Rejuve.AI - AI-powered decentralized longevity research platform with token rewards

What is Rejuve.AI

We've all been there. You look in the mirror, see the gray hairs appearing, feel the occasional ache in your knees after a long walk, and wonder—just how old is my body really? Your chronological age says 40, but something tells you that number doesn't tell the whole story. Maybe you've read about biohackers who seem to defy aging, or seen headlines about "biological age" tests, and you've wondered: is there a way to actually measure how fast my body is aging?

This question—simple yet profound—is what drives everything we do at Rejuve.AI.

After years of working at the intersection of artificial intelligence, blockchain, and longevity science, we realized something important: the future of health shouldn't just be for the privileged few. It should be accessible, participatory, and rewarding for everyone. That's why we built Rejuve.AI—the world's first decentralized longevity research platform that combines cutting-edge AI with blockchain technology to give you a deeper understanding of your body's true aging process.

Supported by the SingularityNET Foundation, our platform allows users to contribute their health data through our mobile app, earn RJV tokens for their contributions, and receive personalized longevity recommendations powered by advanced AI models. We're not just building another health app. We're creating a global research network where your data matters—and you're compensated for it.

Our Longevity App is already live on both iOS and Android, partnering with renowned institutions like TruDiagnostic, OpenCures, and RejuveBio to bring you scientific rigor alongside personal empowerment. We've integrated data from major public datasets like NHANES and UK Biobank, and we're building the International Longevity Research Database (IRLDB)—a decentralized repository of real-world health data that could help unlock the secrets of human aging.

When you use Rejuve.AI, you're not just tracking numbers. You're becoming part of a movement that's redefining what it means to age—and you're getting rewarded for contributing to something bigger than yourself.

Core Features of Rejuve.AI

We didn't build these features in a conference room debating what users might want. We built them because real people—biohackers, health enthusiasts, researchers—told us exactly what they needed. Here's how each feature came to be, and why it matters for you.

Biological Age Assessment started with a simple observation: everyone knows their birthday, but nobody knows their body's real age. We developed two complementary models to solve this. RejuveAge-Q is our questionnaire-based model trained on over 100 health variables from NHANES data—it gives you a solid baseline in just minutes. For users who want deeper insight, LinAge2 analyzes blood biomarkers using a model developed by Fong et al. (published in npj Aging, 2025) that actually outperforms epigenetic clocks in predicting mortality and healthspan. One of our early users, a 45-year-old marathon runner, was shocked to discover his biological age was 38—validation that his lifestyle choices were paying off. Another user found her biological age was 52, despite being 44—information that prompted her to investigate underlying health issues she'd otherwise have missed.

Wearable Device Sync emerged from our conversations with users who were already tracking their health but couldn't see the bigger picture. We integrated with FitBit, Garmin, Oura Ring, and Apple Watch so your real-time movement, sleep, and heart rate data becomes part of your longevity assessment. No manual entry. No friction. One user told us that seeing his sleep quality correlated with his RejuveAge-Q score motivated him to prioritize rest—something he'd been neglecting.

Lab Data Upload lets you import blood test results, genetic reports, and other laboratory data. This isn't just for show—adding blood biomarker data significantly improves our model's accuracy. When you upload your Quest Diagnostics results or NAD Lab panel, you're both getting a better assessment and contributing valuable data to our research database.

LongevityGPT is our AI-powered personalized health coach—the feature our users are most excited about. Rather than staring at confusing dashboards, you have a conversation. Ask questions like "What does my LinAge2 score mean?" or "Which intervention should I prioritize first?" LongevityGPT synthesizes outputs from all our models and speaks to you in plain language. We built this because a user told us, "I have all this data, but I have no idea what to do with it." Now she has a virtual health coach in her pocket.

RJV Token Rewards are where our Web3 philosophy becomes tangible. You earn RJV tokens by completing health questionnaires, syncing your wearable devices, uploading lab data, referring friends, and participating in data collection campaigns. One active user in our beta community earned enough RJV to get a 30% discount on NAD+ supplements from one of our partner brands. Your health data has value—and we believe you should be compensated for sharing it.

Decentralized N-of-1 Trials let you run your own personal experiments. Want to know if intermittent fasting actually affects your biological age? Design a trial, collect the data, and let our Bayesian optimization engine analyze the results. This feature is inspired by the biohacker community—we've talked to dozens of people who spend hundreds of dollars on supplements with no way to know if they actually work. Now they can find out.

NFT Incentives ensure you maintain ownership and control over your data. Through our NFT system, you retain sovereignty over your health information while still contributing to collective research goals.

Who Uses Rejuve.AI

We've found that our users generally fall into five groups—and you might recognize yourself in more than one.

