Food Recognition Chatbot

SnapSnack is a food recognition chatbot that uses Twilio to receive image messages and OpenAI to recognize the food item. The chatbot then retrieves the nutritional information for the food item using the USDA API and responds with a summary of the information.

Prerequisites

To run this project, you will need the following:

• Twilio Account and Phone Number
• OpenAI Account
• USDA API Key
• Google Cloud Account

Installation

Clone the repository

To get started, clone the repository to your local machine:

git clone https://github.com/your-username/food-recognition-chatbot.git
cd food-recognition-chatbot

Set up environment variables

Create a .env file in the project directory and add your Twilio and OpenAI credentials and your USDA API key as environment variables. For example:

python -m venv venv
source venv/bin/activate  # for Mac/Linux
.\venv\Scripts\activate  # for Windows

Download the Google Cloud Vision API JSON file

Download the Google Cloud Vision API JSON file as cloud.json and place it in the project directory.

Create a virtual environment

Create a virtual environment for the project and activate it:

Copy code
python -m venv venv
source venv/bin/activate  # for Mac/Linux
.\venv\Scripts\activate  # for Windows

Install dependencies

Install the required Python packages using pip:

pip install -r requirements.txt

Run the app

Run the app with the following command:

python app.py

This will start a local server on localhost with debug mode enabled and listening on port 8080. You should see output in the terminal indicating that the server is running.

Set up ngrok

In another terminal window, run the following command to set up ngrok:

ngrok http 8080

This command will create a public URL that tunnels to your locally running app on port 8080.

Set up Twilio webhook

In the Twilio console, add the forwarding URL generated by ngrok as a webhook when "A Message Comes In". Remember to add /detect_food to the back of the webhook link.

Start using the chatbot

Send a picture of a food item to the Twilio number and the chatbot will respond with the nutritional information for the food item.

Usage

To use the chatbot, send an image message of a food item to your Twilio number. The chatbot will respond with a summary of the nutritional information for the food item, including the calories, fat content, protein content, and carbohydrate content.
