I feel you can’t just dump in the CSV values from your Xiaomi Scale and Garmin watch… And hope AI will figure out the correct math on your body… And then also come up with good recommendations.
As far as I know, there are a few local, selfhosted health trackers available. It’s a bit tricky to own the correct gadgets that connect to it… But I don’t think there’s anything with AI.
I mean to give proper recommendations, you’d need a very elaborate setup. It needs all the sensor values. Then correlate it with what you’re doing all day long… What you eat and how much you drink… The AI (or traditional algorithms) can’t see. So maybe it can calculate your BMI in a thinking step. But it’s a whole lot of math to then figure out if your too fat, or have muscle mass… And then find out what that means for your diet. AI won’t figure that out along the way. So you’re probably looking at a few thousands of lines of code, after reading a few textbooks on biology.
I mean you can try to vibe-code some agent. But I think your best bet is to look for some open-source software cloning Google Health, or something like that. (And then maybe you can write some MCP server for that. And an agent to interpret the aggregated results.)





It wasn’t really clear to me where you want to go with this. I mean judging by conversations with my friends, there’s a 3h conversation to be had about every nuance of health. The diet, how to work out, how much to eat and drink. There’s rules of thumb. But in reality it’s a very individual thing. And also changes with the situation, for example if you go to the gym or running and want to progress, it’d be an entirely different story a few months later. Also some people have office jobs, some do 18,000 steps each day… And don’t get me started on mental health.
Diagnosing medical conditions is hard for AI. We got some news on that a few days ago. It’s good at exam questions. But doesn’t perform in reality. So I wouldn’t call it health agent considering those kinds of questions. More a shaman. Or alternative practitioner / healer. (Or it’d need to stick to specific things. Or we need a few more years of progress in AI.)
I mean, I think the available tools aren’t even half bad? There’s smart watches with all kinds of features, apps, dashboards… Training modes and advise. They can help you define goals, track your period if you have that… Water intake, activity levels. It’s not AI, but there will be summaries, achievements, reminders…
Just the privacy part is a bit tricky, as most of these ecosystems come as cloud services.
