+# LangGraph Comparative Review Agent
+
+## Overview
+
+This repository contains a LangGraph agent that, given three entities, builds a comparative review table. The agent:
+
+1. Generates 3‑5 comparison criteria using an LLM.
+2. For each entity‑criterion pair performs a Tavily web search and collects a short note.
+3. Builds a Markdown table with rows = criteria, columns = entities.
+4. Produces a short verdict recommending the best entity for each use case.
+
+The agent is implemented in `src/main.py` and can be run from the command line.
+
+## Requirements
+
+```bash
+pip install -r requirements.txt
+```
+
+The following environment variables must be set:
+
+- `OPENAI_API_KEY` – key for the OpenAI model used by LangChain.
+- `TAVILY_API_KEY` – key for the Tavily API.
+
+## Usage
+
+```bash
+# Default demo – compares Chroma, FAISS, Qdrant
+python -m src.main
+
+# Custom entities
+python -m src.main "Entity1" "Entity2" "Entity3"
+```
+
+The script prints the generated criteria, the comparison table, and the verdict.
