The mood at German train stations is complicated. Delays cause frustration and boredom. The challenge: to transform this rather negative aspect of travel into a positive brand experience. The idea: Turn waiting time into reading time. The OOH campaign 'Read until the train arrives' turned stations into pop-up libraries. The simple mechanics: People waiting can dive into 5-, 10-, 20-, or 30-minute versions of major literary works. Perfectly matched to the remaining waiting time. The technological centerpiece: an AI agent that decodes the tonality and writing style of the authors, while analyzing the semantic structures and narrative density of the masterpieces. This ensures that the spirit and atmosphere of the originals remain intact in all short versions. This goes far beyond simple algorithmic shortening.
