Nutri Coach AI is an innovative, AI-powered nutrition assistant that democratizes access to personalized, genetically informed health coaching. The system automates the interpretation of genetic testing reports (Nutri DNA PDFs) through a multi-stage pipeline: PDF extraction using `pdf plumber`, data cleaning & normalization, rule-based genetic interpretation via a YAML knowledge base, and integration of Large Language Models (LLM) for intelligent reasoning and contextual explanations. This hybrid approach combines the transparency of rule engines with LLMs’ nuanced capabilities, generating four personalized outputs—Nutrition Plans, Fitness Recommendations, Supplement Protocols, and Lifestyle Modification. Nutri Coach AI empowers individuals, fitness coaches, and healthcare providers to translate complex genetic insights into actionable, evidence-based nutrition and lifestyle interventions—addressing limitations of generic apps and costly traditional services. The project delivers a fully functional web application, robust API, comprehensive documentation, and validation methodologies to guarantee clinical accuracy and user trust.
