This AI Agent Plans, Researches & Writes Blogs Automatically using LangGraph | Agentic AI Project

CampusX · Beginner ·🤖 AI Agents & Automation ·3mo ago
In this video, we build a real AI agent using LangGraph, going beyond simple prompts to design a planning-based, production-style agent system that plans before execution, decides when internet research is required, breaks tasks into parallel subtasks, uses multiple worker agents, adds citations and images automatically, and generates a complete blog end-to-end; you’ll learn how modern AI agents are actually designed using the orchestrator–worker architecture, along with key concepts like router, planner, worker, and reducer nodes, research-powered agents with Tavily, image-aware content generation, and how to turn an AI agent into a real, interview-ready project using LangGraph, LangChain, OpenAI, Gemini, Python, and Streamlit.
