Nutrition Memory OS
Powtain
Nutrition tracking without the tracking.
Powtain passively captures how you actually eat - meals, snacks, drinks, bites, sips, and leftovers - then turns it into accurate food vitals and personalized insights.

Eating moment captured
Meal, drink, and shared side enter the timeline.
Meal understood
Bites, sips, and portions update the nutrition memory.
Insight returned
Protein, sugar, saturated fat, and simple next steps are ready.
The input problem
Food logging breaks because real life is messy.
Most nutrition apps expect you to manually enter every meal, snack, drink, and portion. But people forget, skip small bites, miss drinks, and underestimate shared plates or unfinished meals.

usable signal
Manual logging takes too much effort
Search boxes, corrections, and generic portions add friction before you get any useful insight.
Small events change the day
Drinks, bites, snacks, refills, and sauces rarely make it into a clean calorie log.
Meals are dynamic
Shared plates, leftovers, and second servings need a timeline, not a static entry.
Bad input leads to weak insights
Better capture gives Powtain enough context to return useful, personal food vitals.

How Powtain works
Powtain captures the meal process.
Powtain helps understand how eating actually happens over time - not just what appears in one photo - then turns meals, bites, sips, leftovers, and patterns into plain-language food vitals tied to your goals.
Passive by default: spend less time logging and more time living.
More accurate than memory: designed for bites, sips, snacks, drinks, shared plates, and unfinished portions.
Personalized food vitals: protein, sugar, carbs, saturated fat, calories, and trend changes when useful.
Simple next actions: clear, personalized guidance instead of overwhelming dashboards.
A nutrition timeline: see eating patterns across meals, days, and weeks.

Is Powtain fully automatic?
Powtain is designed to reduce manual effort and improve capture. Some confirmation or correction may still be useful when the meal is ambiguous.
Is it more accurate than a single food photo?
Powtain is built around meal-process understanding, so it can account for bites, sips, drinks, shared plates, and leftovers that a single static photo can miss.
What are food vitals?
Food vitals are nutrition signals tied to your goals, such as protein, sugar, carbs, saturated fat, calories, weekly averages, and week-over-week changes.
Do I have to understand nutrition data?
No. Powtain turns your history into plain-language patterns and simple next actions instead of forcing you to decode every chart.
Is Powtain medical advice?
No. Powtain is not a doctor, dietitian, diagnosis, or treatment service. If you have a medical condition or need personalized nutrition guidance, talk to a qualified healthcare professional.
