LangChain: The Trendiest Web Framework of 2023, Thanks to AI

I agree with the article, LangChain is both fun and good technology (I am biased, my latest book is on LangChain - you can read it free at https://leanpub.com/langchain using the Free to Read Online link).

LlamaIndex is another library that facilitates building applications using OpenAI and Hugging Face APIs (and running local models). LlamaIndex and LangChain are useful together.

It is one thing to play with the ChatGPT web app (or mobile apps), but I think it is a better thing to write your own code to use your own text documents (and Google Docs, etc.).
