Project Overview

Automated Dietary Guide

Many individuals struggle to make confident food choices due to complex ingredient labels, unclear menus, and diverse dietary needs or goals. This often leads to stress, uncertainty, and potential health risks.

PlateMate is an AI-powered companion that provides personalized, real-time dietary guidance. Users can scan foods, log meals, and track health trends, while receiving tailored insights that adapt to their unique needs.

Problem Statement

Identifying Main Challenges

Apps Aren’t Truly Personalized

Most nutrition apps focus on basic calorie tracking and don’t adapt to allergies, health conditions, or real-time changes.

Food Choices Are Uncertain

People with dietary needs often feel confused and stressed when reading labels or menus, making it hard to know what’s safe to eat.

Lack of Guidance Leads to Risk

Without clear direction, users may accidentally follow unsafe diets or consume ingredients that harm their health and dietary goals.

Design System

This project strengthened my understanding of how thoughtful UX design can simplify complex tasks like nutrition management and support healthier daily habits. I gained practical experience in applying human-centered design principles to real user needs, especially for individuals with dietary restrictions or health conditions. Designing features such as AI-guided onboarding, smart scanning, and voice-based interactions taught me the importance of reducing cognitive load and creating intuitive, anxiety-free experiences. Using branch mark analysis and personas, helped ensure the solution reflected users’ behaviors, motivations, and challenges. This process reinforced the value of clarity, accessibility, and personalized support when designing for health-related contexts.

A key takeaway was the impact of continuous iteration and user feedback. If I were to expand this project further, I would conduct more extensive usability testing across a wider demographic to better understand unique dietary needs and cultural food patterns. Longer testing cycles would also offer deeper insights into user behavior over time, such as how consistently they log meals or engage with AI-generated suggestions. Overall, this experience strengthened my perspective as a designer who prioritizes empathy, simplicity, and adaptability—not only to improve usability, but to promote sustainable long-term habits. It also reinforced how AI-driven features, when designed responsibly, can enhance user confidence and make everyday decisions feel more supportive and approachable.
