Description
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
Setup
- Create a Google Sheet with two tabs: Pages (columns:
url,page_name,last_content,last_checked) and Change Log (columns:date,page_name,url,summary) - Add the URLs you want to monitor in the Pages tab — leave
last_contentandlast_checkedempty - Connect your Google Sheets OAuth2, Gmail OAuth2, and OpenAI API credentials
- Update the Google Sheet document in all four Google Sheets nodes
- Set your email address in the Send Change Alert node
- Run once to save baselines, then activate the workflow
