Bright key facts / Demonstrated
Faster to start, but not the coach everyone wanted.
A 368-person diabetes study compared AI and human coaching: participants began sooner in the AI arm, while human coaching was liked more and 46.5% of the AI arm said they would have preferred a person.
- AI’s role
- An AI coach delivered structured guidance and follow-up in one study arm.
- Documented result
- Median time to start was 11 days with AI versus 26 days with human coaching. Human coaching received higher liking scores; 46.5% of the AI arm preferred human coaching.
- Important limitation
- The study does not show that shorter onboarding alone improves long-term health.
