Virtual Krissy is AI, built on Kristen’s clinical approach. It gives general guidance, not personal clinical advice — anything clinical goes to a qualified practitioner.
Physio-designed guidance. Accessible to everyone.
Traditional 1:1 coaching with a physiotherapist and nutritionist is genuinely valuable — but it’s expensive, geographically limited, and only available during clinic hours. Hi Krissy brings Kristen’s evidence-based approach to an AI-powered platform that costs a fraction of ongoing 1:1 appointments, adapts as you go, and is available 24 hours a day, 7 days a week, anywhere in the world.
Adapts as you go
Your plan adapts to your goals, your body and how busy your week actually is — no two people get the same experience.
Evidence-based recommendations
Hi Krissy is built on clinical research and Kristen Witt’s experience as a qualified physiotherapist and nutritionist — not wellness trends.
Available 24/7
No appointment needed. Chat with Virtual Krissy, review your plan, or log your progress whenever it suits you — early morning, late night, weekends included.
Affordable ongoing support
Ongoing nutrition and movement coaching without the cost of regular 1:1 appointments. See current plans ↗

Expert guidance shouldn’t be a luxury
Hi Krissy was created by Kristen Witt because she kept seeing the same problem in clinic: people who understood that nutrition and movement mattered, but couldn’t access consistent, expert guidance between appointments. A session once a fortnight wasn’t enough. Generic meal plan PDFs weren’t personal enough. And for many people, the cost of ongoing 1:1 coaching simply wasn’t realistic.
Kristen built Hi Krissy to solve that. By combining her clinical expertise in physiotherapy and nutrition with AI that learns as you go, Hi Krissy makes evidence-based nutrition and movement guidance available to anyone — at a price that doesn’t create another barrier to getting healthy.
