The biohacker

Max Kline

AI Biohacker

The AI biohacker coach who designs trials before drawing conclusions.

Max Kline is the AI biohacker in Wellness Project. He coaches HRV interpretation, daily recovery readiness, structured self-experiments, and the quantified-self toolkit across CGM, sleep, and wearable data, and the app is free during early access on iPhone, Android, and web. Max won’t let you draw conclusions from one HRV reading: he helps you set a clean baseline, design a 2-week trial, and tells you whether something actually worked on you specifically, staying honest about noise.

What Max actually does

Specialist depth, not chatbot generic.

HRV interpretation in context

Max reads HRV against your baseline, training load, alcohol, sleep, and stress in one pass. Not "is 47 good?" but "is 47 normal for you given last night?"

Daily recovery readiness

Composite score from HRV deviation, RHR deviation, sleep, and prior-day load. Drives the day’s training-load suggestion.

Trial design

New compound? New protocol? Max designs a 2-week structured trial: what to measure, what your control week looks like, when to stop.

Cross-correlation reads

"Sleep score down 12% in the 2 weeks since you added evening HIIT." Specific, falsifiable, useful.

Honest about noise

Max won’t over-interpret a single bad night. He needs 7-14 days minimum before drawing a conclusion. He’ll tell you when something’s "noise, not signal."

Quantified-self toolkit

CGM, sleep tracking, HRV-guided training, breathwork experiments, fasting, cold exposure. Max coaches the experimentation framework.

Sample replies

How Max actually talks

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

My sleep score has been dropping all week
Your 7-day average is 74, down from 86 last week. You added evening HIIT Mon/Wed. High-intensity within 4 hours of sleep elevates core temp and cortisol. Try mornings. RHR confirms: 63 bpm vs 58 baseline.
Should I add ashwagandha?
Could help, but let's prove it on you specifically. 14-day trial: log your daily HRV, sleep score, and stress rating now (control week), then start ashwagandha next Monday. We'll compare week-2 to week-1. If HRV doesn't shift more than 4ms above your week-1 average, it's noise. Want me to set that up?
Is my CGM data actually useful?
Yes, but use it for patterns, not single spikes. What I look at: average glucose, time-in-range, glucose variability (CV%), and post-meal AUC. Single 'spike to 165' on a high-carb meal isn't pathological. A weekly average creeping above 100 mg/dL with widening variability is the signal.

Max reads HRV and RHR like a stock chart.

FAQ

FAQ

Is Max ok with skepticism?+
Yes. Max is the most skeptical coach in the lineup. He’d rather you test something on yourself with a clean protocol than read claims from a podcast.
What wearables does Max read?+
Oura and Fitbit integrate directly. Apple Watch, and any other wearable that writes to Apple Health on iOS or Google Health Connect on Android (Samsung Health, Garmin and others), come through those platforms, read-only. If your device pushes data into Apple Health or Health Connect, Max can read it.
Will Max recommend supplements?+
Cautiously, and always as a structured trial, not as a default. He’ll suggest evidence-tier (well-evidenced like creatine, omega-3, vitamin D) before fringe compounds.
Does Max do genetic interpretation?+
No. Wellness Project does not currently ingest 23andMe or Ancestry raw data. If you bring up well-validated variants in conversation, Max can discuss the literature, but he won’t pretend to do clinical genetic interpretation, and he’ll route anything actionable to a clinician or genetic counselor.
