Biometric AI · Powered by Claude

You track your sleep, HRV, and glucose. PseuChef is what you finally DO with that data.

Every night, PseuChef reads your Oura, Apple Health, or Dexcom — then wakes up with a meal plan tuned to today's you, not yesterday's average. Breakfast, lunch, dinner, snacks. Ready before you are.

How it works

Three steps. Zero calorie counting.

Connect a wearable. Let PseuChef analyze you overnight. Wake up with a meal plan tuned to what your body actually needs today.

01 · Connect

Link your body

Connect Oura, Apple Health, or Dexcom in 30 seconds. Your data stays encrypted and never trains a model. Don't have a wearable? Plus tier works without one.

02 · Analyze

AI reads you overnight

At 4:30 AM, two AI brains go to work. A nutritionist translates last night's recovery into today's targets. A chef turns those targets into meals that actually taste like food.

03 · Wake up fed

Meals ready before you

Breakfast, lunch, dinner, and snacks waiting on the BioSync dashboard. Tap any meal to shop the ingredients on Instacart in one move. No planning. No guesswork.

Dual-intelligence architecture

Two brains. One kitchen.

Nutrition science and culinary creativity each get their own AI, so neither compromises the other.

Nutritionist Brain

Reads your biology

Ingests last night's HRV, sleep stages, glucose curves, and recovery score. Translates raw data into precise macro targets and micronutrient priorities for today — not for an average person.

  • Grounded in peer-reviewed nutrition science (IOM, ACSM, ISSN)
  • Re-runs every 72 hours or when biometrics shift materially
  • Evidence-backed targets — no crash deficits or fad extremes
Chef Brain

Creates your meals

Takes the nutritionist's targets and crafts meals people actually want to eat. Rotates cuisines, respects your pantry, avoids yesterday's dishes, and writes recipes you can cook in the time you actually have.

  • Anti-repetition memory — you won't eat the same thing twice this week
  • Respects allergies, preferences, and what's already in your pantry
  • One-tap grocery list + Instacart handoff for the ingredients you need
BioSync · Pro

Meals that change when you do — automatically, overnight.

Stressful day. HRV dips. Sleep gets short. Glucose wakes up elevated. With BioSync, tomorrow's meals already know. You don't have to update anything, log anything, or think about it.

Built for your actual kitchen

More than a meal plan.

Tools for the gap between "here's what to eat" and "dinner is on the table."

Voice cooking mode

Hands covered in chicken marinade? Say "next step" and PseuChef reads the recipe out loud. Built-in timers. Voice-activated substitutions when you realize you're out of paprika.

Smart pantry

Snap a photo of your fridge. PseuChef remembers what you have and plans around it. No more wilted spinach in the crisper.

Chef chat

"Can I swap salmon for cod?" "Make this dairy-free." Ask the chef brain anything — it knows your plan and adjusts on the fly.

Instacart handoff

Today's meals → tonight's groceries in one tap. Attribution-ready deep link; cart populated with just the ingredients you don't already have.

Weekly planner

Dinner parties on Friday. Meal prep Sunday. Long run Wednesday. PseuChef plans around your actual calendar, not a theoretical week.

Grounded in peer review

Science that shows its work.

PseuChef's targets draw from the same peer-reviewed sources your doctor reads. Every recommendation has a citation you can click.

Honest answers

Frequently asked questions

What's the difference between Plus and Pro?
Plus gives you unlimited AI meals, voice cooking, and the smart pantry — no wearable required. It's the right call if you don't own an Oura, Apple Watch, Dexcom, or Withings. Pro (BioSync) is everything Plus has, plus overnight biometric analysis: your meals change when your sleep, HRV, or glucose changes. If you already wear a tracker, Pro is what the app was built for.
Do I need a wearable?
Nope. Plus tier works without one. PseuChef still generates AI-personalized meals based on your goals, preferences, and pantry — it just doesn't adapt overnight from biometrics.
Is this medical advice?
No. PseuChef is a general wellness app. It does not diagnose, treat, cure, or prevent any disease. See the full disclaimer below. If you have a medical condition, are pregnant, or manage a condition with a CGM, consult your clinician before making changes.
What data do you collect? Where does it go?
We collect what's needed to generate your plan — biometrics (if you connect a wearable), preferences, pantry, meal history. Your data is encrypted in transit and at rest, never sold, and never trains a model. Full details in our privacy policy.
Can I cancel anytime?
Yes. Subscriptions are billed through your Apple ID and can be canceled anytime from Settings → your Apple ID → Subscriptions on iPhone. No phone calls, no retention emails, no dark patterns.
Why is it called PseuChef?
"Pseu" = pseudo — an AI playing chef so you don't have to.
Not a medical device. PseuChef is a general wellness app. It does not diagnose, treat, cure, or prevent any disease. Information shown is for educational and general-wellness purposes only and is not a substitute for professional medical, nutritional, or dietary advice. If you have a medical condition, are pregnant, or manage a condition with a CGM, consult your clinician before making changes.
