I Built an AI-Powered Website Monitor — Here's How It Works

Hey folks! 👋 I've been working on PulseWatch — an AI-powered website monitoring tool that tracks changes on any webpage and sends instant notifications. I wanted to share how I built it and what makes it different from existing solutions. The Problem We all need to track changes on websites sometimes — price drops on Amazon, new job postings, API documentation updates, stock availability, or news articles.
