Dramatron

Dramatron is an interactive co-writing tool developed by Google DeepMind that leverages large language models to help authors create screenplays and theatre scripts. It uses a hierarchical story generation approach to maintain coherence and structure across multiple levels of a narrative, from a single logline to detailed character descriptions, locations, plot points, and dialogue. Dramatron operates as a creative assistant rather than a fully autonomous system, offering human writers material to edit, adapt, and reinterpret. It was evaluated through user studies with professional playwrights and screenwriters, who found it particularly valuable for world-building, idea generation, and exploring alternative plotlines. The system can be run locally or in Google Colab, where users can integrate their own large language models by implementing sampling functions.
