What is SmartEat AI?

SmartEat AI is an innovative platform that combines artificial intelligence and nutritional management to deliver personalized meal planning experiences. The system analyzes dietary preferences, restrictions, and nutritional goals to generate customized recommendations tailored to each user’s profile.
SmartEat AI was developed as a Master’s Thesis Project (TFM) for the Specialization Course in Artificial Intelligence and Big Data.

​
The Problem We Solve

Planning a balanced diet represents a significant challenge for many people due to:
  • Lack of nutritional knowledge - Understanding macronutrients and proper portion sizes
  • Limited time - Meal planning takes significant effort and research
  • Difficulty maintaining consistency - Keeping track of dietary habits over time
  • Rigid solutions - Most apps offer calorie tracking without intelligent adaptation
While calorie tracking applications exist, few combine intelligent analysis, automatic meal plan generation, and conversational capabilities to dynamically adapt to the user’s diet.
