Building AI Assistants with LangChain and LangGraph: A Journey of Discovery

Developing artificial intelligence (AI) assistants that can perform complex tasks has been a long-standing challenge in the field. Recently, I embarked on a journey to build such an assistant using LangChain and LangGraph, two powerful tools for building AI agents. In this article, I’ll share my experiences and insights gained from this project, highlighting key patterns and lessons learned along the way.
