Without KnowledgeSync you can access the same contexts and saved resources across devices, but your tabs will be different within each browser or device you use. Therefore every time you open a Context or look through your recently open windows, you will not be able to continue working where you left off.
Using KnowledgeSync - you can easily update your working tabs across browsers, profiles, and devices as shown in the video below. If you have the same Context open in two different browsers, you will see a pop-up asking whether which version of the tabs you would like to use: (A) keep whichever tabs you currently have open in your current browser, or (b) update to the most recent state of tabs synced to the cloud.
Soon, KnowledgeSync will let you sync more than your tabs across browsers and devices, such as all of your indexed files, messages, and more.
