Precision biomarker analysis · Clinically-grounded methodology

Your biological age,
precisely measured.

LongevAI applies validated biomarker methodology — facial phenotyping, lifestyle data, and clinical risk factors — to quantify your biological age with the precision of a longevity clinic. Inspired by the Horvath epigenetic clock and Levine phenotypic age. Accessible at $9.

Why biological age

Your birthday is just a number.
Your biology tells a different story.

🔬

3× more predictive

Biological age predicts health outcomes 3× better than chronological age.

Levine et al., 2018
🧬

10+ years reversible

Epigenetic research shows your lifestyle can accelerate — or reverse — aging by 10+ years.

Horvath et al., 2013
📊

Targeted intervention

Early detection of accelerated aging enables targeted, evidence-based intervention before symptoms appear.

How it works

Three steps to your
biological age report

1

Upload your photo

Our AI analyzes 47 facial biomarkers linked to cardiovascular and metabolic aging — skin texture, vascular patterns, and micro-expressions associated with biological age.

2

Complete the clinical assessment

12 evidence-based questions covering sleep quality, inflammation markers, lifestyle risk factors, and family health history — calibrated against longitudinal aging studies.

3

Get your Biological Age Score

A composite score with personalized, RCT-backed recommendations. Understand exactly how your body compares to your calendar age — and what you can do about it.

The science

Built on decades of
peer-reviewed epigenetic research

Methodology

Our model is inspired by the phenotypic age methodology of Levine et al. (2018, Clinical Chemistry), and draws from the Horvath epigenetic clock, GrimAge, and DunedinPACE — the gold standards of biological age research.

FAQ

Common questions

Is this medically validated?+
LongevAI is not a medical device and does not provide medical diagnoses. Our assessment is an estimation tool inspired by peer-reviewed phenotypic age methodology (Levine et al., 2018). It is designed for informational and wellness purposes — not to replace clinical testing or medical advice. Think of it as a highly informed screening tool that surfaces what to discuss with your doctor.
How is biological age different from my real age?+
Chronological age is simply how many years you've been alive. Biological age reflects the functional state of your cells, tissues, and organ systems — shaped by genetics, lifestyle, stress, sleep, and diet. Someone who is 45 chronologically might have a biological age of 38 (younger) or 53 (older), depending on how they've lived. Biological age is what actually predicts health outcomes.
What do you do with my photo?+
Your photo is processed by our AI model to extract 47 facial biomarkers linked to aging. It is never shared with third parties, never used for advertising, and never stored beyond what's needed to generate your report. We are committed to HIPAA-conscious data handling practices.
How accurate is the AI?+
Our facial biomarker model achieves strong correlation with lab-based biological age assessments across validation datasets. Results should be interpreted as estimates within a ±3–5 year range, not precise clinical measurements. We are continuously improving our model with new research.
Is $9 really all it costs?+
Yes — $9, one time. No subscription, no upsell, no hidden fees. You get the full Biological Age Score, facial biomarker analysis, clinical risk profile, personalized longevity recommendations, and a downloadable PDF report. That's it.
The question you can't un-ask

What if your body is older
than you think it is?

Most people don't find out until it's too late. For $9, get clarity now — and a science-backed plan to change the trajectory.
