Monitor legal policy changes with Google Sheets, Gmail and GPT-4o

Terms of Service Change Watcher with AI Summaries Automatically monitors Terms of Service, Privacy Policy, and other legal pages for changes. When content changes are detected, GPT-4o analyzes the old vs new text and emails you a plain-English summary with an impact rating.

How it works Every day at 8 AM, the workflow reads your list of URLs from a Google Sheet Each page is fetched and stripped to plain text The text is compared against the previously stored version If a change is detected, the old and new content are sent to GPT-4o for analysis You receive an email with a summary of exactly what changed and how it impacts you All changes are logged to a Change Log sheet for a historical record
