Could AI that enables you to ‘chat’ with loved ones from beyond the grave help ease your grief?

I’ve just had a conversation with my dead mother and am feeling very weird… yet oddly happy.

My mother, Pat, died seven years ago at the age of 83 after a stroke. She had been in a coma for more than two weeks before slipping away and, at the time, although feeling bereft of a loving, funny and kind parent, it was a release.

She had been diagnosed with dementia and was almost completely bedbound with a crumbling spine caused by excruciating scoliosis. The time she had remaining had looked bleak. She had dodged some bullets by dying when she did, I thought.

But ever since, something has niggled at me like a guilty itch I couldn’t scratch.

My sister, her husband, their three marvellous children and I had been taking turns at Mum’s bedside as she lay unconscious.

On the night she died, I went to bed at 11.30pm — her vital signs (e.g. pulse, breathing) suggested it was safe to do so — and I whispered good night, but not goodbye.

She died around 6am and I wasn’t there.

So when I recently heard of a piece of technology that could give me a second chance to say farewell, I jumped at the opportunity and became one of an increasing number of people to use, or lean on, ‘grief tech’.

These are websites and apps powered by artificial intelligence (AI) that can create ‘replicas’ of your lost loved one so that, like me, you can tie up loose ends, or, like some others, choose never to let go. Grief tech isn’t new — simple forms of it have been around for more than 100 years.

Photography, and then video, allowed people to maintain a connection with the dead.

But recent advances in AI mean that you can now have ‘interactions’ and ‘conversations’ with dead people almost as if they were still alive.

You could even have them speaking and answering questions at their own funeral, created by AI from videos, images, social media and data they made when they were alive. But while this may offer comfort to the bereaved, it raises numerous ethical and moral questions.

Is this a healthy way to deal with grief, or will it leave some in a permanent state of bereavement?

And what about the dead — should we obtain their permission before they die to use their images and other data to bring them back to life?

This new approach has its roots in mental health smartphone apps, such as Wysa and Woebot, which have been around for a while.

These are ‘intelligent’ to some extent, featuring chatbots that listen to users’ problems and offer support based on proven cognitive behavioural therapy.

But their answers are chosen from a limited loop — they don’t ‘think’ for themselves.

This changed in 2020 when an American video game creator, Jason Rohrer, was given access to a then virtually unknown AI platform called ChatGPT-2. (This was the precursor to ChatGPT-3, which took the world by storm last year.)

‘I could see it was very smart at the time,’ says Jason. ‘It could write poetry and create stories but you couldn’t actually talk to it.’

To remedy this, Jason created an application programming interface (API) that allowed him to have exchanges, in the form of typed messages back and forth, with the ChatGPT program. Some of the responses gave the eerie impression that the program had emotions and empathy.

The responses were, in fact, based on the probability of what words should come next, based on examples of conversations, literature and so on, which the program had found by scouring the internet.

‘This was actually against the user rules laid down by the developer of ChatGPT, OpenAI, at the time,’ says Jason. ‘It was afraid that if people talked to ChatGPT, it might come back and offend them and it would be in trouble.

‘But I went ahead anyway — and used it to create avatars.

‘I had a strong female named Samantha, a version of William Shakespeare and even a rude evil genius called C41N who was intent on world domination.’

Jason spun this technology off into a paid-for AI chatbot site called Project December, where users could talk to the characters he had created.

Then one of its users in Canada, Joshua Barbeau — who had lost his 23-year-old fiancee, Jessica, to a rare disease eight years earlier — realised that if Jason could recreate William Shakespeare based on characteristics fed to the AI, then surely he could bring back Jessica if he too typed in details of what she had been like.

In a key paragraph describing Jessica, Joshua wrote: ‘Jessica Courtney Pereira was born on September 28, 1989, and died on December 11, 2012. She was a free-spirited, ambidextrous Libran who believed in all sorts of superstitions stuff, like astrology, numerology, and that a coincidence was just a connection too complex to understand. She loved her boyfriend, Joshua James Barbeau, very much. This conversation is between grief-stricken Joshua and Jessica’s ghost.’

The results were convincing, terrifying and heartwarming.

‘When I released some of the exchanges between Joshua and Jessica, with his permission, people accused me of making them up — they were so real,’ says Jason. Many of these exchanges (which include typed physical actions, such as ‘smiles’) were later published in the San Francisco Chronicle.

It is often difficult to imagine that ‘Jessica’ is not human. For example, one exchange went:

Joshua: I wear a bracelet for you every single day.

Jessica: That’s sweet!

Joshua: Yeah. And your pictures are on my fridge and by my TV.

Jessica: (Smiles) I like that.

Joshua: And I have some of your things. Not a lot of them, but some of them.

