Perplexity Health has launched Function, an AI-powered connector that integrates users’ scattered health data (from wearables, EHRs, labs, wearables, apps) and turns it into highly personalized, actionable insights. The tool aims to deliver clinician-grade recommendations, early risk detection, longitudinal trend analysis, and guided next steps without replacing professional medical advice addressing the growing challenge of fragmented health data in consumer and clinical ecosystems.
Glimpse:
Function securely pulls data from major sources (Apple Health, Fitbit, Google Fit, Epic MyChart, lab portals, etc.) using FHIR and other standards, then applies Perplexity’s advanced reasoning models to generate plain-language summaries, predictive alerts (e.g., rising glucose trends + poor sleep = higher diabetes risk), lifestyle suggestions, and questions to ask doctors. It emphasizes transparency (full source citations), privacy (on-device processing where possible, end-to-end encryption), and clinician oversight (outputs are informational, not diagnostic). The feature is now live in the Perplexity Health app for early users, with broader rollout planned soon.
Perplexity Health, the health-focused arm of the Perplexity AI platform, has officially introduced Function a powerful AI connector designed to unify and interpret fragmented personal health data into clear, personalized insights. The launch, announced on February 27, 2026, addresses a widespread pain point: most people have their health information spread across wearables, fitness apps, electronic health records, lab portals, and manual logs, with no easy way to see the full picture or understand what it means for their wellbeing.
Function acts as an intelligent bridge: users grant secure, consent-based access to their data sources (via FHIR APIs, Apple Health, Google Fit, Fitbit, Garmin, lab portals like Quest/Labcorp, and EHRs like Epic MyChart), and the AI aggregates, normalizes, and analyzes the information in real time. It then produces concise summaries, trend visualizations, predictive risk flags (e.g., “Your HRV has dropped sharply this week alongside poor sleep increased cardiovascular risk possible”), personalized recommendations (nutrition, exercise, sleep adjustments), and suggested questions to discuss with a doctor. The system draws on Perplexity’s advanced reasoning models fine-tuned on medical literature and anonymized health datasets, always citing authoritative sources (PubMed, clinical guidelines, etc.) for transparency.
The platform has been built with strict privacy and safety in mind: no raw health data is stored long-term without consent, processing occurs with strong encryption (on-device where feasible), and all outputs carry clear disclaimers that they are informational only not medical diagnoses or treatment plans. Clinicians remain essential, and Function encourages users to share insights with their doctors for professional review. Early user pilots have shown strong engagement, with many reporting better understanding of their health trends, earlier conversations with providers, and improved adherence to lifestyle changes.
The launch comes amid growing consumer demand for tools that make sense of scattered health data, especially as wearables and remote monitoring become mainstream. Perplexity Health positions Function as a “personal health co-pilot” that empowers users while supporting rather than competing with the healthcare system. The feature is currently rolling out to Perplexity Health app users in the U.S. (with international expansion planned), and the company is actively partnering with health systems, insurers, and device makers to deepen integrations and generate real-world evidence on its impact.
This move reflects Perplexity’s broader ambition to evolve from a search engine into a comprehensive knowledge and decision-support platform, with healthcare as a flagship vertical. Industry observers see it as a timely and potentially disruptive step in consumer-facing health AI, provided it maintains rigorous accuracy and privacy standards.
“Your health data is already everywhere but it’s useless until it tells you something meaningful. Function turns that scattered information into clear, personalized guidance so you can act before problems become serious.”
