Web watch card
A web watch card checks a page on a schedule and notices when it changes — a changelog, a price, a status page, a competitor’s pricing.
Paste the address and choose how often to check.
The Whole page, only the part Between two phrases (e.g. between “Latest release” and “Older releases”), or matches of a pattern.
The first check is the starting point. After that, every change is recorded with what was added and removed.
With Tell connected agents when it changes on, every agent connected by an arrow gets a message about the change — so an agent can react on its own: update the docs for a new library version, say, or write you a summary.
Check now, Pause and Resume are always at hand. The card reads the page as it’s served, so text drawn later by scripts on the page isn’t seen.
