## Overview

Let Me Know When is a monitoring service built around one simple question: has anything changed on the pages you care about? You point it at a URL — a product page, a competitor's pricing sheet, a job board, a news source — and it checks that page on a schedule, then alerts you when the content shifts. Setup is web-based and takes only a few minutes, with no code required.

What separates it from basic page-watchers is an AI layer. The assistant interprets what changed rather than just flagging raw HTML diffs, so you can ask it for analysis of a competitor's design update or a summary of new content. Results can be delivered by email on the entry plans and by email plus Slack on higher tiers, and templates are provided for common monitoring scenarios.

Pricing is tiered by the number of sites and check frequency. At the time of writing the published plans are approximately $3.99/month for up to 10 websites and 600 checks, $9.99/month for up to 20 websites and 2,400 checks with one AI workflow and Slack notifications, and $19.99/month for up to 30 websites and 5,400 checks with five AI workflows. Annual billing is advertised as cheaper. There is a free trial on the entry plan.

- **Email and Slack alerts:** Notifications are delivered by email on all paid tiers, with Slack integration available from the Starter plan upward.

- **Market and news alerts (Trader or analyst):** Keep an eye on crypto, stock values, search trends and news sources without manually refreshing pages.
