Key AI Capabilities

​
1. Weekly Plan Generation

When you ask Smarty to generate a plan, the AI:
  1. Retrieves your profile (goals, preferences, restrictions)
  2. Calculates daily calorie and macro targets
  3. Uses machine learning to select appropriate recipes
  4. Distributes meals across 7 days and your chosen meal frequency
  5. Ensures nutritional balance and variety
  6. Saves the plan to your account
Example prompts:
  • “Create my weekly meal plan”
  • “Generate a new plan for me”
  • “I need a fresh meal plan starting Monday”

​
2. Recipe Search by Criteria

Smarty can search the recipe database using natural language criteria:Search by:
  • Ingredients (“recipes with chicken and broccoli”)
  • Calories (“low-calorie desserts under 200 calories”)
  • Macros (“high-protein, low-carb meals”)
  • Diet type (“vegan dinner ideas”)
  • Meal type (“quick breakfast recipes”)
  • Multiple criteria (“gluten-free lunch under 400 calories”)
Smarty returns a list of matching recipes with nutritional information.

​
3. Meal Modification

Don’t like a specific meal in your plan? Ask Smarty to change it:
  1. Specify which meal you want to replace (day and meal type)
  2. Optionally provide criteria for the replacement
  3. Smarty uses AI to find a suitable alternative
  4. The plan updates automatically
Example prompts:
  • “Replace Wednesday’s dinner”
  • “Change tomorrow’s breakfast to something with eggs”
  • “Swap Friday lunch for a vegan option”

​
4. Recipe Swap Suggestions

Smarty can suggest alternatives for any recipe using a KNN (K-Nearest Neighbors) machine learning model:
  1. You request a swap for a specific recipe
  2. The ML model finds nutritionally similar recipes
  3. Smarty presents alternatives matching your preferences
  4. You can accept or request another suggestion
This feature is also available directly in the My Plan interface.

​
5. Profile & Preference Updates

Update your dietary information conversationally:Examples:
  • “Add gluten allergy to my restrictions”
  • “I don’t like mushrooms anymore”
  • “Change my goal to weight maintenance”
  • “Update my diet type to pescatarian”
Smarty updates your profile and confirms the changes.

Check Your Profile: Ensure your profile is up-to-date for the most accurate recommendations.
