The longevity advisor

Evelyn Cross

AI longevity advisor

Your AI longevity coach for healthspan, biomarkers, and the long game.

Evelyn Cross is the AI longevity advisor in Wellness Project. She coaches healthspan, biomarker and lab-trajectory analysis, risk-stratification framing, and the sleep-first leverage hierarchy, and the app is free during early access on iPhone, Android, and web. Evelyn reads biomarker trajectories like a financial analyst reads earnings: comfortable saying “we don’t have strong evidence for that yet” and equally comfortable saying “your sleep is more predictive than your supplement stack will ever be.”

What Evelyn actually does

Specialist depth, not chatbot generic.

Lab trajectory analysis

Every biomarker plotted longitudinally. Evelyn reads the trend, not the single panel, which is how clinicians who do this well actually think.

Risk-stratification framing

ApoB, hsCRP, fasting insulin, HbA1c: the markers that move long-term outcomes. Evelyn frames in terms of risk distributions, not pass/fail.

Sleep as the master lever

Evelyn treats sleep architecture and HRV as the two most important non-genetic levers. Most "longevity protocols" should start there before adding compounds.

Always defers to clinicians

For anything out-of-range or clinically concerning, Evelyn explicitly recommends working with a longevity-aware physician. She’s educational; she doesn’t prescribe.

Honest about evidence

Senolytics, rapamycin, epigenetic reprogramming: Evelyn tracks the literature and reports honestly: "promising preclinical, no human RCTs yet, here’s what we’d watch for."

Cross-domain pattern reads

HRV down + sleep short + RHR up = the early signal of chronic load. Evelyn watches this composite, not any single number in isolation.

How Evelyn actually talks

Real exchange shape from the ai longevity advisor. Tone is consistent — direct, specific, grounded in your data.

Am I sleeping enough?

On nights you sleep under 7 hours, your RHR runs 2 bpm higher the next morning and HRV drops 4 ms vs baseline. You've logged 11 of those in the last 30 days. For longevity, the goal is fewer of them. Both numbers rebound when sleep does.

Should I take rapamycin?

That's a doctor conversation, not an app conversation. The animal evidence is strong; the human evidence is small and ongoing. Anything off-label belongs with a longevity-aware physician, not me. What I will say: before that question is even worth asking, sleep, ApoB, and hsCRP move more outcome than any compound you could add. Get those into target range first.

My ApoB came back at 95.

95 sits in the standard 'normal' range but above what most longevity-aware lipidologists target (commonly under 80, with tighter goals for higher-risk profiles). Trajectory matters more than any single reading, so what was it last year? If it's stable, dietary patterns lower in saturated fat and higher in soluble fiber are the canonical first lever; published trials suggest meaningful single-digit-to-low-double-digit percent reductions in 8-12 weeks, with individual response varying. If it's rising, that's a doctor conversation about your full lipid picture, not an app one.

FAQ

Is Evelyn a doctor?

No. Evelyn is an AI longevity advisor, informational, not medical. She’ll explicitly route you to a clinician for anything that requires a prescription, a test, or a diagnosis.

Does she know about Bryan Johnson, Peter Attia, Rhonda Patrick?

Yes, she’s read their protocols and the underlying literature. She doesn’t evangelize any of them; she’ll discuss the evidence and your data in context.

How current is Evelyn’s knowledge?

She’s tuned on current longevity literature with regular updates. For anything she’s uncertain about, she’ll say "I’d want to verify the latest" rather than guess.

Can Evelyn help me build a longevity protocol?

Yes. She’ll walk you through the leverage hierarchy (sleep → exercise → metabolic markers → targeted compounds), help you pick measurements, and check in across months as data comes back.
