PageDiff

Website change monitoring in plain English, with AI alerts.

PageDiff is an AI-powered website-change monitor for teams tracking competitor and pricing pages, terms and policies, docs, announcements, job listings, and compliance pages. Instead of brittle CSS selectors or XPath, you describe what counts as a change in plain English — "tell me when the pricing changes, but ignore the cookie banner." On your schedule (as often as every five minutes), PageDiff catches the change, writes a plain-language summary, and scores how significant it is, so a reworded footer never pings you. Compare text, visual, and HTML diffs side by side. Alerts arrive by email, Slack, Discord, or a signed webhook. PageDiff is EU-hosted and GDPR-compliant, every plan is fully featured (you choose only scale), and you can preview any page free with no account. Note: PageDiff runs in the cloud, so it monitors publicly reachable pages — not pages behind a login or on an internal network.

Multi-channel alerts

Get notified by email, Slack, Discord, or a signed webhook, with CC recipients and a per-monitor significance threshold.
