Synthri turns your bloodwork into a personalized wellness map. Most lab reports look like spreadsheets. Synthri turns yours into something you can actually understand — biomarker by biomarker, in plain English. HOW IT WORKS Snap a photo of your lab report (CBC, CMP, lipid panel, A1c, and more), and Synthri's AI extracts every biomarker automatically. Each value gets a clear status — Low, Optimal, Borderline, High — based on your lab's own reference ranges. Tap any biomarker for an educational explanation of what it measures, what your value suggests in context, and what lifestyle factors are commonly associated with it. ASK SYNTHRI'S ASSISTANT Chat with Synthri's AI assistant about your results. Ask what a marker means, how your biological age estimate is calculated, or what's worth raising with your doctor — and get answers in plain language, grounded in your own uploaded labs. It's built for education and wellness, never diagnosis, and always points you back to your healthcare provider for medical questions. BIOLOGICAL AGE ESTIMATES When your labs include the right markers, Synthri estimates your Phenotypic Age using a published research methodology (Levine et al., 2018), alongside a Metabolic Age wellness estimate. Each estimate is shown with its confidence level and a reminder to discuss your results with your healthcare provider. These are educational wellness estimates based on research methodology — not medical diagnoses. EXPLORE "WHAT-IF" SCENARIOS See how changes might shift your estimated age. Adjust lab values or lifestyle factors — sleep, movement, hydration, added sugar, and more — and watch your Metabolic Age estimate update in real time. These are illustrative projections to help you think about your wellness, not predictions or medical guidance. WHAT'S INCLUDED Photo-based lab upload — works with reports from Quest, Labcorp, hospital portals, and more Multi-page reports — add every page of a report so all your results are analyzed together Automatic extraction of biomarkers, values, units, and reference ranges Plain-English educational summaries for every marker Status badges so you can see at a glance which values fall outside reference ranges AI assistant that answers questions grounded in your own labs Biological age estimates (Phenotypic Age + Metabolic Age) when supported by your markers "What-if" scenario modeling for lab values and lifestyle factors Lab history and biomarker trends — upload future panels to see how your results shift over time Full account control — delete your data anytime PRIVACY FIRST Synthri only sees the labs you choose to upload. We never connect to your doctor, your hospital, or your insurance company. We don't sell your data, share it with advertisers, or use it for anything other than providing this service to you. WELLNESS, NOT MEDICAL ADVICE Synthri is a wellness and education tool. It does not provide medical diagnosis, treatment, or prescriptive advice. The insights — including biological age estimates and AI assistant responses — are for educational purposes only. Always discuss your lab results with your healthcare provider before making any health decisions. WHAT'S COMING We're continuing to build. On the roadmap: deeper trend analytics, lab-test integrations, and richer personalized insights. Built by independent developers. Designed for people who want to understand their bodies.
