Web Research Agent

An AI-powered research agent that searches the web, analyzes multiple sources, and generates structured research reports using LangGraph.

Enter a research topic and let the agent search the web with Tavily, synthesize the results with GPT-4o-mini, and return a clear report with summaries, key findings, and sources.

---

✨ Overview

The Web Research Agent automates the research process by combining web search with AI-powered synthesis.

Instead of manually searching multiple websites and organizing information, simply provide a research query and let the agent gather and summarize relevant information.

Research Query → Web Search → Source Collection → AI Synthesis → Research Report

---

🚀 Key Features

• 🔍 Web Search Search the web for relevant information using Tavily.

• 🧠 AI-Powered Research Use GPT-4o-mini to analyze and synthesize search results.

• 🔗 LangGraph Workflow Organize the research process using a structured agent workflow.

• 📄 Structured Reports Generate reports with:

  • Summary
  • Key Findings
  • Sources

• 🎯 Custom Research Queries Research any topic directly from the command line.

• ⚡ Simple CLI Interface Start researching with a single command.

Workflow

1. The user provides a research query.
2. The Search Node sends the query to Tavily.
3. Tavily retrieves relevant web results.
4. The Synthesize Node processes the search results.
5. GPT-4o-mini analyzes the information.
6. The agent generates a structured research report.
