In a groundbreaking twist of entrepreneurship, 18-year-old Zach Yadegari from Long Island has leveraged AI to create Cal AI, an innovative app that analyzes food photos to provide calorie counts and nutritional breakdowns without writing original code. Projected to generate $30 million annually, Cal AI capitalizes on the power of optimized prompts using ChatGPT, rather than building complex models. The app, launched in May 2024, has already amassed 8.3 million downloads and boasts a 4.8-star rating from over 80,000 reviews, bringing in $1.4 million monthly.
Yadegari’s journey began with personal frustrations over manual calorie tracking and has evolved into a thriving startup with a diverse team. His story highlights that aspiring entrepreneurs can harness existing technology and creativity—no extensive coding or huge budgets needed—to solve real-world problems. As Cal AI aims to dethrone competitors like MyFitnessPal, it emphasizes the importance of prompt engineering in the AI-driven landscape of 2025.
