Abstract: An electronic device with one or more processors and memory receives a user input corresponding to a request to monitor a webpage. The electronic device obtains, in accordance with a predetermined monitoring frequency, current summary information corresponding to the webpage. The electronic device determines whether the webpage includes updated content based on the summary information corresponding to the webpage. In accordance with a determination that the webpage includes updated content, the electronic device presents an indication of the updated content.
