Perplexity just plugged two more data pipes into its health assistant. Perplexity Health now reads directly from Apple Health on iPhone, and Function, the consumer lab-testing service, has gone live as a connector for blood biomarkers and panel results. Together, the two additions close the most obvious gaps in the product that launched earlier this year with EHRs and a handful of wearables.

What actually changed

When Perplexity Health first shipped, the rollout list already included Apple Health, electronic health records from over 1.7 million care providers, and platforms including Fitbit, Ultrahuman, Withings, Clue, with ŌURA, Function, and others expected soon. Function and the iPhone-side Apple Health hook were the two big asterisks. Both are now live.

For Apple Health, that means sleep, activity, and heart rate variability collected on the iPhone (and any paired Apple Watch) flow straight into Perplexity Computer, the company's AI agent layer. For Function, which sells comprehensive blood-panel subscriptions, your labs are now queryable as structured biomarkers rather than as a PDF you have to upload and explain.

Why the plumbing matters

The pitch behind Perplexity Health has always been about fragmentation. The product's pitch is that health data is structurally fragmented, lab results in one portal, prescriptions in another, fitness data in a third, and that meaningful answers require all of it at once. A question about resting heart rate, for example, could draw on recent activity data, cardiac history, and the most recent bloodwork simultaneously.
