雷星星小助手 is a Chrome add-on that serves as a helpful assistant for automatically retrieving video addresses. This add-on is particularly useful for automatically fetching videos from platforms like WeChat public accounts, especially those in MP4 format. However, it is important to note that it cannot fetch videos from platforms like Bilibili or YouTube, as they use the Blob format.

Whether you need to download videos for offline viewing or share them with others, this add-on simplifies the process by automatically fetching the video addresses for you.

Please note that 雷星星小助手 is a free add-on available on the Chrome platform. It falls under the category of Browsers and is specifically listed under the Add-ons & Tools subcategory. It is developed by Haixiang Yan.
