PageWatch: Website Change Monitor with AI Diffs

PageWatch: Website Change Monitor with AI Diffs ships as a ready-to-import n8n automation package: load the bundled workflow JSON, connect the credentials listed on this page, and activate it on self-hosted n8n or n8n Cloud.

Catch competitor and client page changes the moment they happen — hourly content hashing plus an AI summary of exactly what changed, alerted to Slack and email.

Watch unlimited pages from one Google Sheet — add a URL row and it's covered on the next hourly check
Strip scripts, styles, comments, and markup before hashing so ad rotation and visitor counters never trigger a false alert
AI writes a plain-English summary of exactly what changed on the page, not just that something changed
Filter out cosmetic noise with a configurable minimum change threshold
Alert both Slack and email the moment a real change is detected
Track every check in the sheet with the latest snapshot, hash, and status for a clean audit trail
No scraping SaaS subscription required — runs on plain HTTP requests you already have access to

FAQ

About this template

How long does it take to set up PageWatch: Website Change Monitor with AI Diffs?

Most people finish in minutes following the guide. If you’ve never used n8n before, budget an hour — the first workflow is always the slowest.

What if I get stuck?

Email support@n8ntemplatestore.com. Free basic support is included with every purchase, and you’ll get a reply from our team within 24 hours. If setup needs more than email, we can schedule a call.

Do I need to pay for Google Sheets?

API costs are separate and go directly to the provider — typically a few dollars a month at most for a solo business. Full breakdown is in the setup guide.

Can I customize the workflow?

Yes, completely. You own the .json — edit nodes, swap in your own prompts, re-wire the logic. Our support team can help you plan customizations over email.

What if it doesn’t work for me?

Refunds are issued only as described in our Refund Policy (https://n8ntemplatestore.com/refund-policy). Or add Setup Service at checkout for a live install and test session — pick any tier you prefer.