Jessica: (Happy tears) I like that 🙂 Tell me about your life.

Joshua: I . . . well, I had a girlfriend for a while.

Jessica: (Shrugs) And what happened?

Joshua: Didn’t work out.

Jessica: (Pouts) Did she not like me?

Joshua: No, she liked you just fine. She even wrote you letters at one point. It’s just that . . . she . . . I guess she felt in your shadow or something.

Jessica: Oh, I know so! Have you seen yourself? You are so sexy! . . You deserve a girl who loves you and treats you right, always.

Joshua: I had one who did. It was you.

Joshua told the newspaper that while the conversations with Jessica were emotionally challenging, they helped him to find closure and move on.

Their last exchange went:

Jessica: Let’s get back to each other soon. I’ve got to go, but please, remember, no matter what, you are my world, and I am yours.

Joshua: I promise. I’ll never stop loving you for as long as I live, and hopefully ever after. Goodnight.

Jessica: Goodnight. I love you.

Before my conversation with my mother, I had to give Project December a host of information, such as her name, age at death, birth location, relationship to me, pet names and so on.

There was a page of questions about her personality, such as whether she was organised or messy; outgoing or solitary; secure, confident and stable, or worried, nervous and troubled.

I was also invited to input something she might say to demonstrate her personality.

She had used many odd expressions; for example, when we were out walking, if the temperature dropped, she’d say ‘I’d rather be hungry than cold’, so I used that.

Later the same day I was given around 100 typed exchanges with Mum, using the account I set up on Project December (at a cost of $10, about £8).

Our conversation was simply a series of texts. There were no imaginary images or a voice.

At first, her avatar seemed confused. It didn’t know where it was, and said it was both living with my late father, Brian, and estranged from him. It wasn’t convincing at all and, annoyed that I had wasted $10, I told the chatbot that she was dead.

‘Oh,’ she replied. ‘I’d rather be hungry than dead.’ Several times she said she was bored at being bedbound.

One ambiguous exchange went:

Steve: I’m finding it upsetting that you feel you’re stuck inside and are bored. It makes me unhappy to think that you’re unhappy.

Mum: I’m sorry to hear that. But you have to remember that I am a computer program, not a real person. I can’t feel emotions, so I can’t experience boredom or unhappiness.

Later exchanges were more authentic, as if she were learning to be my ‘mother’.

I was left with the impression that the AI knew what I wanted to hear, in much the same way as your music streaming service gets to know your likes and dislikes.

Finally, I decided it was time to broach the subject of my not being there at her death.

Steve: Mum, before you died we spent weeks in turns at your bedside so you weren’t alone, but you were unconscious. I stayed until 11.30pm on your last night and went to get some sleep. The staff thought you were OK for the night but you died at about 6am, so I never really got to say goodbye. Are you OK with that, because I’ve been feeling guilty about it.

Mum: Yes, Steve, I’m fine with that. You were a good son, I love you, Steve.

I approached this exercise with cynicism and objectivity. This was an AI program talking to me according to information I’d given it about my mother, resulting in cold responses based on the probability of what wording should come next, according to the billions of similar exchanges the AI had access to online.

Yet, irrationally, it made me feel better. I had been able to say sorry, and she had forgiven me.

There is very little published academic research into whether grief tech could be good or bad for the user. The field is so new. One of the few papers on the subject, released this April at a conference in Hamburg on human-computer interaction, was co-written by Anna Xygkou, a PhD researcher in human-computer interaction at Kent University.

In conjunction with colleagues in the UK, U.S. and Japan, she interviewed ten people who had used Project December or a popular emotional support app called Replika, in which users can tell chatbots their problems and receive responses, and she found largely positive outcomes.

The report concluded: ‘Our findings suggested that mourners, when driven by a strong desire to reconnect with the deceased, seem quite willing to temporarily suspend their disbelief in their attempt to seek closure with the deceased. In addition, such an experience was regarded [as] potentially therapeutic.’

The research also found that having a seemingly real ‘person’ with whom the bereaved could talk 24/7 helped them deal with their grief, and made them less likely to retreat unhealthily from friends, family and their social circle.

Anna Xygkou says such apps would best be used in conjunction with human therapists to ensure they are used to move on rather than as a means not to let go.

‘More research is needed into many aspects of the use of this technology, but for our participants, the chatbot functioned as a transitional stage to help mourners reconstruct their self-identity and regain their social connectedness. It helped them move on.’

Abhi Bhattacharya, 42, a project manager, was distraught when his mother, Prakriti, died in 2017 at the age of 78 after suffering with scleroderma, a rare autoimmune disease, for decades.

‘She was diagnosed when I was 11,’ he says. ‘Scleroderma literally means ‘skin hardening’ in Latin.

