We Offline is a free Chrome add-on developed by Jack. It falls under the category of Browsers, specifically Add-ons & Tools. This program allows users to backup their tweets for offline access.

Once installed, We Offline adds a browser action icon next to the address bar. Clicking on this icon while on a Weibo page will display the backup interface. Clicking the icon on any other page, or using the "Open UI" option from the Weibo page, will show the previously backed up content.

The add-on's panel page features four buttons. The "Refresh" button updates the status without any side effects. The "Save" button saves the tweets from the current page. The "Open UI" button opens the user interface, and the "Backup" button starts backing up tweets from the current page onwards. If the backup process is interrupted for any reason, refreshing the page will resume it. To ensure the add-on is working properly, users can check if the address bar changes, if the page is scrolling, or if the number of data entries increases after refreshing the UI page.
