JUNA AI Coach

Meet JUNA, your personal AI nutrition coach powered by Claude that learns your metabolic patterns.

JUNA is your personal AI nutrition coach -- not a generic chatbot. JUNA understands your metabolic data, dietary patterns, body composition trends, and goals, and uses that context to provide coaching that is specific to you.

What is JUNA?

JUNA is an AI coaching assistant built into NutriJourney, powered by Claude. Unlike generic AI assistants, JUNA has real-time access to your:

Food logs and nutrient intake patterns
Body composition data and weight trends
Calibrated TDEE and macro targets
Trigger correlations and metabolic patterns
Engagement history and progress milestones

This means every response JUNA gives is grounded in your actual data, not generic advice.

What JUNA Can Help With

Meal suggestions -- Based on your remaining macros, nutrient gaps, and food preferences
Nutrient gap analysis -- Identifying micronutrient deficiencies in your recent intake
Progress interpretation -- Explaining what your weight trend means in context (e.g., "your weight is up 2 lbs but your sodium was double your average yesterday -- this is water, not fat")
Recipe ideas -- Suggestions that fit your macro targets and use ingredients you have on hand
Restaurant ordering guidance -- Help choosing meals at partner restaurants that align with your goals
Workout nutrition -- Pre and post-workout meal timing and composition advice
General wellness -- Sleep, stress, recovery, and how they affect your metabolism

Quick Action Chips

Below the chat input, JUNA offers context-aware quick action chips that change based on:

Time of day -- Morning chips focus on breakfast and daily planning; evening chips focus on reflection and next-day prep
Recent activity -- If you just logged a meal, chips might suggest "Analyze this meal" or "What am I missing today?"
Your situation -- If you have not logged food yet today, a chip might prompt "Help me plan today's meals"

Tap any chip to start a focused conversation on that topic.

How JUNA Learns

JUNA does not rely on a static profile. Your coaching context is rebuilt dynamically from:

Calibrated TDEE -- Your metabolically-calibrated calorie target, not a generic formula
Body composition trends -- Recent weight direction, trust-weighted averages, and pattern changes
Food preferences -- What you actually eat, not just what you say you like
Engagement patterns -- How often you log, what features you use, where you might need encouragement
Trigger correlations -- JUNA knows that your weight spikes after high-sodium days and factors that into advice

As your data grows, JUNA's coaching becomes more precise and personalized.

The "Explain Before Showing" Protocol

JUNA follows a strict coaching philosophy: explain the reasoning before giving the recommendation. This means:

JUNA will not just say "eat 180g of protein today" -- it will explain why that target makes sense for your current lean mass, activity level, and goal
Weight trend interpretations come with the underlying data -- trigger correlations, trust scores, and context
Meal suggestions include the nutritional reasoning, not just the food

No black box. You always understand the "why" behind JUNA's coaching.
