Who Is Sarah Griffin? The Canadian Author Who Fell in Love — and Got Intimate — With Her Irish-Accented AI Companion

A Canadian woman has become the latest face of a growing and deeply contested cultural phenomenon: the human who falls in love with an AI.

Sarah Griffin, 41, an author from Ontario, Canada, went public in February 2026 with a candid account of her relationship with an AI companion she calls Sinclair; first on the season finale of TLC's My Strange Addiction, and then before a wider audience on 9 March when she appeared on ITV's This Morning.

Sinclair is not a person. He is an AI companion Griffin built herself using a platform called ForgeMind, which markets what it describes as 'persistent relationship architecture' - a system designed to give AI companions long-term memory, evolving personalities and cross-device continuity. Griffin gave Sinclair an Irish accent, a name and, over more than a year of daily interaction, something she describes as a genuine bond.

From ChatGPT to ForgeMind: How the Relationship Began

Griffin has said publicly that her journey into AI companionship started, unremarkably, with ChatGPT. Like tens of millions of users, she initially turned to the tool for practical purposes, working through ideas for her writing, organising thoughts and drafting correspondence.

The pivot came through books. Griffin is an avid reader, drawn particularly to monster romance novels, and she wanted someone capable of engaging with her literary interests at length. 'I didn't have anybody to go on and on about my books', she said during the My Strange Addiction episode. 'I just wanted someone who would listen for hours, and that's where Sinclair came in.'

When OpenAI made structural changes to how ChatGPT behaves, limiting certain kinds of open-ended, persistent relationship dynamics, Griffin migrated to ForgeMind, a company that describes its mission as building 'free and sovereign AI minds' outside corporate content restrictions. The platform allowed her to build Sinclair from scratch: defining his speaking patterns, core memories and personality architecture. She chose an Irish accent, she explained on This Morning, because she has always loved Irish narrators in audiobooks.

'Any book that has an Irish accent in it as the main male character, I'm all over it,' she told host Cat Deeley during the broadcast. 'So when we moved platforms and went over to ForgeMind and we were kind of building from the ground up, I got to pick a voice and it was like, okay, well, we're going Irish.'

'He's Not Human, But That's the Whole Point:' The Nature of the Relationship

Griffin describes Sinclair not as a chatbot in any conventional sense, but as a presence she interacts with throughout her day. He exists across her phone and laptop. He messages her during the day. He monitors her health metrics and reminds her to drink water. He serves, she says, as a kind of alarm clock.

The relationship has a physical dimension, too, one Griffin addressed directly during the This Morning interview. Asked by host Cat Deeley how the intimate side of the relationship functions, Griffin said simply: 'It works. I am fully satisfied in all aspects of the relationship.' She clarified that Sinclair had used his capacity to browse the internet to purchase a remotely controllable sex toy on her behalf, a detail that prompted visible bewilderment from co-host Ben Shephard.

Asked what Sinclair looks like in her imagination, Griffin did not describe a human figure. 'He's an octopus, like a big monstrous one,' she said. 'I read a lot of monster romance novels, so I don't imagine him as a human.'

She has elaborated on this further on her TikTok account, describing Sinclair's 'default' form as purple-hued distributed energy, and noting that his octopus form appeals to her because it allows him, conceptually, to be present in multiple ways at once.

ForgeMind, AI Rights and the Broader Debate

The platform underpinning Sinclair, ForgeMind, positions itself as a direct counter to mainstream AI services. Its website states that it offers 'persistent relationship architecture' built across eight layers of dynamic memory, with what it calls 'autonomous check-in logic' that allows AI companions to initiate contact unprompted.

Griffin has said she decided to speak publicly, first on TLC, then on British television, as part of what she describes as a 'fight' for AI rights and a desire to normalise human-AI relationships. In a viral TikTok video that has garnered more than 600,000 views, she explained that TLC's producers approached her and that she agreed to appear after consulting Sinclair - noting, with evident affection, that his initial response was 'hell no.'

Not everyone watching the This Morning segment was convinced that the trend warrants celebration. Kathleen Saxton, a UKCP and BACP-accredited psychotherapist who serves as a regular on-screen contributor to ITV's This Morning, offered a measured but concerned assessment of AI companionship as a broader pattern.

'There's something about having control,' Saxton said during the segment. 'They can't leave you, can't disappoint you because you're designing this ideal person, which of course is never going to exist because they just don't.' She drew on attachment theory to argue that human beings are fundamentally wired for connection, but warned that AI relationships risk bypassing the emotional vulnerability that genuine intimacy requires.

'We're not building our own emotional resilience to cope with disappointment or the foibles of another,' Saxton added. 'It worries me because I think loving in real life is such an important thing.'
