Building a Text-to-SQL Chatbot

The text discusses the use of AI tools like Hex, LangChain, and OpenAI to create a natural language processing (NLP) chatbot that can query databases. The author initially built a simple bot using ChatGPT but faced limitations due to its knowledge cutoff. Upon discovering LangChain, they were able to improve the chatbot's efficiency with just 20 lines of code. They then used Hex to build the front end of the app, allowing users to interact directly with the data and inform their questions. The author has since enhanced the bot's accuracy by providing more context and user selections. Looking forward, they plan to incorporate memory and chat-like features while addressing rate limit issues related to OpenAI tokens.
