Build a Complete GEN AI Diet Planner App using LangChain & Streamlit (Step-by-Step) | TAMIL

In this video, you'll learn how to build a complete AI Healthy Meal Planner App using LangChain, Streamlit, Python, and OpenRouter AI. This Gen AI application generates a personalized daily meal plan based on user inputs such as age, diabetic status, food preference (Veg/Non-Veg), and health goals. The app automatically calculates nutritional requirements including protein, fiber, vitamins, minerals, calories, carbohydrates, and healthy fats, then creates a balanced meal plan with breakfast, lunch, dinner, and snacks. Users can also download the generated meal plan as a PDF report. This project is perfect for Python developers, AI enthusiasts, students, freshers, and software engineers who want to build real-world Generative AI applications using LangChain and OpenRouter. You'll learn prompt engineering, LLM integration, Streamlit UI development, PDF generation, and practical AI app development skills that can be added to your portfolio.
