Detect Content Changes Instantly

Monitor any web page for text, visual, and structural changes. Know the moment content is added, removed, or modified.

The Problem

Web content changes constantly — articles get updated silently, policies are revised without notice, documentation shifts, and terms of service evolve. Without automated monitoring, these changes slip through undetected.

The Solution

SiteChangeTracker captures both visual screenshots and full HTML content of any page. Its diff engine highlights exactly what changed — added paragraphs, removed sections, modified text, and visual layout shifts. Review changes in a clean, readable format.

Frequently Asked Questions

What types of content changes can be detected?

SiteChangeTracker detects text changes, image changes, layout modifications, metadata updates, and structural HTML changes. Essentially, if it is visible on the page or present in the HTML, it can be detected.

Can I monitor PDF documents or files?

SiteChangeTracker monitors web pages rendered in a browser. It does not directly monitor downloadable files like PDFs, but it can monitor the page that hosts the download link.

How accurate is the change detection?

Very accurate. SiteChangeTracker uses both pixel-level screenshot comparison and character-level HTML diffing to catch even the smallest changes.
