Notify Me When a Website Changes
Paste the URL you keep refreshing. Get a ping when the page actually updates.

Notify me when a website changes is the whole job: paste a URL, get a ping, skip the refresh loop. People type that sentence into Google because they are tired of opening the same tab on the train.
The tools they find often ask for a screenshot region or a CSS selector. That is a different product. You wanted a colleague who watches the page and texts you when the substance moves.
What the ping should say
A useful notification names the change. "The starter plan went from $29 to $39." "A Staff Engineer role appeared on the jobs index." A red overlay of a moving hero image is a screenshot, not an answer.
AyeWatch writes that summary. Page change alerts is the longer explainer. Visualping still wins if you need a pixel audit for a legal exhibit. For day-to-day watching, the summary is the product.
Push, email, or Slack
Free Preview is push and in-app, six lifetime runs, three topics, Daily or slower. No card. That is enough to prove the URL you already babysit. Pro is $9 a month. Paid plans add email, Slack, Discord, and webhooks. Pick push when minutes matter. Pick Slack when the watch is a team job.
Checks are not instant on Free Preview. If you need ASAP, that is a higher plan. Be honest with yourself about the page. A concert presale needs speed. A quarterly TOS rewrite does not.
Start a monitor in under a minute
Free Preview is six lifetime runs across three topics. No card.
Try AyeWatch freeOne URL, then the rest
Start with the page you refresh the most. Write the rule in the words you would use in Slack. Ignore layout. Ignore the cookie banner. If the first ping is useful, add the next page. If it is noise, the rule is too loose, not the idea.
This is not a Chrome extension that dies when you close the laptop. The check runs in the cloud. That is the difference between "notify me" as a wish and "notify me" as a system. If the page only exists after a login, a cloud watch of public HTML will miss it. Keep an extension for those few URLs. Use AyeWatch on the public ones you already refresh on the train.
