Perplexity health launches ai medical assistant using wearable data

Perplexity adds a fresh layer to its AI network - enter Perplexity Health, built to tackle tough medical questions with clear, science-backed replies. Instead of generic guesses, it pulls information from fitness trackers and health apps, stitching together details like heart rate or sleep patterns into custom feedback. Because it taps directly into your day-to-day metrics, responses shift with your body’s signals. Precision comes not from assumptions but from real-time inputs tied to how you move, rest, and feel. Each answer shaped less by broad trends and more by what your own physiology shows. It’s tech that listens closely, then speaks with context. Not magic - just careful connections made visible.

It works by pulling health info from various outside apps to track how exercise, rest, and eating habits change over time. Because it uses an advanced AI called Perplexity Computer, the tool makes sense of that data to offer personal advice - like workout plans or food choices suited to individual needs. One key part of its design is tight linking with Apple Health, so the AI can compare current concerns with past records while answering health-related queries.

One way to handle worries about precision in healthcare? Perplexity built its systems using loads of real medical information. Its training draws from published research, expert-approved studies, care protocols, alongside patient files used daily by over 1.7 million clinicians worldwide. Instead of general web answers, it leans on proof checked by doctors and scientists. The goal shows clearly - trust comes from grounding responses in what medicine already knows.

Right now, the launch happens step by step - starting with Pro and Max users in the U.S. Health info can sync up to Apple Health, Fitbit, Ultrahuman, plus Withings, yet more links are coming soon, including Oura and Function. Not long after teaming up with Samsung, where their AI became part of Galaxy AI, this move takes shape.
