The health assistant that reads all of your data, over years
Most health chats read one device, or one lab report. Vaya Chat reads your blood work, DEXA, DNA, wearable, food log, supplements and medications together, across every year you have on file, and it is held to safety rules enforced in code.
It reads everything you have, over years
Blood work, DEXA, DNA, your wearable day by day, food log, supplements and medications sit in one dated timeline that goes back years, not just your latest report.
It looks for the cause, not just the number
When a marker moves, Vaya lines it up with what changed around it and tells you which explanation the data supports, which it does not, and what test would settle it.
It tells you when it does not know
If a value was never measured, Vaya says so. It never fills a gap with an average or a guess.
Safety is enforced in code
Vaya never states a dose and never says a test “rules out” a condition. Medication and supplement questions get an interaction audit, and emergencies are routed to care. These rules run in code, after the model, so they cannot be talked out of.
Every citation is real
References come only from a verified catalogue of guidelines and studies. Fabricated citations are caught before they reach you.
Try the questions Vaya is built for: “Why did my free testosterone drop between my last two draws?”, “What did my HRV look like in the 90 days before each blood test?”, “Which of my supplements could interact with my medication?”
