How it works

  1. Paste the product page's address below.
  2. Click the availability: Currently unavailable, Sold out, Out of stock.
  3. Choose When it says and enter In stock, or When it no longer says and enter Sold out.

Case does not matter. Zetlyn tells you once, when the text appears or goes. Every other change on the place is still kept in the watch's history.

Pages that change on their own

Some shops show a different text on every visit, an A/B test or a box that guesses where you live. Zetlyn reads a changed place a second time before it believes the change, and learns the texts a place flips between on its own, so those flips are not reported. A new text always is.

Mark a narrow place, the availability line, rather than the whole buy box. The narrower the place, the fewer surprises.

Where the message goes

Email, Telegram, Slack, Discord or a signed webhook, as you choose under Notifications.
