As answered by people managing SiteSpy.app and Codegres.org.
SiteSpy.app's answer
Element-level tracking lets you click on any part of a webpage to monitor just that section instead of the whole page. It also includes an MCP server so AI assistants like Claude can create watches and summarize changes directly.
SiteSpy.app's answer
Most website monitors only track full pages. Site Spy lets you pin a specific element — a price, headline, or stock status — so you get notified about the exact change you care about, not every minor page update.
SiteSpy.app's answer
