Create your own ChatGPT text summarisation app using Streamlit and Langchain

Here I will explain a step by step guide for creating your own apps using ChatGPT from OpenAI using Streamlit as the app host and Langchain as the back end to interface with the model

First step is to access the OPENAI API by going here and setting up an API Key. It does mean signing up with your card payment details, so ensure you set a reasonable price cap, and try to use GPT3.5 turbo instead of GPT-4. Keep your API key somewhere secure. You will also need it later to interact with the app.
