Start a workflow from the change
Open Workflows, click New workflow and set Runs to When a watched web page changes. Pick the tile, and if you like, type words into Only when a changed line contains. Every step after that can read the change: {{change.text}} is the AI sentence or the changed lines, {{change.addedText}} and {{change.removedText}} are the lines themselves, {{change.host}} and {{change.widget}} say where it came from.