Biohackers are perhaps our most passionate community. These are people who've already tried everything: intermittent fasting, cold exposure, supplements,，严格的睡眠 schedule. They want to quantify whether their interventions actually work. Our decentralized N-of-1 trials are designed specifically for them. One biohacker in our community ran a 90-day experiment comparing two different NAD+ precursors, using blood markers and our LinAge2 model to measure results. He now has hard data to guide his supplement stack—not just anecdotal feelings.

Health Enthusiasts are curious about their bodies but don't want to go to extremes. They want to know: am I aging faster or slower than average? What lifestyle changes would make the biggest difference? For them, RejuveAge-Q provides an accessible entry point—no blood draw required—and LongevityGPT gives personalized guidance without overwhelming them with data.

Longevity Researchers see Rejuve.AI as a way to participate in cutting-edge science. They're contributing to the International Longevity Research Database, earning RJV tokens for their contributions, and in some cases, gaining access to research findings before they're published. Several academic researchers have reached out to collaborate on studies using our anonymized, aggregated data.

People Seeking Healthy Aging may not identify as "biohackers" or "researchers"—they simply want to live longer, healthier lives. They find our AI health coach (LongevityGPT) invaluable because it takes all the complex health data and translates it into plain language. One user told us, "I finally understand what my cholesterol numbers actually mean for my future health."

Web3 Enthusiasts are drawn to our decentralized approach. They see Rejuve.AI as a real-world use case for blockchain technology—something beyond speculation and NFTs. They appreciate the transparency of our token economy and the fact that our platform actually produces valuable research while demonstrating that Web3 can do social good.

Technical Features of Rejuve.AI

We believe you deserve to understand the technology behind your health insights. Here's what makes our platform tick—and why it matters for the accuracy of what you learn about yourself.

RejuveAge-Q is our questionnaire-based biological age model. Built on data from the National Health and Nutrition Examination Survey (NHANES), it incorporates over 100 health variables—including lifestyle factors, medical history, and physiological measurements. What makes it powerful is the breadth of variables we consider. Two people with the same chronological age might have very different RejuveAge-Q scores based on their sleep patterns, stress levels, exercise habits, and more. We've validated this model against multiple datasets, and the results consistently show that RejuveAge-Q correlates strongly with actual health outcomes.

LinAge2 represents the next level of biological age assessment. Developed by Fong and colleagues and published in npj Aging in 2025, this blood-based model analyzes specific biomarkers to determine your biological age. Here's why we're excited about it: in head-to-head comparisons, LinAge2 actually outperformed traditional epigenetic clocks in predicting both mortality and healthspan. That matters because epigenetic clocks have been the gold standard—but they don't always translate to actionable health predictions. LinAge2 does. If you've ever gotten your blood panel done and wondered what all those numbers mean for your longevity, this model is for you.

Delphi is our newest model, published in Nature in 2025 by Shmatko et al. While RejuveAge-Q tells you how old you are biologically, and LinAge2 refines that with blood data, Delphi projects forward: it predicts morbidity risk and healthspan—the number of years you'll likely live in good health. This is the question everyone actually wants answered: not just "how old am I?" but "how many healthy years do I have ahead?"

LongevityGPT sits at the center of everything. It's not just a chatbot—it's our AI health coach that synthesizes outputs from RejuveAge-Q, LinAge2, and Delphi into coherent, personalized guidance. Built on top of our AI infrastructure, it can answer questions like "Should I prioritize sleep or exercise first?" or "My LinAge2 dropped 2 years after taking NMN—Is that real or coincidence?" The system uses Retrieval-Augmented Generation (RAG) to ensure responses are grounded in scientific evidence, not generic health advice.

OpenCog Hyperon AGI Engine powers our platform's advanced reasoning capabilities. Developed by SingularityNET, this is a next-generation neuro-symbolic AI framework that goes beyond pattern recognition. It can perform biological pathway reasoning—understanding how different biological systems interact and how interventions in one area might affect others. This is what separates Rejuve.AI from a simple calculator: we can actually reason about your health in context.

IRLP (International Longevity Research Database) is our decentralized data infrastructure. Unlike traditional research databases controlled by single entities, IRLDB is built on blockchain principles—transparent, immutable, and community-governed. We're collecting longitudinal data from biohackers and self-experimenters who want their real-world experiences to advance science. This isn't just big data for its own sake; it's curated, quality-assured data that could reveal insights impossible to find in controlled clinical trials.

Frequently Asked Questions

<card type="faq" title="What does "biological age" actually mean?"> Your chronological age is simply the number of years since you were born. Your biological age reflects how fast your body is actually aging at a cellular and physiological level—it can be higher or lower than your chronological age depending on genetics, lifestyle, environment, and health interventions. Biological age is calculated using markers like epigenetic modifications, blood biomarkers, lifestyle factors, and physiological measurements. It's a more meaningful indicator of your actual health status and longevity potential.
