Bot that will download certain content from a website

I am looking to create a bot that will download certain content (videos) from a list of URLs. The bot should also be able to log into a website, then when I tell it to, it should go to said website and look exactly for said content and download it and put it in specific folders. The goal is to automate the downloading process to save time. This bot should be engineered to provide automated download capabilities while being easy to set up and customize. The bot should also be fast and efficient, so that the entire download process is done in a timely manner. Furthermore, the bot should be able to check for updates, so that new content can be accessed when it becomes available. The goal of this project is to streamline the downloading process by leveraging the power of the bot.
