Have a bot watch any web page and ping you when it changes

Instead of refreshing a page, tell a bot what matters on it. It checks on a schedule and pings you only when that changes.

What the bot does

  1. Takes a link and what you care about, like a restock, a new listing or an appointment slot opening.
  2. Saves how the page looks now.
  3. Checks again on a schedule.
  4. Messages you only when that thing changes.

What you end up with

One ping when it matters, and no more refreshing.

Copy-paste prompt

Fill in the [brackets]. Then paste it into any tool below.

Copy this prompt
Watch this page: [link]. What matters: [back in stock / new listing / appointment slot opens / status or policy change]. Check it [every morning]. Message me only when that changes, with the old and new value and the link. Don't buy, book or sign up for anything.
