A new connector lets Function Health members bring lab results and biomarker trends straight into Meta’s personal AI agent, Muse.
A particular kind of frustration is getting a stack of lab results back and not really knowing what to do with them. The numbers are there, the ranges are there, but turning that into an actual plan usually means either a follow-up appointment or a lot of solo googling. Function Health, the Austin-based company built around large-scale biomarker testing, wants to close that gap by handing your data to an AI that already knows the context [1].
Function announced that members can now securely link their Function health data to Muse, Meta’s newly launched personal AI agent. Muse joins ChatGPT, Claude and Perplexity as the fourth AI platform in Function’s connector network, meaning members increasingly get to choose which AI assistant they want managing their health context, rather than being locked into one [2].
Once connected, Muse can draw on a member’s lab results and clinician-reviewed summaries to help interpret what’s going on, build or adjust plans toward specific health goals, and follow up on progress over time. Function has made it clear that members stay in control of their own data throughout.
“Your AI should know your biology,” said Jonathan Swerdlin, CEO and co-founder of Function. “By connecting Function health data to Muse, people can bring a living picture of their health into the AI platforms they use every day. We are entering a world where people understand their bodies in far greater detail and increasingly rely on AI to make decisions. Bringing those together makes AI dramatically more useful.”
How the connection actually works
Setting it up happens from inside Meta, through the same account controls members already use to manage other account data, so there’s no separate app or extra login required. Once it’s authorized, Muse pulls in a member’s Function results and can be used in a few concrete ways: asking how a specific lab result compares to a personal optimal range before acting on it, building or adjusting a plan around a goal using that person’s own data as context, and flagging when it’s time to book the next lab visit, then following up until it’s actually on the calendar.
That last piece is arguably the most useful one, honestly. Most health tracking falls apart not because people don’t care, but because nobody follows up. An AI that nags you, gently, until you rebook a test is solving a very ordinary, very human problem.
Part of a bigger shift
Function’s broader pitch has always been about giving people biannual access to more than 160 lab tests for $365 a year, working out to about a dollar a day, covering everything from heart and thyroid markers to kidney function, inflammation, and early cancer signals. Members can also pay extra for MRI and CT scans designed to catch signs of cancer and other conditions early. The company describes its mission plainly: helping people live 100 healthy years.
That mission is exactly why this particular partnership matters more than a typical tech integration announcement. Longevity science keeps circling back to the same idea: that the earlier you catch a problem, the more room you have to actually do something about it. Biomarker testing only helps if someone actually acts on what it shows them, and that’s historically been the weak link. Most people don’t have a personal physician checking in on their cholesterol trend line every week. An AI agent that actually can, using your real numbers instead of generic advice, is a meaningfully different kind of tool than a chatbot answering questions in the abstract.
It also says something about where consumer AI is heading generally. A year or two ago, most people’s interactions with AI assistants were fairly disconnected from anything personal. Increasingly, the winning products are the ones plugged into a person’s actual data, whether that’s a calendar, a bank account or, now, their own biology. Function’s health connector rolls out over the coming weeks, and if the early framing holds, it’s a preview of what a lot more health platforms are likely to start doing.
