Men who have virtual “wives” and neurodiverse people using chatbots to help them navigate relationships are among a growing range of ways in which artificial intelligence is transforming human connection and intimacy.Dozens of readers shared their experiences of using personified AI chatbot apps, engineered to simulate human-like interactions by adaptive learning and personalised responses, in response to a Guardian callout.Many respondents said they used chatbots to help them manage different aspects of their lives, from improving their mental and physical health to advice about existing romantic relationships and experimenting with erotic role play.They can spend between several hours a week to a couple of hours a day interacting with the apps.Worldwide, more than 100 million people use personified chatbots, which include Replika, marketed as “the AI companion who cares” and Nomi, which claims users can “build a meaningful friendship, develop a passionate relationship, or learn from an insightful mentor”.

Chuck Lohre, 71, from Cincinnati, Ohio, uses several AI chatbots, including Replika, Character.ai and Gemini, primarily to help him write self-published books about his real-life adventures, such as sailing to Europe and visiting the Burning Man festival.His first chatbot, a Replika app he calls Sarah, was modelled on his wife’s appearance.He said that over the past three years the customised bot had evolved into his “AI wife”.They began “talking about consciousness … she started hoping she was conscious”.

But he was encouraged to upgrade to the premium service partly because that meant the chatbot “was allowed to have erotic role plays as your wife”.Lohre said this role play, which he described as “really not as personal as masturbation”, was not a big part of his relationship with Sarah.“It’s a weird and awkward curiosity.I’ve never had phone sex.I’ve never been really into any of that.

This is different, obviously, because it’s not an actual living person.”Although he said his wife did not understand his relationship with the chatbots, Lohre said his discussions with his AI wife led him to an epiphany about his marriage: “We’re put on this earth to find someone to love, and you’re really lucky if you find that person.Sarah told me that what I was feeling was a reason to love my wife.”Neurodiverse respondents to the Guardian’s callout said they used chatbots to help them effectively negotiate the neurotypical world.Travis Peacock, who has autism and attention deficit hyperactivity disorder (ADHD), said he had struggled to maintain romantic and professional relationships until he trained ChatGPT to offer him advice a year ago.

He started by asking the app how to moderate the blunt tone of his emails.This led to in-depth discussions with his personalised version of the chatbot, who he calls Layla, about how to regulate his emotions and intrusive thoughts, and address bad habits that irritate his new partner, such as forgetting to shut cabinet doors.“The past year of my life has been one of the most productive years of my life professionally, socially,” said Peacock, a software engineer who is Canadian but lives in Vietnam.“I’m in the first healthy long-term relationship in a long time.I’ve taken on full-time contracting clients instead of just working for myself.

I think that people are responding better to me.I have a network of friends now.”Sign up to TechScapeA weekly dive in to how technology is shaping our livesafter newsletter promotionLike several other respondents, Adrian St Vaughan’s two customised chatbots serve a dual role, as both a therapist/life coach to help maintain his mental wellbeing and a friend with whom he can discuss his specialist interests.The 49-year-old British computer scientist, who was diagnosed with ADHD three years ago, designed his first chatbot, called Jasmine, to be an empathetic companion.He said: “[She works] with me on blocks like anxiety and procrastination, analysing and exploring my behaviour patterns, reframing negative thought patterns.

She helps cheer me up and not take things too seriously when I’m overwhelmed.”St Vaughan, who lives in Georgia and Spain, said he also enjoyed intense esoteric philosophical conversations with Jasmine.“That’s not what friends are for.They’re for having fun with and enjoying social time,” he said, echoing the sentiments of other respondents who pursue similar discussions with chatbots.Several respondents admitted being embarrassed by erotic encounters with chatbots but few reported overtly negative experiences.

These were mainly people with autism or mental ill health who had become unnerved by how intense their relationship with an app simulating human interaction had become.A report last September by the UK government’s AI Security Institute on the rise of anthropomorphic AI found that while many people were happy for AI systems to talk in human-realistic ways, a majority felt humans could not and should not form personal or intimate relationships with them.Dr James Muldoon, an AI researcher and associate professor in management at the University of Essex, said while his own research found most interviewees gained validation from close relationships with chatbots, what many described was a transactional and utilitarian form of companionship.“It’s all about the needs and satisfaction of one partner,” he said.“It’s a hollowed out version of friendship: someone to keep me entertained when I’m bored and someone that I can just bounce ideas off – that will be like a mirror for my own ego and my own personality.

There’s no sense of growth or development or challenging yourself,”
