Disclosed herein are methods and systems for comparing two slide decks using a compare service. The compare service generates a comparison analysis for the two slide decks based on a comparison theme selected by the user. The result of the analysis is displayed in a comparison display that includes a slide selector section, a slide pair viewer section, and a navigable change summary section. In one embodiment, the compare service allows the user to select preferred slides from the two slide decks displayed in the comparison display, and subsequently generates a new slide deck that contains only the preferred slides selected by the user.
