P.S. Currently I am having some issues deploying the app . If you want to try it out you can:
1.Clone the repo in your local machine
2.Get your OpenAI API key here - https://beta.openai.com/account/api-keys
3.Create a dotenv file similar to dotenv_sample
4.Paste your OPENAI API key in the file
5.Install all the required dependencies using npm install
