An extension to search for text at a certain interval and a notification when found?

Question

Google Chrome

Is there such an extension that searches for text on a page at a certain interval, refreshing the page and if the text is found, there will be a sound notification?

Answer 1

Try Distill Web Monitor for just such cases.
You can select the part of the page and the frequency of tracking changes, as well as a sound notification (although there are only three sounds to choose from) - in the settings "Play audio clip (for local monitor)"
