Let Me Know When

Let Me Know When watches web pages for you. It is a website monitoring tool that tracks changes on the sites you pick and sends an alert when something moves.

The free plan covers up to 10 websites with 600 checks a month and two checks per website per day, with email notifications only.

That is enough for casual use, though it includes no AI workflows.

Paid plans start at $9.99 a month for 20 websites, one AI workflow and Slack alerts.

Advanced costs $19.99 and gives 30 websites and five AI workflows.

Premium costs $89.99 a month, covers 50 websites and ten AI workflows, checks every hour and adds premium support.

Check frequency is the main thing you pay for as you move up.
