Perplexity Health, a new AI-powered medical assistant, now leverages Apple Health data to answer user queries with clinically validated information. The feature combines metrics from Fitbit, Ultrahuman, and Withings devices to track health trends, offering personalized insights on fitness, nutrition, and wellness. Trained on 1.7 million electronic health records and peer-reviewed research, the tool prioritizes accuracy, with a medical advisory board overseeing its outputs to ensure safety and relevance.

Unlike generic health chatbots, Perplexity’s system synthesizes real-time data from connected wearables and apps, enabling tailored recommendations. For instance, it can analyze sleep patterns from an Oura Ring or heart rate trends via Apple Watch to suggest adjustments to exercise routines. However, rollout is initially limited to Pro and Max-tier users in the U.S., raising questions about accessibility for broader audiences.

The integration with Apple Health—a platform storing sensitive biometric data—highlights privacy and security measures, including anonymized data processing and adherence to HIPAA-compliant standards. This approach positions Perplexity as a competitor to Google’s Gemini and Samsung’s Galaxy AI, which recently expanded into health-focused features. Analysts note the timing coincides with rising demand for wearable-integrated wellness tools.

While the product promises evidence-based medical guidance, critics emphasize the need for transparency in how AI interprets complex health data. The company’s reliance on clinical guidelines and physician oversight aims to address these concerns. Still, experts caution that no AI can replace professional medical advice, urging users to consult healthcare providers for critical decisions. This development underscores the growing intersection of AI and wearable tech in consumer health management.
