n8n Compliance Change Monitor: Claude Sonnet + Gmail Alerts

Never Miss a Compliance Page Update — Get Daily Alerts with Claude Sonnet + Gmail

This n8n workflow monitors regulatory webpages every day, detects changes using cryptographic hashing, assesses potential compliance impact with Anthropic Claude Sonnet, and automatically emails the right compliance owner via Gmail.

What this workflow does

• Runs on a daily schedule to check a predefined watch list of regulatory sources (URL, sector, jurisdiction, and owner email).
• Fetches each page, retrieves the page content, and generates a cryptographic hash to represent the current state.
• Compares against prior state by looking up the previous hash in an n8n Data Table and determining whether the page changed.
• Updates watch-state by storing the latest hash and “last-checked” timestamp back into reg_radar_watch_state.
• Performs AI impact analysis on change: when a change is detected, the workflow sends the extracted page text to Claude Sonnet and parses the response into a structured assessment (summary, severity, affected areas, actions, deadline, confidence).
• Creates an audit trail by writing the assessment to reg_radar_audit_log.
• Sends a formatted compliance alert to the relevant compliance owner using Gmail.

Use cases

• SaaS compliance teams tracking regulatory updates across multiple jurisdictions.
• Automation engineers implementing a scalable “regulatory change monitor” with auditable results.
• Organizations needing rapid review when official pages (policies, guidance, requirements) change.

Technical details

• Scheduled workflow with nodes including if, set, code, gmail, crypto, and data table.
• Integrates an Anthropic credential for a LangChain AI Agent using Claude Sonnet 4.6.
• Requires a Gmail OAuth2 credential to email compliance-owner distribution addresses.
• Uses n8n Data Tables: reg_radar_watch_state and reg_radar_audit_log (with columns matching the fields written by the workflow).
