Yadegari and his friends were brainstorming use cases for OpenAI’s Images API, which enables developers to create apps that utilize OpenAI models that can understand and generate visual data. “I had struggled with calorie tracking in my past,” he says.


“I wanted to build a better calorie tracking app, something that’s at least better for my life.” For Yadegari, this meant a faster solution that would not require manual data entry.


His idea was an app that can track calories just by processing photos of the food you eat. He and his co-founder built the app whenever they could, even during their high school classes.


Once Yadegari got Cal AI “to a point where it was accurate enough that it was effective,” he began sharing and promoting it.
