ChatGPT's new Health feature reads your medical records—across any conversation

OpenAI is now connecting ChatGPT directly to your Apple Health data and medical records, and the company’s decision to do so came down to one number: 70 percent. That’s how many health-related chats during an early test happened outside the dedicated health space, buried in meal planning sessions or random symptom queries. So instead of siloing the feature, OpenAI is embedding it everywhere.

Users 18 and over can now link accounts from Apple Health, US hospital systems, One Medical, or Function Health. Once synced, ChatGPT can silently pull medications, lab results, sleep data, and activity logs into any conversation. It’s a dramatic shift from the earlier design that required opening a separate tab to get data-grounded answers.

Early testers describe the tool as something between a research analyst and a translator. Blake, a technical program manager, said it turned “scattered medical history into something I can actually understand and explain,” connecting overlapping issues into a clear timeline. Reweti, a portfolio manager, zeroed in on longitudinal analysis as the killer feature: “It’s like having a research analyst.” But nurse Shannon flagged the product’s sharpest edge—finding an unexpected chart entry through the tool, which she now plans to follow up on with a real doctor. That’s the tightrope OpenAI must walk as this scales.

The company is framing the feature as support, not diagnosis. The Health tab remains, but its role has shrunk to a management hub for reviewing trends and reconnecting accounts. For users like Kathleen, who lost a decade-long fitness habit, the value is simpler: ChatGPT sees she hasn’t worked out in seven days and suggests a walk, not a sprint. It’s mundane, but that mundanity might be the point.
