Meet Your Coach

The Coach is an AI that already knows your health data — so you spend less time explaining and more time improving.

The problem with generic AI

You can ask any chatbot about nutrition. It will give you a reasonable answer based on general knowledge. Then you ask again tomorrow, and it has forgotten everything — your allergies, your calorie target, your sleep patterns, the protocol you committed to last week. Every conversation starts from zero. You spend more time re-explaining your situation than getting useful advice.

This is the fundamental limitation of general-purpose AI tools for health. They know a lot about nutrition in the abstract. They know nothing about you.

What makes the Coach different

Rubric’s Coach is not a general-purpose chatbot with a health theme. It is an AI that has access to your actual data — not because you told it, but because Rubric already tracks it.

Before the Coach responds to a question, it can pull:

Your nutrition logs from the past week
Sleep and activity data synced from Apple Health
Your active protocols and current adherence
Workout history
Summaries of your past Coach conversations
Your full profile — goals, dietary preferences, allergies, and medical conditions

Your safety information — allergies, medical conditions, and dietary restrictions — is always present in every interaction. The Coach does not need to look these up. They are part of its baseline context, every time, without exception.

And the Coach remembers. If you discussed a strategy for managing weekend eating last Tuesday, that context carries forward into this week’s conversations.

What you can do with the Coach

Ask about your data. “How did I do this week?” “What does my sleep look like over the past month?” “Which meals tend to put me over my calorie target?”

Get help with decisions. Paste a restaurant menu link and the Coach recommends specific dishes that fit your targets and avoid your allergens. Share a recipe and get an estimated nutrition breakdown.

Build protocols. “I want to commit to running three times a week.” The Coach helps you define the rules and set a realistic timeline.

Find patterns. “I keep exceeding my calorie target on weekends — what should I change?” The Coach pulls your recent data and identifies what is actually happening, not what you think is happening.

Get strategy, not platitudes. “I have a work dinner tonight and I’ve already eaten 1,400 calories. How should I approach it?” The Coach gives you specific, data-informed options.

What the Coach does not do

Modify your data. The Coach is strictly advisory. It can propose a protocol, suggest a meal strategy, or analyze a trend — but it never writes to your nutrition logs, health records, or protocol status. You always decide what gets recorded.

Provide medical advice. The Coach will redirect medical questions to a healthcare professional. It is not a doctor, dietitian, or therapist.

Access other users’ data. Your conversations are private and not shared with anyone.

Access your photos. Photo-based food logging is processed separately. The Coach does not see your images.

Where to find it

The Coach lives in the AI Coach tab — the third tab in the app’s navigation bar. When you open it, you will see a text input field, your recent conversations (if any), and a set of suggested conversation starters under “Looking for ideas?” to help you get started.

Type a question, and the Coach goes to work.
