Systems, methods, devices, and computer program products are provided for providing a user with access to information stored in a datastore. A multimodal system operatively coupled to the datastore is configured to communicate with the user via a user device. The multimodal system is configured to receive a request from the user to communicate with the user through a user interface of the user device. In response to the received request, the multimodal system generates a multimodal document. The generated multimodal document includes instructions allowing for communication with the user using a plurality of different user interface modalities that may be available on a user device. The multimodal system then serves the multimodal document to the user device using a communication interface. The multimodal system is configured to only publish one multimodal document at a time for a given user session so that the user may seamlessly switch between user interface modalities that may be available on the user device or on another user device.
