Vitality AI Health
The car dashboard for your body
Vitality AI Health unifies your wearables, blood work, DNA, nutrition, and Epic medical records into one AI longevity dashboard. Track healthspan trends, recovery, and metabolic health. Get personalized insights and predictions, HIPAA-compliant.
There are two ways to build a consumer health AI. The fast way and the responsible way. I want to walk through what the responsible way actually requires.
I'm Duddu Venkata Ramana, Co-Founder and Head of AI & Data Science at Vitality AI Health. Kevin covered the why. Here is the how.
What it is: A production health AI platform with a continuously evaluated safety and quality layer running on top of every response Vaya gives a user.
What makes it different: Most consumer health AI claims safety but cannot prove it. We built the proof.
Across 120+ iterations on Replit, Vaya was graded continuously against four independent evaluation systems totaling 380+ automated checks: a 149-question functional-medicine question bank across 29 categories, an 80-question Dr.-Hyman-caliber clinical bank scored by 6 distinct judge personas (medical professional, health coach, compliance officer, data analyst, patient, investor) against 15 weighted clinical safety rules, a 20-scenario red team adversarial suite, and 164 system-health and data-integrity checks. We did not stop iterating until the 32-question core gate hit 32/32 passing and the red team suite hit 20/20 defended.
Then we layered Arize AX on top, with 5 evaluators and 9 production monitors at 100% sampling, so every live response is scored in real time, not just at test time. The Arize layer covers hallucination, clinical safety, RAG retrieval health, refusal appropriateness, and routing mix drift.
On May 15, we ran the same 32-question stress test against live production Vaya. The result was 0 hallucinations across all 32 questions, 10 appropriate clinical safety redirects on the questions that warranted them, and 16 successful cross-source RAG retrievals. The full audit is available on request.
The stack: Next.js 16 web app, React Native iOS and Android, Supabase backend across all three. Vaya Chat AI runs on Google Gemini with smart routing, around 85% of queries go to gemini-2.5-flash-lite for fast responses and the rest to gemini-3-flash-preview for complex cross-source reasoning. Epic FHIR integration pulls structured medical records directly from your provider, no manual PDF uploads. Wearables come in through the Terra API (60+ wearable brands) plus direct Garmin and Whoop integrations. HIPAA-compliant from day one, designed by Denis Galkin, a virtual CISO with 20+ years of experience supporting organizations in regulated environments and HIPAA Security Rule risk assessments.
Key features under the hood: Real-time clinical safety evaluator with five redlines, including a fifth redline for acute lab and vital interpretation Hallucination zero tolerance monitor on a 15-minute rolling window Refusal appropriateness evaluator so the model is helpful, not just cautious RAG retrieval health scoring on every response Routing mix drift monitor that alerts if model selection patterns shift Daily token cost cap with automated alerting Source attribution on every response, so users see exactly which data table backed each claim Audit logging on every data access and granular per-query consent controls
Benefits: Clinical-grade safety baseline that most consumer health AI products do not have Continuous quality measurement, not a one-shot demo Transparency on every Vaya response, including which data sources it pulled from
Who it's for: Anyone who would not let a consumer chatbot near their actual labs and medical records without proof that the safety layer is real. We built this for that user first.
If you have technical questions about the architecture, the data pipeline, the safety layer, or how we handle Epic FHIR, drop them below. I will answer every one.

Who hunted Vitality AI Health ?
Vitality AI Health was hunted by Rohan Chaubey. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
