Learn LangChain.js

Put yourself on the bleeding edge of AI by harnessing the power of LangChain Expression Language to build a chatbot that has deep knowledge of a provided document. In this course, you'll use LangChain.js to build a chatbot that can answer questions on specific text - one of the holy grails of AI. First, learn about using LangChain to split text into chunks, convert chunks to vectors using OpenAI embeddings, and store them in a Supabase vector store. Next, study chains using LangChain Expression Language. Finally, tackle retrieval using vector matching to select relevant text chunks from your vector store. This enables the chatbot to answer questions specific to your data - a critical skill for real-world AI applications.
