AI Chatbot Application with Google OAuth

This is a Flask-based AI chatbot application that integrates with OpenAI's GPT-3.5 API. It includes Google OAuth for user authentication and is designed to be deployed on Heroku. The chatbot can handle user inputs and generate responses using the GPT-3.5 model.

Features

• AI Chatbot: Leverages OpenAI's GPT-3.5 API for generating responses to user queries.
• Google OAuth: Secure login using Google OAuth 2.0.
• Asynchronous Requests: Non-blocking API requests for faster responses.
• Heroku Deployment: Ready to be deployed on Heroku with minimal setup.
• Environment-based Configuration: All sensitive information is stored in environment variables using a .env file.

Prerequisites

• Python 3.7+
• Heroku CLI (for deployment)
• OpenAI API Key
• Google OAuth Client ID & Secret

Getting Started

Follow these steps to get the project up and running locally or on Heroku.

1. Clone the repository

git clone https://github.com//EfremMic/ai-chatbot-app.git
cd ai-chatbot-app

2. Set up a virtual environment

It's recommended to use a virtual environment to manage your dependencies.

python3 -m venv venv
source venv/bin/activate  # On Windows, use: venv\Scripts\activate

3. Install dependencies

pip install -r requirements.txt

4. Generate a SECRET_KEY

Run the provided script to generate a SECRET_KEY for your Flask application:

python generate_secret_key.py

This will append a SECRET_KEY to your .env file. The .env file stores sensitive information and should never be pushed to version control.

5. Set up environment variables

Create a .env file in the project root with the following content:

# .env
SECRET_KEY=your_generated_secret_key
OPENAI_API_KEY=your_openai_api_key
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret

6. Run the application locally

flask run

You can now access the application at http://127.0.0.1:5000/.

7. Deploy to Heroku

If you want to deploy the app to Heroku, follow these steps:

7.1. Create a Heroku app

heroku create your-app-name

7.2. Set environment variables on Heroku

Set your environment variables on Heroku:

heroku config:set SECRET_KEY=your_secret_key
heroku config:set OPENAI_API_KEY=your_openai_api_key
heroku config:set GOOGLE_CLIENT_ID=your_google_client_id
heroku config:set GOOGLE_CLIENT_SECRET=your_google_client_secret

7.3. Push the code to Heroku

git add .
git commit -m "Initial commit"
git push heroku master

7.4. Open the app

heroku open

Your application should now be live on Heroku!

Troubleshooting

If you run into issues, here are a few steps you can take:

• Make sure your .env file contains the correct keys.
• Check that you have set up Google OAuth correctly by creating OAuth credentials in your Google Cloud Console.
• For deployment issues, ensure that you have the correct environment variables set up on Heroku using the heroku config command.
