Common questions

We are a behavioural science and AI consultancy for digital health and GLP-1 teams. We design, evaluate, and safely deploy the behavioural layer that makes patient-facing AI actually change behaviour, so teams improve adherence, retention, and outcomes.

It is the layer that helps AI change behaviour safely and effectively in real-world health settings: the strategy, decision logic, tone, timing, framing, and support that determine whether patients trust, use, and stick with an AI system.

A chatbot answers questions. Behavioural AI is the layer around and beyond it: the design and logic that decides what support a patient needs, when they need it, and how it should be delivered so it actually changes behaviour, safely. Most of our work is that layer, not the chatbot itself.

Both. We work from strategy through to hands-on design, delivery, and evaluation of AI systems, often as an extension of your team.

Digital health, GLP-1 and obesity, and behaviour-change teams building or deploying patient-facing AI. All of our current client work is in GLP-1 and weight management.

GLP-1 medicines work only while patients stay on them, and most stop within the first year, mostly for behavioural reasons. We design the behavioural layer, the onboarding, timing, tone, nudges, and support, that keeps patients engaged and progressing, and we evaluate what actually moves adherence, persistence, and long-term maintenance.

Yes. We run independent behavioural and clinical evaluation, including PromptSafe simulation testing, to find safety, quality, and behavioural gaps before or after launch.

PromptSafe is our AI safety and quality testing tool. It runs offline simulation testing of conversational AI agents across hundreds of realistic and adversarial conversations to find where they fail users before real users do.

FAST is our published framework (Frontiers in Digital Health, 2025) for evaluating conversational AI health coaches across four domains: fidelity, accuracy, safety, and tone.

Yes. We design and run clinical and behavioural research, from study design to peer-reviewed publication, to build credible evidence of effectiveness, safety, and impact.

Engagements are scoped to your goals, from a focused strategy sprint to longer delivery or research programmes. The best next step is usually a short discovery call to work out the simplest useful starting point.

An unusual combination in one place: decades of clinical and behavioural science credibility, peer-reviewed research, and hands-on AI delivery and safety. And independence, because we own no platform we need to sell.

Yes. We own no platform or app, so our advice is based on what works, not on what we have to sell.

We are a UK-based consultancy (Capital Consult Ltd, trading as Sacher AI), working with digital health teams internationally.