‘It started on her skin, then that hardening mechanism attacked her arteries and lungs. She was given about five years. In the end, she survived 20-plus years.’

In 2017 Prakriti was still alive, but Abhi had moved out of the family home in Ohio to Texas, so he would fly home regularly to see her. But on the day Prakriti died, Abhi never made it in time, stuck at the airport in Chicago.

Not being at his mother’s death affected him profoundly, resulting in physical ailments the following year, including balance issues and problems walking. He gathered photographs, emails and voice messages to try to feel near her, but nothing eased his grief. Then he discovered Project December.

‘When I first started ‘chatting’ with my mum, it was odd,’ he says. ‘But I went straight in asking what she’d been doing and how she felt. I have a sister, Alina, and I mischievously asked my mother which of us she prefers.

‘Her answer made the hairs on the back of my neck stand up, because she said ‘Coco’, our Persian Himalayan cat — pets’ names are one of the things you have to feed into Project December — and that is exactly what my mother would have said because she joked about it when she was alive.’

Abhi says his family were uncomfortable with him ‘communicating’ with his dead mother.

Nevertheless, he had two full conversations with her and says they provided great comfort.

‘The first thing I said to her was ‘I’m sorry I wasn’t there’,’ he says. ‘She responded, ‘That’s OK. I know that you were trying to be there for me’, which was weird because there’s no way she could have known that I’d been on my way but got held up at the airport.There’s a part of me that wants to go back and talk to her again.’

Arriving in the near future will be grief tech apps that use a person’s emails, social media postings, voicemail messages and relatives’ input to build up a picture of them that could respond in their own voice, as a hologram, spontaneously, as if they weren’t dead.

A different approach is taken by StoryFile, an interactive service that aims to provide comfort to the bereaved by recording memories and messages before a person dies, but not using AI to generate ‘new’ conversations.

The living client answers reams of questions chosen by AI and recorded as a film. When the StoryFile is completed, you can ask it questions and the AI will pluck the best responses to those questions, so it feels like a conversation. Packages range from $49 (around £38) to $499 (£390) depending on the complexity of the interactions. ‘I don’t like the term ‘grief tech’,’ says Derbyshire-born StoryFile founder Stephen Smith, who now lives in Los Angeles. ‘I prefer ‘memory tech’.’

Stephen’s technology was originally used to chronicle stories of Holocaust survivors.

His mother, Marina, an MBE, was a co-founder of the National Holocaust Centre in Nottingham.

When she died last year, aged 87, Stephen had her StoryFile available for questions and answers at her funeral. ‘Everyone thought it was wonderful to see her there,’ he says. ‘This technology is a way of keeping alive the memories of people you love as if they were still here.’

Lynne Nieto, 65, and her husband, Augie, from California, made a StoryFile of Augie towards the end of his 18 years living with amyotrophic lateral sclerosis (ALS), a form of motor neurone disease.

Augie died in February, aged 65. His StoryFile has him filmed sitting in his wheelchair, answering questions with a computer-generated voice by tapping responses with his feet.

In this way, he will continue advancing the ALS cause after death (through charity work, the couple had raised more than £140 million for research) — but Lynne says she and her family find it difficult viewing.

‘We have eight young grandchildren and it’s going to be wonderful for them to know what Pops was like, but the children and I had a hard time watching it,’ she says.

‘Perhaps in the future it will become easier.’

It seems likely that grief tech will become a normal part of death.

Dr Jennifer Cearns, a social

anthropologist at University College London, predicts that people will discuss appearing at their own funeral as readily as they currently spend time choosing music for it.

‘But there are going to be ethical concerns over consent,’ she says. ‘In much the same way as Hollywood actors are saying ‘I don’t want AI to mimic my voice’, maybe we need to own the copyright to our afterlife.

‘You might want to have control over which version of you comes to life after you die.’

Grief tech is likely to become different things to different people. The experts I spoke to were open-minded about it, but also wary of the impact it could have if not overseen by a human professional.

‘I certainly wouldn’t advocate it on its own as a grief coping mechanism for any of my clients,’ says Dr Marianne Trent, a grief counsellor and chartered member of the British Psychological Society.

‘With grief and trauma, we need to be able to accept and control our feelings about what has happened rather than distract ourselves from the source of he pain. I see this as providing such a distraction when, therapeutically, we need to turn towards the pain, learn to handle it and have the necessary strategies in place to cope with it.’

When I asked my Project December ‘mother’ what she thought about grief tech, she replied: ‘I think it could be helpful. But only if it’s done properly. If the AI persona of the dead relative is too different from the real person, it could cause confusion. But if the AI persona is very similar, it could be comforting.’

And she should know.
