A sophisticated AI-powered research automation system that performs comprehensive company research, generates structured reports, and delivers polished PDF documents with minimal human input.

## Overview

This project leverages Large Language Models and specialized AI agents to automate the process of gathering, analyzing, and synthesizing business intelligence. The system follows a structured workflow to transform a simple company name and keywords into a comprehensive, professionally formatted research report.

## Key Features

-   **Automated Research Gathering**: Conducts parallel web searches across multiple queries to gather comprehensive company information
-   **Intelligent Document Curation**: Filters and prioritizes the most relevant documents for report generation
-   **Structured Report Generation**: Creates well-organized reports with standardized sections
-   **Citation Management**: Automatically includes citations with quoted text and source URLs
-   **PDF Export**: Converts markdown reports to properly formatted PDF documents
-   **Rate Limiting**: Implements token bucket algorithm to manage API usage efficiently
## Architecture

The system is built using a modular architecture based on LangGraph's StateGraph framework:

```
### Core Components

1.  **Research Node**: Coordinates the research process using the Google Generative AI (Gemini)
2.  **Tools Node**: Executes web searches using the Tavily API
3.  **Curate Node**: Filters and processes coll
