AI Chat

What is AI Chat?

Nutrivine's AI Chat is your personal nutrition assistant built right into the app. Ask questions about your diet, snap a photo of your meal for instant analysis, explore your nutrition history with data-driven insights, and get actionable recommendations — all in a natural conversation.

Key Features

Personalized Nutrition Advice

The AI knows your goals, your dietary preferences, and what you've eaten today. Ask anything from "How much protein have I had today?" to "What should I eat for dinner to hit my macro targets?" and get answers grounded in your actual data — not generic advice.

Food Photo Analysis

Take a photo of your meal or pick one from your gallery, and the AI will identify each food item, estimate portion sizes, and show you the calorie and macro breakdown. You can then add recognized foods directly to your diary with a single tap.

Data Queries & Insights

Ask questions about your nutrition history and the AI will analyze your tracking data to uncover patterns. Responses can include inline charts and data tables to help you visualize trends like weekly protein intake, calorie patterns, or micronutrient gaps over time.

In-App Navigation

Ask the AI how to do something in the app and it will guide you there directly. Say "how do I adjust my calorie goal?" or "set up my meal reminders" and a tap-to-navigate button appears in the response, taking you straight to the right settings screen without hunting through menus.

Smart Suggestions

Not sure what to ask? The chat offers context-aware suggestion chips based on the time of day — breakfast ideas in the morning, dinner suggestions in the evening, and daily insight prompts in between. Tap any suggestion to start a conversation, or shuffle for more ideas.

Health & Wearable Integration

If you've connected a health service like Apple Health, Health Connect, Garmin, or Strava, the AI also factors in your activity data - steps, active calories, sleep quality, heart rate, HRV, and recovery score - to give you a fuller picture of your overall wellness. This includes smart calorie adjustment (your calorie goal adapts based on actual activity) and sleep-aware meal timing suggestions.

How It Works

When you send a message, the AI analyzes your question alongside your local nutrition data to give you personalized, context-aware responses:

1. Your question is sent to our AI processing service
2. Relevant context from your local data (today's meals, nutrition goals, health metrics, profile) is included to personalize the response
3. The AI generates a response tailored to your specific situation
4. The response streams back to you in real time

For data queries, there is an additional step: the AI generates a query that runs locally on your device, then interprets the results and presents them with charts or tables when relevant.

What Data Does It Use?

The AI chat uses data stored locally on your device to provide personalized answers:

• Today's food log: what you've eaten, calories, and macros
• Your nutrition goals: calorie target, macro splits, micronutrient goals
• Your profile: age, sex, activity level, and biometrics
• Recent trends: weekly averages and patterns in your diet
• Wellness preferences: dietary goals, allergies, health conditions, and foods to avoid
• Health metrics: steps, active calories, sleep, heart rate, HRV, and recovery score (if a health service is connected)
• Active calorie adjustment: if enabled, your calorie goal is adjusted based on actual activity vs estimated baseline
• Your history: logging streak, frequently logged foods, and weight trend

Managing Conversations

Your conversations are saved so you can revisit them anytime. From the chat screen you can:

• Search past conversations by title or content
• Pin important conversations so they always appear at the top
• Share a conversation via a web link (you can revoke access at any time)
• Delete any conversation you no longer need

You can also provide feedback on any AI response with thumbs up or thumbs down, or copy a response to your clipboard.

Free & Premium

Free users have a daily limit on messages, food photo analyses, and data queries. These limits reset every day. Premium users enjoy unlimited access to all AI chat features.

Privacy & Data Protection

Your privacy is our top priority:

• No personal information is shared: your name, email, and location are never sent to AI providers
• Nutrition data is anonymized: only the nutritional context needed for your question is included, with no identifying details
• Conversations are stored locally: your chat history lives on your device
• No training on your data: your conversations are not used to train AI models
• You control your data: delete any conversation at any time

Tips for Best Results

• Be specific: instead of "What should I eat?", try "What's a high-protein dinner under 500 calories?"
• Ask about your data: "How are my iron levels this week?" or "Am I getting enough fiber?"
• Send a photo: snap your meal and ask "What's in this?" for instant food identification
• Explore your history: "Show me my calorie trend over the past two weeks" or "Which days did I hit my protein goal?"
• Request meal plans: "Plan my meals for tomorrow to hit my macro goals"
• Get alternatives: "What can I eat instead of rice for fewer carbs?"
• Review your day: "Rate my meals today" or "What nutrients am I missing?"
• Navigate the app: "How do I change my protein goal?", "Take me to meal reminders", or "Where do I log my weight?" — the AI will open the right screen for you

Important Notes

AI responses are informational and educational. They are based on general nutrition science and your personal tracking data. Always consult a healthcare professional for medical decisions, dietary restrictions related to health conditions, or if you have concerns about your nutritional status.
