AI chatbot aims to boost steps and blood sugar control in diabetes
NCT ID NCT06596330
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial tests whether an AI language model, similar to ChatGPT, can generate personalized coaching messages that encourage people with type 2 diabetes to walk more. Participants use the My Heart Counts smartphone app and receive AI-generated prompts tailored to their age, gender, race, and readiness to change. The study will measure daily step counts over a week and then over 24 weeks, also tracking weight and HbA1c levels to see if the coaching leads to lasting improvements in blood sugar control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AI-generated coaching prompts delivered through the My Heart Counts smartphone app
- What this could lead to
- If it works, this could point toward a scalable, low-cost digital tool to help people with type 2 diabetes become more active and improve blood sugar control.
- What could go wrong
- The trial is early and relies on self-reported activity and app engagement, which may not translate to lasting behavior change. The AI prompts may not be more effective than standard advice.
