Cortex: Your AI Longevity Strategist

An intelligence layer that turns biometrics into confident next steps.

Cortex is the intelligence layer inside Metric, built to make sense of the messy stream of sleep scores, workout files, blood pressure checks, and meal logs you create every day. Instead of memorising biomarker targets, you can ask a question in natural language and watch the app build a plan grounded in your actual physiology.

Why longevity needs an intelligence layer

Your Apple Watch, smart scale, and nutrition tracker already collect more than enough data for longevity planning. The missing piece has been synthesis. Cortex reviews fresh readings, historical context, and the goals you set during onboarding, then prioritises the decision that moves you forward today. The result is less dashboard hopping and more clarity on what to do next.

Inside the Cortex experience

Ask a simple question—How is my aging rate trending? What should I eat after tonight’s workout?—and Cortex orchestrates the right tools behind the scenes. Each response includes clear reasoning, linked visuals, and the action you can take immediately.

  • Quick Snapshot summarises the latest signals across cardio, recovery, body composition, and nutrition so every prompt starts with a calibrated baseline.
  • Concern Assessment ranks which biomarkers sit furthest from their recommended zones and explains why they matter for healthspan.
  • Visual Gauges render tap-to-expand comparisons that show whether a metric is improving, stable, or slipping in the context of your peers.
  • Trend Charts highlight 90-day trajectories for VO₂ max, resting heart rate, aging rate, and more, making progress and setbacks unmistakable.
  • Nutrition Plans translate remaining macros and saved foods into complete meal ideas that respect your preferences and schedule.
  • Sleep and training nudges surface when recovery debt piles up or cardio load climbs too quickly, so you can course-correct before burnout.

We built Cortex because longevity work should feel like a conversation with a scientist who knows your history, not like managing a spreadsheet.

Trusted by design

Every answer is anchored to data you can open, inspect, and validate. Tap a gauge to see the underlying chart, tap a recommendation to learn why it was prioritised, and explore the sources log whenever you want the raw sample. Cortex never invents a data point, which means you can depend on it for decisions that influence long-term health.

Signals reviewed per prompt 20+ biomarkers Quick Snapshot blends cardiovascular, metabolic, and recovery markers before Cortex speaks.

Prompt to try

“Cortex, has my aging rate improved since I started strength training last month? Recommend two habits to double down on this week.”

Who Cortex is for

Cortex serves anyone who wants to extend healthspan without hiring a full-time coach. Busy parents get concise guidance in between meetings. Competitive age-group athletes receive training load insights that protect their recovery. Clinicians and coaches can use Cortex as a shared source of truth when reviewing a client’s progress.

The science behind the guidance

Cortex leans on published research linking HRV, VO₂ max, strength training density, sleep regularity, and metabolic flexibility to longevity outcomes. By fusing those biomarkers with your behaviour patterns, Cortex can quantify whether interventions like zone two blocks, protein timing, or earlier bedtimes are creating the right physiological response.
