Evidence based digital CBT

Real psychology, written by a clinician, not generated by a chatbot.

AICBT has been building digital cognitive behavioural therapy since 2007, validated by multiple randomized controlled trials and 14 peer reviewed publications with university research partners on three continents. Every word is written and sequenced by a licensed clinical psychologist, not generated by AI.

The home of digital CBT, built on evidence.

AICBT builds cognitive behavioural therapy that people can use on their own, backed by evidence anyone can check. It began in 2007, years before "digital mental health" was a category, when clinical psychologist Dr. Fjóla Helgadóttir taught herself to code to build the first version. Today AICBT Ltd is directed by Dr. Fjóla Helgadóttir and Neil Yager, and the approach hasn't changed: build a program grounded in decades of clinical technique, test it, publish it, then improve it. That work began with Overcome Social Anxiety, the long running flagship now licensed by US universities. With newly published research in 2023 and 2026, including a randomized controlled trial, we are confident calling Overcome Fertility Stress evidence based, and we are now opening it up to fertility clinics and to everyone who finds their way here. A book on misophonia is on the way too.

01

Clinician written

Every module and chapter is authored by a licensed clinical psychologist, never AI generated, never generic wellness filler.

02

Tested and published

The methods are put through peer review and randomized trials, then cited openly, not just claimed on a landing page.

03

Yours to use anywhere

Self paced, private, and available without a referral or waiting list, built to run alongside the care you already have.

We were AI before AI meant chatbots.

The AI in AICBT stands for the adaptive intelligence built into the programs since 2007: carefully designed logic that personalizes clinician written therapy to each person's answers. There are no large language models, no chatbots, and no generated responses anywhere in the therapy. Every word was written in advance by a clinical psychologist, and the technology decides only which of those words you need next. In an era of AI wellness apps spun up in a quarter, that difference is the whole point.

This is not a recent pivot. Back in 2009, Dr. Helgadóttir published a pair of first authored papers in Behaviour Change on bridging the gap between Eliza, the original chatbot, and genuine online CBT, over a decade before the current wave of AI therapy apps existed.

Misophonia: a book in progress.

Forthcoming Misophonia Dr. Fjóla Helgadóttir

Some sounds don't just annoy you. They take over. Misophonia is real, common, and badly misunderstood. Dr. Fjóla Helgadóttir is writing a book that explains what it is, why it happens, and what actually helps, from a clinical psychologist who treats it.

The book is being written now, with publication expected by the end of 2026. Sign up to follow along and be first to know when it launches.

Writing in progressExpected late 2026

Tested. Published. Not just claimed.

RCTs Multiple randomized controlled trials across the AICBT programs, published in peer reviewed journals
2.7 Effect sizes reported around 2.7, where face to face CBT typically reaches 1.0 to 1.5

The work behind AICBT rests on 14 peer reviewed publications and several randomized controlled trials, developed alongside university research partners. Dr. Helgadóttir's research has been cited 852 times by scientists worldwide (Google Scholar, h index of 15), a body of work stretching back to her first authored papers on online CBT in 2009, cited below. In the most recent trial, published in the Scandinavian Journal of Psychology, women using Overcome Fertility Stress showed a significant reduction in infertility related stress with a large pre to post effect size (Cohen's d = 1.70), while the control group showed no significant change.
