Frequently asked questions

How does AlertChecker work?

Write a plain-English statement describing what must become true to be alerted — e.g. "This item is back in stock: example.com/product". AlertChecker's AI periodically checks the web and emails you as soon as your statement becomes true.

How specific should my alert statement be?

The more specific, the better. Rather than "PlayStation 5 in stock", try "PS5 disc edition is in stock at direct.playstation.com/en-gb/ps5". Including a URL and precise conditions reduces false positives.

Do I have to provide a URL?

Not necessarily. For specific product pages, include a URL in your statement for more precise monitoring. For general topics like "S&P 500 dropped 3% today" or "SpaceX Starship launch tomorrow", no URL is needed.

How often are alerts checked?

Checking frequency depends on overall demand and the complexity of your alert. Supporters (donors) receive higher priority and more frequent checks.

How can I stop receiving alerts?

Every alert email contains an unsubscribe link. You can also manage your alerts (including deleting or deactivating them) from the My Alerts page.

Is AlertChecker free?

Yes — but users on the free plan have lower checking priority. An optional donation will help cover running costs and moves you onto the Supporter plan, giving your alerts higher checking priority for one year.
