Meet Primary

AI-Powered Continuous Care

Every year, 41 million die too soon – and over a billion live with the burden of chronic disease.
That’s the legacy of today’s healthcare. Reactive. Episodic. Too late to make a difference.

At 78Health, we’re using AI to put continuous, intelligent care in your hands to keep you healthy.

How it works

At its core, Primary organizes all health data—including biomarkers, wearable device data, food logs, and medication records on a unified timeseries. This acts as the foundation for the set of AI health agents that work together to interpret user inputs and perform actions on your behalf. Another group of AI agents autonomously identify key health issues, changes in risk profile and other relevant patterns in the data to generate timely interventions.
