A complete technical breakdown of the cognitive metrics, algorithms, and data systems that power your daily score.
Your brain is your primary performance asset, yet until now, it's been the one system you aren't measuring. Fitness trackers count steps. Sleep apps log hours. But neither tells you how well your brain is actually performing.
Until now, cognitive optimization has been guesswork. You take supplements hoping they work. You sleep and assume you recovered. But you never actually know.
Steps and heart rate don’t measure cognitive function
Taking nootropics blind with no way to measure effects
No way to know if "I feel off today" is real — or just perception
A real-time, objective metric (0-100) quantifying your cognitive readiness state. Calculated from three weighted inputs and updated daily as your data streams in.
Capacity × Recovery = Performance
If you trained hard yesterday, your cognitive capacity today may be temporarily reduced. This modifier adjusts your score based on recent physical stress from wearable training data.
Why we ask how you slept: Research shows subjective sleep quality predicts next-day performance better than wearable data alone. We combine both for accuracy.
A few minutes each day for objective cognitive data. No surveys. No subjective guessing. Real performance metrics.
A calibrated typing protocol that measures real-time cognitive throughput under varying load conditions. Type words across four phases — Calibration, Adaptive, Complex, and Winddown — to reveal how your brain handles increasing cognitive load and recovers from it.
Your cognitive baseline test — a monthly assessment establishing your maximum processing capacity under controlled conditions. 12 minutes of sustained focus that pushes your cognitive limits to find your true ceiling.
One-time API connection. We pull your HRV, sleep architecture, and recovery metrics automatically each morning — eliminating manual tracking.
Heart rate variability from overnight readings
Deep, REM, and light sleep duration
Baseline heart rate for recovery signal
Physical stress from recent workouts
Kai analyzes longitudinal data patterns to deliver specific, actionable performance insights. Not generic wellness tips — analysis tailored to YOUR cognitive performance.
Everything you need to track, optimize, and improve your cognitive performance — all in one place.
Your daily Primacy Score combines cognitive tests, wearable data, and subjective inputs into a single actionable number. Track trends over time and see what drives your performance.
Kai analyzes your patterns and delivers personalized insights. Morning and evening modes, voice check-ins, and actionable recommendations based on YOUR data.
Track supplements and lifestyle factors. The AI correlates alcohol, late meals, travel, and more with your cognitive scores to identify what impacts YOUR performance.
The free diagnostic identifies your specific constraint:
Strong baseline capacity with inconsistent daily access patterns. Characterized by energy crashes, focus issues, stress reactivity.
Cognitive ceiling has declined. Characterized by poor sleep quality, slow recovery, depleted capacity that needs rebuilding.
Three paths — choose the one that matches where you are.
Map your cognitive baseline, establish your Primacy Score, and unlock the full performance tracking platform.
Answer five sets of questions to confirm whether APEX or RESET is right for you, then get notified when pre-orders open.
