Perplexity, the AI search company that has been building out a suite of connected vertical tools since early 2026, this week launched Perplexity Health — an AI-powered health assistant that can connect directly to your Apple Health data, medical records, and wearable devices to answer personalized health questions. It is the latest company to enter the AI health space, following OpenAI’s ChatGPT Health in January and Microsoft’s Copilot Health just last week.
What Is Perplexity Health?
Perplexity Health is an expansion of Perplexity Computer, the company’s AI agent platform. It gives Perplexity permission to read from your connected health data sources and use that data to generate personalized answers to health questions.
Instead of giving generic answers based on training data alone, Perplexity Health answers from your actual information. A question about your resting heart rate, for example, can factor in your recent activity data from Apple Watch, your cardiac history from connected medical records, and your latest bloodwork — all at once.
What Can It Connect To?
At launch, Perplexity Health supports the following connectors:
- Apple Health — integrates data from Apple Watch and anything stored in the Health app on iPhone or iPad
- Electronic health records from over 1.7 million care providers
- Fitbit, Ultrahuman, Withings, and Clue (wearables and health platforms)
- ŌURA and Function — coming soon
- Additional connectors via partners including b.well and Terra API
Once connected, Perplexity Health generates a personalized dashboard that tracks metrics and trends across biomarkers and activity data over time.
What Can It Actually Do?
With health connectors active and Perplexity Computer running, AI agents can use your data to generate practical outputs including pre-appointment visit summaries, personalised nutrition plans based on your metabolic data, marathon training protocols built around your fitness history, and explanations of lab results in plain language.
Perplexity says all responses draw from clinical guidelines and peer-reviewed journals with citations linked to source material — and include guidance on when users should seek professional medical care rather than rely on the AI.

Perplexity has established a Health Advisory Board of physicians, researchers, and health technology leaders whose stated role is to pressure-test product decisions, content quality, and clinical safeguards. The company is explicit that Perplexity Health is not a diagnostic tool and is not a substitute for professional medical advice.
Should You Connect Your Apple Health Data?
This is where it gets complicated.
On the privacy front, Perplexity says health data is encrypted in transit and at rest, with strict access controls, and that it is never used to train AI models or sold to third parties. You can disconnect sources at any time.
On the practical front, the value depends heavily on how much data Apple Health and your connected devices actually contain. If your iPhone tracks your steps, sleep, and heart rate via Apple Watch, and your doctor’s office uses a connected EHR system, Perplexity Health will have meaningful data to draw from. If you mainly use Health as a step counter, the answers will not feel much more personalized than a generic query.
It is also worth noting that Washington Post testing of the comparable ChatGPT Health found the AI occasionally reported things that were not backed up by the actual data it was given — a caution that applies equally here.
Perplexity Health is rolling out to Pro and Max subscribers in the United States first, initially on iOS and at perplexity.ai/health on the web. Broader availability across other tiers and regions is expected over time.
