Abstract: Content-aware device selection is performed for modifying content elements in digital collaboration spaces. A content element, such as a text box or drawing space, is detected within a digital collaboration space based on input received from a first device of a first device type. A second device type to use to modify the content element is determined based on a content type of the content element. One or more devices of that second device type which are authenticated to access the digital collaboration space are identified. At least one of those authenticated devices are then prompted for input to use to modify the content element. The content element is then modified within the digital collaboration space based on the input received from at least one of those prompted devices.
