Systems, methods, and computer-readable storage media for importing a new content item, such as a photo, document, video, email, or application, into a content item repository. A content item repository can contain a set of existing content item groups, and each content item group can include at least one content item. The system can calculate a profile for a new content item to be imported. Upon determining, based on the calculated profile, that the new content item exceeds a similarity threshold for an existing content item group, the system can insert the new content item into the content item group. Upon determining, based on the calculated profile, that the new content item does not exceed the similarity threshold for any existing content item group, the system can create a new content item group and insert the new content item therein.
