AI-powered agent that monitors Polish real estate developers' websites for price transparency compliance with 2025 regulations.

Automated PL Real Estate Developer Website Checker

Project Context and Purpose

Starting September 11, 2025, following new regulations effective from July 2025, real estate developers in Poland will be legally required to publicly display apartment prices on their websites. This project serves as an automated tool to monitor developers' compliance with these transparency requirements.

Core Functionality

The script automatically:

• Visits developer websites
• Analyzes content for specific apartment prices
• Distinguishes between actual prices and general price ranges
• Logs results with timestamps
• Generates clear responses: "Available apartment prices" or "No available apartment prices"

Technology Stack

The project leverages:

• LLM (Large Language Model) for intelligent content analysis
• Browser-Use for browser automation
• Python for process orchestration

Technical Setup Guide

This guide will help you set up the project using the browser-use package for web automation with Google's Gemini model.

Prerequisites

• Python 3.11 or higher
• A Google API key for Gemini model access
