Empty Fridge

Empty Fridge is a Streamlit application powered by Google's Gemini models that looks at photos of your ingredients (no matter how scarce and messy) and hallucinates (in a good way) a legitimate recipe you can actually cook.

Features

• AI Vision Chef: Upload a photo of your messy pantry or fridge shelf. The app identifies the ingredients for you (so you don't have to type them out).

• Creative Recipe Generation: Uses the ingredients you have + your cravings (e.g., "Comfort Food", "Thai") to get a structured, easy-to-follow recipe.

• Nutritionist Mode: An AI agent analyzes the generated recipe to give you a rough health breakdown (Calories, Protein, Carbs).

• Barista: Suggests the perfect beverage pairing (alcoholic or non-alcoholic) based on the flavor profile of the dish.

• PDF Export: Generates a clean, downloadable PDF of the recipe so you can save it for later.

Tech Stack

• Python (backend)

• Streamlit (frontend)

• Google Gemini API (Specifically gemini-2.5-flash-lite for speed and vision capabilities)

• xhtml2pdf (For generating the PDF reports)

How to Run It

Option 1: Google Colab (Easy Way)

If you don't want to mess with local environments, I included a Jupyter Notebook (Empty Fridge.ipynb) that handles everything.

1. Open the notebook in Colab.

2. Add your Gemini API Key when prompted in the app sidebar.

3. The notebook uses ngrok to tunnel the Streamlit app so you can view it in your browser.

Option 2: Running Locally

1. Clone the repo.

2. Install requirements:

   pip install -q -U google-generativeai streamlit fpdf2 Pillow xhtml2pdf
   

3. Run the app:

   streamlit run app.py
