FAQ

What does this website change checker do?

It runs one live AI preview on a public page, shows the detected signal, and lets you carry that setup into a saved WebMonitor monitor.

Why are price and restock tools now on this page?

They use the same underlying workflow: a URL plus a plain-English condition. The presets keep the entry point specific without splitting the same tool into several thin pages.

Do I need CSS selectors or XPath?

No. The point of this workflow is to start from intent, not selectors. You describe the outcome you want and WebMonitor handles the setup inside the product.

What happens after I submit the form?

First, the tool runs a real preview check and shows the result. After that, you can continue into the dashboard or signup flow with the same URL and prompt prefilled.

What is included for free?

You can run a live preview and save one public page as a 14-day daily monitor. Paid plans unlock more monitors, faster checks, private pages, and richer alerts.
