AI Macro Tracker
Project Overview
Macro.ai is an AI-powered macro tracking web application that makes nutrition logging fast and intuitive. Built using the MERN stack, it allows users to log meals using natural language, scan barcodes for packaged foods, and get instant macro breakdowns (calories, protein, carbs, fat) through AI assistance. The app is designed to be responsive, fast, and web-based, catering to users who want a simplified nutrition tracking experience without manual data entry.
