Let Me Know When

Let Me Know When is an AI-powered website monitoring platform that helps you track changes on virtually any webpage and get notified the moment something important happens. Instead of manually checking sites every day, you can set up monitors for specific pages and define what you care about—then receive alerts by email or Slack when changes are detected.

The service is designed for both personal and professional monitoring. Track price drops and promotions on e-commerce pages, detect when an out-of-stock item becomes available again, or watch competitors for new product launches, messaging updates, and redesigns. For marketing and SEO workflows, it can follow content edits, on-page SEO shifts, and other site updates that may affect visibility. It’s also useful for monitoring job boards, event ticket availability, customer reviews, software version pages, and general news or media sources.

Beyond simple change detection, Let Me Know When includes an AI assistant that analyzes monitored pages and surfaces actionable insights—helping you understand what changed and why it may matter. The platform supports a free plan and offers paid tiers for users who need more monitoring capacity and team-friendly integrations like Slack.

Whether you’re tracking market signals, competitive moves, or operational reliability like uptime, Let Me Know When provides a centralized way to watch the web and respond quickly when conditions change. more
