Actually Timeline was a semantic store from what I understand-- it didn't store screenshots of what you were doing, instead apps that used the Microsoft Graph API could contribute information about what you were doing to be included in the Timeline. As far as I know, nothing used it except for MS' own apps. This new solution bypasses that problem by having no requirement for apps to use the Graph API-- it will just use an AI to deduce what the tasks were, and provide a search-like conversational experience on top of the collected images.
