CoWriter: Guiding Methodological and Synergetic Human-LLM Co-Authoring

CoWriter is a proactive agentic system that adapts expert human co‑authoring methodologies from cognitive science to guide the entire writing workflow and actively encourage user engagement. In an exploratory user study, authors using CoWriter expressed their perspectives more clearly, felt greater ownership of the document, and engaged with the agent 2.2× more often than a standard LLM baseline. External reader judges also rated CoWriter‑generated texts higher in human‑touch qualities such as storytelling and personal experience integration.
