Freshify

Every year, households around the world waste over 630 million tonnes of food, costing approximately $1 trillion and contributing 8-10% of global greenhouse gas emissions. This isn't just an environmental crisis, it's hitting families financially as well. A typical American family could save around $1,600 annually by eliminating food waste. The problem exists across cultures and continents, with per capita food waste ranging from 100kg/year in North America to 5kg/year in Sub-Saharan Africa.

Freshify is a mobile app that uses push notifications to remind you when your groceries are about to expire.

Every time you come back from the grocery store, simply snap a photo of your receipt and take a photo of the items, and Freshify will (using GPT-4o's image recognition) automatically detect the items' expiration date and notify you when they're about to expire.

Freshify also comes with a recipe generator, prioritizing ingredients that are about to expire.

Here's a demo video!

I implemented the AI backend, the scanning functionalities, including the recipe scanning and image recognition. It was my first time using the OpenAI API, and I was amazed at how well it was able to recognize the items in the image.
