Heres a code snippet that takes in a user input and feeds it into ChatGPT and returns the response. An OpenAI API key is required for it to work. The prompt can be amended to suit your needs/to create your own custom agents.

/*
Press `cmd+shift+enter` and enter the text you want to send to ChatGPT.
