Site Spy

Website change monitoring, powered by AI·sitespy.app

Site Spy is a website monitoring platform that tracks any webpage for changes and notifies users when something meaningful happens. It uses AI-powered smart filters so users can describe what they care about in plain English (e.g. price drops, new listings, stock changes) and have noise like timestamps, cookie banners, and ads automatically filtered out. The product includes a web dashboard, browser extensions for Chrome and Firefox, visual diff views, a snapshot timeline, and an MCP server that lets AI agents like Claude and Cursor monitor sites directly.
