Overview
About DiffHook
DiffHook is a real-time web-change monitoring service that watches pages, prices, policies, APIs, RSS/JSON feeds and specific page elements and instantly delivers structured alerts to Slack, email, webhooks and other tools; it uses AI-powered change detection (Cloudflare AI) to filter out cosmetic noise, surface only meaningful or semantic changes, summarize what changed, and help teams act faster on competitor price moves, compliance updates, vendor outages or brand issues.
