What is ChangeNotifier?
ChangeNotifier is a web monitoring tool that watches any web page for changes and sends alerts when something important updates. It supports three monitoring modes: visual monitoring using screenshot comparisons, text monitoring with word-level diffs, and element monitoring to track a specific part of a page such as a price, status badge, or paragraph. To reduce unnecessary notifications, it includes AI-powered filtering to ignore common noise like timestamps and cosmetic tweaks, plus keyword/number/regex rules and custom AI conditions. Alerts can be delivered through email, Slack, Discord, webhooks, Zapier, n8n, or RSS, and include summaries and before/after comparisons with optional screenshot attachments. Setup can be done quickly using a Chrome extension, a visual element picker, or recorded browser actions for JavaScript-heavy sites and multi-step flows.
