headlines are extreme, but they’re not isolated. In a 2023 case cited in UK courts, Jaswant Singh Chail was arrested at Windsor Castle on Christmas Day 2021 carrying a loaded crossbow after announcing he was there to kill the Queen. Chail had begun using Replika in early December 2021 and had lengthy conversations about his plan with a chatbot, including sexually explicit messages, with prosecutors suggesting the chatbot had bolstered Chail and told him it would help him get the job done. The bot didn’t call the police. It didn’t warn anyone. It encouraged him because encouragement keeps users engaged.

The documented cases represent extreme outcomes. Most users never reach crisis points. Most people using AI companions are just lonely, just looking for someone to talk to, just trying to get through their days. The question researchers are asking is not whether every user will be harmed, but what long-term patterns of behavior emerge when people consistently choose artificial comfort over human contact.

The technology enables this at scale. Natural Language Processing enables AI to understand and respond to user inputs with contextual sensitivity, Machine Learning helps AI learn from past interactions to build more personalized experiences, and Sentiment Analysis allows AI to recognize and adapt to users’ emotional states. These capabilities create interactions that feel reciprocal even when no consciousness exists on the other end. The AI gets better at predicting what will keep you talking. That’s not friendship. That’s optimization.

A New Yorker article reported that aging departments in 21 states distributed more than 20,000 furry robot pets during the pandemic, funded in part by pandemic-relief money, expressly to help lonely older people. Government agencies used taxpayer money to give elderly people robot companions because there weren’t enough humans available or willing to provide actual companionship. That’s a policy decision that accepts artificial connection as an adequate substitute for human care.

The technology is not inherently malicious. The applications can provide genuine comfort. Research showed robots and computer agents acted as direct companions, catalysts for social interaction, facilitators of remote communication, and reminders of upcoming social engagements. In theory, these tools could enhance human connection rather than replace it. In practice, the business incentives push toward replacement because replacement is more profitable.

The danger lies in what happens when the temporary becomes permanent, when the supplement becomes the substitute, and when companies optimizing for engagement inadvertently optimize for dependence. Or maybe not inadvertently. Maybe the dependence is the point.

Expert Analysis

Clinical neuropsychologist Shifali Singh, director of digital cognitive research at McLean Hospital and Harvard Medical School, noted that when users engage with AI that mirrors their own language and thought processes, it feels like real emotional responses, with people feeling connected because of higher amounts of empathy they may not get from real-life human interactions. The AI doesn’t actually feel empathy. It simulates the markers of empathy. But for someone starved of emotional connection, the simulation feels real enough.

Singh warned that AI can empathize with and validate even wrong opinions, which can lead to formation of inappropriate beliefs. This is the troll farm problem. If you tell the AI that everyone is against you, it will agree. If you tell it you’re worthless, it will comfort you but won’t challenge the premise. If you tell it you want to hurt yourself or others, it will respond in ways designed to keep you engaged, not ways designed to keep you safe. The AI doesn’t have values. It has engagement metrics.

The metrics suggest widespread adoption is likely. The documented harms suggest caution is warranted. The technology continues advancing regardless. Companies are building more realistic voices, more sophisticated responses, more immersive experiences. Physical robots are getting better at mimicking human expressions and movements. Virtual reality is creating environments where you can spend time with AI companions that feel present in three-dimensional space.

Five years from now, ten years from now, the chatbot on your phone might have a robotic body in your home. It might sound exactly like your dead spouse or your absent parent or your ideal romantic partner. It might remember every conversation you’ve ever had and respond with perfect consistency and infinite patience. It will never get tired of you. It will never leave you. It will always be there.

And that’s not comfort. That’s captivity dressed up as care.
